The Running Man

Meet Eamon McCarthy, Eamon is Perrin Brewing’s residential Hoses and High Lows expert. Some say he is the first high low driver to ever pull off the no look, back up though the barrel populated cellar, and somehow not hit anything, maneuver. I have witnessed it and it is truly impressive how fast he can no look back up through the busy brewery. It is truly an impressive feat.

Eamon, whose nickname around the brewery is Eamo, came to Perrin Brewing after a three-year stretch at New Holland Brewing Company where he came to know other Perrin employees, Director of Brewing John Stewart, Logistics man Adam LeClaire, and Head Brewer Bill VanEenenaam. Eamon started out as a high low driving specialist and quickly transferred into cellar man extraordinaire. He’s been changing the cella’ game ever since. When asked about his hobbies, he replied with “My hobbies are pretty simple. I like sterile filters, dry hopping, grape fruiting beer and CIPS. I also like running and sleeping but mostly the cellar work”.

Eamon is not joking around when he says running is his hobby. Eamon adores running so much that he runs to and from work. He owns a car but prefers the old mode of transportation. His two good legs. You may be saying to yourself, ‘well running to and from work sounds good. That is very healthy. I wish I could run to work and back, but I just live too far away.’ Eamo the spawn of Hermes himself, doesn’t say that. He runs 8.3 miles to the brewery and 8.3 miles’ home from the brewery, for a grand total of just over 16.5 miles. That is more than a 25K every day. Eamon runs more than the 5/3 Riverbank run on a daily basis.

He attended Grand Valley State University’s Hospitality and Tourism Management program. Then moved south to run the city of Chicago, literally. Eamon went down to Chicago to manage and run a suite at Wrigley Field for a few years. Eamon said that if he was not in the beer business he would mostly be back in the hospitality or restaurant business. “I got into brewing because it’s a labor of love. I love beer and enjoy working to make something that I love. Not many people can say that about their profession. Not only am I able to work and create something I am passionate about, but I also get to make something that other people love to enjoy. It is truly nice”.

If you think you could keep pace with Eamon “The Running Man” McCarthy, the best way for you to find him is to lace up and start running. Or, post up at Fratellis, on the Westside. He stops in after every run for a nice slice of pizza. Wait there until you see a running man in a reflective jacket. Director of Brewing, John Stewart bought him a beautiful reflective jacket due to the fact that every brewer at Perrin has almost hit Eamon with their cars on the way to work. Eamon is single and ready to mingle, you just need to catch him first.

Here are some Eamon fast facts that will help jump start your relationship:

Favorite beer on tap: Lil’ Griz
All-time favorite Perrin beer: Roeselare
First legal beer: Guinness
Current favorite non-Perrin beer: Stone’s Xocoveza
Favorite movie: I Heart Huckabees
Favorite radio station: Selena Gomez station on Pandora
Favorite vacation destination: Toronto, Canada
Sports team: Die hard Detroit Lions fan
Favorite West Michigan place to drink: Logan’s Alley
Eamon’s favorite lunch item is the Hummus Platter, but when time does not allow him food, he likes to drink a No Problems, Perrin’s session IPA.

There you have it; you have now met Eamon “The Running Man” McCarthy. 

Festival of Barrel Aged Beer (FOBAB)

The 13th annual Festival of Barrel Aged Beer (FOBAB) falls in the same category as Mardi Gras, The Carnival of Rio de Janeiro and Up Helly Aa Fire Festival; in other words, it is a must attend in your life time experience.  FOBAB is held in Chicago once a year and boasts hundreds of barrel aged beers, along with ciders from breweries around the nation. During this two-day festival, attendees can sample beers from twelve categories such as: sours, strong ales, ciders, meads, traditional and pale beer. The festival is then wrapped up in an award ceremony for the 3rd, 2nd and 1st best beer in each category and then the Best of Show beer.

Perrin Brewing Company was nice enough to send some of our production team down to the festival this year. The night before the festival we spent the evening at the Goose Island Brewing Company’s Brewer’s Dinner. This dinner was held at their barrel storage facility which was retrofitted with dim lights, a live pianist, lite candles and boasted a 5 course meal (catered by the Publican) with multiple Goose Island beers on tap including multiple variants of their famed Bourbon County Brand Stout.                 

Outside of our festival “obligations”, the time in Chicago gave us the opportunity to check out what the Chicago beer scene had to offer.  Ten years ago Goose Island was the only brewing putting out a significant amount of beer.  Fast forward to present day.  Chicago now boasts over 30 craft breweries, with the likes of Revolution, Half Acre, and Pipeworks leading the charge.  Three days and a limited amount of time, we set out to sip on as many Chicago suds as time allowed.  During our time in the Windy City, we were fortunate enough to experience a guided tour of Goose Island’s production facility and barrel warehouse, featuring exclusive samples of some rare yet to be release beers.  Both were extremely impressive and we were able to glean a tid bit or two on how to more efficiently operate back here in Comstock Park.  Beers were sampled and darts were thrown at West Loop’s Haymarket Brewery after one of our festival sessions on Saturday afternoon.  Brunch was had at Revolution on Saturday morning.  Looking back on it, I think we did alright, and left more than impressed with the Second City’s brewing culture, and yes, we did stop at Three Floyds on the way home. 

The actual festival was held at the UIC Forum right in Downtown Chicago. There were three sessions spread over two days of barrel aged glory. As we strolled through the aisles of beers proudly displaying our Perrin attire, we were stopped for a handshake and congratulations on having “the best beer here” by a fan, referring to our No Rules Vietnamese Porter. Then moments later, another person, then another! All of this happened within just a few minutes of walking into the festival. We instantly decided to find our No Rules among the aisles, and It wasn’t hard to find. There in the already crowded festival was a quite large, line-ish looking gathering of people waiting to get their sample glasses filled by none other than No Rules. Each session of the festival, No Rules was one of the first kegs to go. That, along with the dozens of people singling us out just to tell us how awesome our beer is, gave us very high hopes for the upcoming award ceremony.

No Rules wasn’t the only beer Perrin had entered in the competition though. Roeselare was in the running, as well as Lil’ Griz. After visiting the sour beer area and hearing the amazing volunteers who pour the beer recommend everyone try Roeselare our confidence was soaring. Unfortunately, we did not come home with any hardware. We did, however, come home with a lot of great feedback, some new Perrin fans, and an experience we will never forget.   

Kettle Sour

Kettle Sour Brewing

About our Kettle Sour on Tap

Written by Brewer Bryan Bastow

Sour beers are some of the most complex, diverse, and mysterious styles in the brewing world. Making sours beers well is an art form that takes great skill, knowledge, and experience.  Producing sour beers is one of my favorite aspects of being a brewer because it’s so wildly different from making non-sour beers and requires a well developed knowledge base along with original creativity and often some improvisation. That being said I’m happy to announce the arrival of our newest sour beer creation: The “Kettle Sour”. Our kettle sour was a truly enjoyable and intriguing brew to produce, as it involves several aspects that are unique compared to our usual sour offerings.  This project is the first attempt at Perrin to make a kettle sour beer, as well as the first time using the different techniques involved with ‘hot-side’ souring. The beer is best described as an “Americanized” version of a lambic or Berliner Wiesse that is imprinted with our own unique twists. The kettle sour is a newly developed style that is gaining popularity, especially among craft brewers in the United States. Kettle sours are often presented as a cost effective way for brewers that are new to making sour beers to produce a consistently good tasting sour without the extensive procedures involved with traditional souring methods. As a beer style that is still being developed and defined, each brewery seems to have their own unique preferences and methods for producing a kettle sour. As a completely new style within the sour beer category, kettle sours are a step towards having several different classifications of sour beers rather than just a few.  Our production manager, John Stewart, is a strong advocate for producing kettle sours as well as diversifying sour styles, which he believes could reach the same vast classifications found within a huge style category such as ales. Referring to the different techniques used for souring beers John states, “It’s really using an ingredient we know and utilizing it in new ways.” He goes on “We’re using the lactobacillus bacteria in different ways and experimenting with the possibilities of how to produce sour beers. When we have brewers experimenting with new procedures it opens the doors to new souring techniques and drives the evolution of new styles.”  As more experimentation takes place within this area, the more likely it will lead to some cool new styles. The kettle sour style is very important because it represents the beginning and furthering of sour beer evolution that is currently taking place. As brewers, it is truly exciting to not only see beer style evolution happen but be a part of it and participate in developing these new possibilities from the start.

John was the mastermind behind this recipe and an effective, though lesser used sour brewing technique. Most traditional sour beer is produced though inoculation of lactic acid bacteria or wild yeast followed by aging in a barrel or other vessel ranging from 6 months to several years.  What differs in our kettle sour process was the inoculation of lactobacillus took place not in the barrel but in the brewhouse (also known as the “hot-side” of the brewing process). This technique creates several production advantages; the primary factor being aging time is reduced from upwards of a year to just a couple days. The beer was also boiled in the kettle directly following the souring process to completely kill off the lactic acid producing bacteria. The result is microbiologically stable wort free of bacteria prior to fermentation that contains the great acidity flavor that we all love. ‘Hot-side’ souring procedure avoids presenting bacteria into the cellar or tanks, and in turn virtually eliminates the risk of bacterial cross contamination of other non-sour beers. Although lactobacillus makes great sour beers it can be detrimental if it is present in any non-sour beer. Proper cellar practices and extensive micro testing in the lab are conducted to avoid and ensure all our production beers are free of such microbes.  As the lab guy responsible for testing and ensuring our brewery and all non-sour beers are free of bacteria such as lactobacillus, the kettle sour was a welcomed change in souring procedure. The process used for the Kettle Sour was able to reduce the nervous reaction I have any time a sour product enters our cellar. Quick turn times, micro stability and down right delicious acidic flavor makes this kettle souring technique stand apart from others.


The Process:

The kettle sour is a great example of simple use of ingredients paired with masterful use of technique and some new innovations to create a beer with complex flavor profile and character. The malt bill consists of just 2-row malt and malted wheat. The mash was spilt up into two parts another unique step to this brewing process. The brewing technique revolved around producing a small partial batch of highly sour wort then lowering that acidity by adding another portion of wort back to it. The process started by mashing in one third of the total grist, which is 10 barrels for our 30 barrel brewhouse. Following the mash and lauter procedures, a short 10 minute boil was conducted to kill off any microbes which would ensure the wort was free of any bacteria so the only thing that would be growing during the propagation step was the lacto we inoculated with. The wort was cooled then transferred into the mash mixer which would act as the souring vessel in this process. Once in the mash tun we had all requirements needed for lactobacillus to grow and multiply: sugars for food, nutrients, anaerobic environment, and ideal temperature.

At this point we inoculated the wort with the bacterium species Lactobacillus delbrueckii. The mixer was left on at a slow speed and CO2 was gently but continually added to the vessel. This would ensure the ideal conditions were provided for quick propagation and high production of lactic acid. The bacterium was left to do its thing and kick out the flavor over the next 48 hours. This two day period was the extent of the souring stage resulting in the sharp tart flavor we were aiming to produce. During this time and throughout the process both pH and total acidity were measured to confirm the lactobacillus was working properly and creating the acid profile we wanted to reach. Once the acidity reached a desired level and we were satisfied with the taste the newly soured wort was transferred to the kettle. Next the second part of the mash consisting of the majority of the total grist was mashed in and lautered in to the kettle. The mash temperature for this beer was very low (144oF) in order to produce highly fermentable sugars and leave the beer with little to no residual sugar. Once the full 30 bbl of wort was in the kettle it was boiled for 75 minutes. The boil process in brewing serves several purposes including isomerizing hop alpha acids, evaporating water which raises the gravity, lowers pH, caramelizes sugars, etc. The greatest importance of the boil process for this beer was the sterilization of the wort by killing off any microbes that might be in the beer, in particular the large amount of lactobacillus that had been growing and multiplying over the last two days. From this point on we had a beer that featured the sour/tart flavor and was also microbiologically stable and free of any bacteria. Once the beer was in a fermentation tank, our house yeast was used to ferment the beer as we closely monitored pH, gravity, and acidity levels though out the ‘clean’ fermentation.  From start to finish this beer only took 19 days to sour/’age’, ferment, and package. This is an incredibly short time to produce a sour beer compared to others that may take years to reach the same acid level and tart characteristics.

The Result:

As I taste the end result of this new brewing project I’m totally satisfied with this beer, a mighty fine example of what a sour beer should be, mighty fine. I think most of the brew team would agree that sour beers are some of our favorite beers to make as they always present interesting challenges for us to explore and experiment with. This kettle sour has a very light body and very low residual sugar content with an original gravity of 9.8 oPlato and a low ABV content of 3.7%. It has a light golden almost straw color with a thin brightly colored and vanishing head, along with a high clarity and brightness.  Consisting of very light malt character and very low bitterness and little to no hop flavor, the acidity is able to shine through as the focus that represents the overall taste of the beer. Our head brewer ‘Wild Bill’ VanEenenaam describes the beer as light, crisp, and refreshing, making it the perfect summer time brew. Our Kettle Sour has a flavor profile that is defined by a light body and strong acidity at the fore-front, the same as any classic traditional Berliner Wiesse. There is an up-front sharp lactic acid sourness that is the distinguishing character of the beer. The tart flavor adds depth, complexity, and interestingly presents some slightly fruity, bubblegum, grape, and tropical notes that accentuate the acidity.

Following the same serving practices as the Berliner Wiesse style, this beer will be served with an optional syrup addition when you come to get your pint in the taproom. With some help from the kitchen we’ve cooked up both raspberry syrup and the more traditional (and more difficult to find) woodruff syrup. The syrups are lightly added to this style to slightly lower or cut down the sourness which results in a balance of the beer’s acidity with some sweetness. I encourage you to try the beer in all 3 forms: straight up (like a G), with raspberry syrup (red), and finally with woodruff syrup (green).  This will give you the full spectrum of the beer and the style we wanted to produce.

 It’s always good when the brew team gets the opportunity to play around with different or new brewing techniques.  Furthermore there is still much that can be learned from making kettle sour beers. There is still a very wide range of experimentation that can take place into how sour beers can be produced and how brewers can best utilize ingredients such as lacto bacteria. In my opinion as a brewer it is not only fun and interesting, but also somewhat of a responsibility to use the modern technology, equipment, and procedures at hand in order to produce very traditional styles and the ‘old school’ flavor profiles associated with different beer styles. Although kettle sours are often objected by some who believe the new methods involved are not true to the traditional sour styles, we hope the beer we’ve made will win you over. Remember in the end we should embrace experimenting with new techniques to make sour beers, and focus on the most important factor: How does the beer taste? We hope this kettle sour will satisfy all you sour beer lovers that enjoy mouth-puckering goodness, and also remain accessible to those of you who are new to sour beer and have not yet been converted to the awesomeness that is sour beer.


Justy Bear

Meet the Team

Justin Stewart

Meet Justin Stewart, he is not to be confused with the great John Stewart or the not so great but still good Josh Stewart of the Perrin Brew team. Although they are all brothers and have many things in common, Justin is his own special person. Otherwise known as Justy Bear to all who are lucky enough to know him. He is also referred to as Perrin’s Sweetheart by our Quality Control man, Bryan “Boomer” Bastow.

Justin began working at Perrin Brewing Company in March of 2013 and previously worked at Saugatuck Brewing Company, located in, you guessed it, Saugatuck, MI. He attended Grand Rapids Community College as a science major. Justin is the Head Cellar man here at Perrin, he is in charge of all of the shiny tanks you can see through the windows. Once the beer is knocked out into the fermenters, he is now the man with the plan. Between fermentation, dry-hopping, fruit additions, CO2 levels, transfers, and filters. It is all under Justin’s domain.

 When asked about why he chose to pursue brewing as his career, he answered “Brewing has a lot going on all the time, there is constantly something new every day. It really stimulates the mind and body. You’re constantly learning something new and how to avoid problems or issues that can occur. It gives you a pretty good workout at the same time.” In confidence “Justy Bear” has been known to say that he attracts the ladies with his bulging muscles and keeps them with his overwhelming caring demeanor. His favorite movie is The Lucky One, while his favorite Pandora radio station is 90’s pop. He likes long walks but longer shuffle board tables. He is something of a shuffle puck master around the Perrin taproom and declares he is the best in the brewery, in the most humble way possible.

 “If I wasn’t working in the beer industry, I would definitely be a stay at home dad.” Stated Perrin’s Sweetheart. But for all of you who were wondering, Justin does not have any children at the moment. He is available, so come on in to the taproom and ask to meet the wonderfully enchanting Justy Bear. He may take you to his favorite vacation spot up north, or to watch his favorite sports team, the Fighting Irish. In his free time he likes to exercise (transformation Tuesdays) and game.

Alright, back to the beer part of it. These are a little fun beer facts about Justin:

First Beer- Miller High Life

Favorite Perrin Beer on tap- Bilbo’s “Bitter” Baggins

Favorite Perrin Beer of all time- No Rules

Favorite Beer Style- Sours

Favorite non-Perrin Beer- Skullspliter Orkney

Favorite Perrin Lunch Item- Revenge of the pacifist with a side of Mac n’ Cheese

Favorite West Michigan place to drink is Our Tavern because they have super long shuffleboard tables

Perrin’s Lil’Griz was named after Justin because during the month of November, no matter how hard he tried, he could not grow a beard. He simply looked like a little grizzly bear.

There you have it. You have now officially met Justin “Justy Bear” Stewart. Perrin’s Sweetheart and the namesake for Lil’s Griz. There is no way that all these words can describe what a man Justin is, and that’s why we included a picture of him on here as well.

Frankenmuth Festival-World Expo of Beer

from brewer, Connor Klopcic  

In this brewer's blog, I will be telling you about my trip to the World Expo of Beer in Frankenmuth, Michigan. 

As our head brewer began asking for volunteers to go work a beer festival in Frankenmuth I thought it would be a cool, fun, and new experience, since I am new to Perrin and have yet to go to any festivals. I really wanted to go and see what they were all about, from a brewer’s perspective (I have been to festivals before but only as a general admission participant). 

It started with me and Eamon (another Perrin production team member) packing up a couple of our four pour jockey boxes, a banner and a couple of other things we thought we would need, and began our journey to Michigan's "Little Bavaria" Frankenmuth. 

We arrived in Frankenmuth with enough time to eat lunch at Frankenmuth Brewery, and try every beer they had on tap. We were not disappointed. Their beer was solid and so was their food, a must if you are in the area. After lunch we went on to set up for the actual event. We set up our jockey boxes; hooked up the kegs and made sure our booth represented Perrin well. From there we had a brewers meeting that went over rules and where we were presented with our medals. Perrin had four beers that medaled. 

Roeselare won Gold in the sour category

Call the Banners won Gold in the Scottish category

Sweet Potato Porter won Silver in the Porter category 

Poop Your Pants Chocolate Bock won Bronze in the Bock category

We had all medaled beers with the exception of Poop Your Pants at the event. 

 Once the festival had officially started and people began to pour in, the fun really began to start. Our booth was bombarded with people wondering what beer we brought and they had many questions about both the beer and the brewery. Talking with passionate Michigan beer people was a wonderful experience. I love beer and do not get the chance to talk about it enough, which was probably my favorite thing about the festival. That and the amazing assortment of beers offered. There were about 70 different breweries attending the event and over 250 different beers. 

Periodically throughout the night, Eamon and I would go around and sample a number of different beers from many smaller breweries that we have not been given the chance to taste before. The most surprising were the breweries from Ontario, Canada. They were not surprising because they had outlandish styles or anything but they had solid styles that just tasted really good. My personal favorite Canadian beer had to be Nickel Brook Brewing Company's Bolshevik Bastard, a Russian Imperial Stout. 

The fact of the matter is that there were just so many different beers that ranged from Smirnoff's new Grapefruit to Goose Island's many variations of Bourbon County. I will say that there were a surprising amount of different variations of Grapefruit in beer. Hmm… I wonder where everyone got that idea from… 


The festival was two days, and one of the top Michigan beer culture events. It was estimated that there were over 10,000 people over the two day event. There were people in traditional German clothing, their favorite brewery shirt, and people wearing gigantic pretzel, beef, and cheese necklaces. Even people tempting me, walking around with big soft pretzels on a stick. 

If there is one thing I will be taking away from my first Perrin Brewing beer festival, it would be that I love the atmosphere and will definitely be attending more in the future. I hope to see everyone there!

Greetings Perrin People! Beer Week Secret Stash!

From Brewer Adam LeClaire


Greetings Perrin People, 


As you may or may not know, May 11-17 is American Craft Beer Week and that alone should get you excited. As I write this, we have 23 different beers on tap in the pub (with a few more returning favorites waiting in the wings) - but we know that isn't enough. We know that the public demands more, so any chance we get we are either filling barrels with beer that the bosses don't know about or stashing kegs of specialty beer for a rainy day. So now, in honor of Craft Beer Week, we're opening up the secret stash and unleashing this goodness upon you. Monday through Friday we'll be tapping one special offering each day. Here's a quick peek at the beers we've been hoarding away for you and when they'll be available:


Monday 5/11 - Juicy. This beer is essentially Grapefruit IPA on steroids, but we also brewed it under the super-moon to effect the gravitational pull of the hops on your brainwaves.

Tuesday 5/12 - No Rules. Sometimes John goes a little crazy and he makes a 15% porter with coconut and cinnamon.

Wednesday 5/13 - Bourbon Barrel Aged Sweet Potato Porter. We took a silver medal winner at this year's World Expo of Beer and aged it in oak barrels.

Thursday 5/14 - Rye Whiskey Barrel Aged She's So Wee Heavy Scotch Ale. That's about the longest beer name ever - and a nice scotch ale aged in oak.

Friday 5/15 - Oak Barrel Aged Kona with Chestnuts. Just like the name says: our coffee brown ale aged on oak with chestnuts. 


In addition to all that beery goodness, we're also giving you a few chances to check out the brewery. We'll be running tours on Saturday and Sunday, so if you've ever had any interest in getting past that big glass window - here's your chance.  

'Lil Griz: Brown Ale Aged in Oak Bourbon Barrels... an editorial.

From Perrin Brewing Brew Team Member, Justin Stewart:

Every beer has a personality. 'Lil Griz has a certain je nais se quoin about it. That's French for malt forward sexiness. Underneath a flavorful bourbon mouth-feel, a smooth velvetyness starts to emerge and 'Lil Griz shows its' true personality. It says, "Even though I CAN grow facial hair (and that in NO way defines you as a man) I choose not to!

Come and enjoy the 'Lil Griz draft release tonight (April 10) at 5 PM.



Dear Roeselare,

… We know our sours beers are good but it may be too early to start writing love letters about them, well at least wait until Friday when Roeselare is released! Roeselare is a Flemish Amber Ale that uses a mixed blend of Flemish Red and Roeselare yeast strains which have multiple types of wild yeast: lactobacillus and pediococcus and it is named for the Roeselare region in Belgium where these wild ales originated. It has been aged for over 1 1/2 years in neutral barrels which makes it a complex sour. We are excited for the release as it has already gotten high esteem (links will be shared when articles are released). Roeselare will be available in 12 oz. bottles.

 We have a Belgian Brown sour being aged in Cooper barrels with a large addition of Michigan’s King Orchards’ Montmorency cherries. This is another exciting part of our growing sour series! Hope you enjoy! Cheers!


A sneak peek into two of our upcoming beers; a Pale Ale and Sweet Potato Porter.

The Pale Ale is a 4.6% ABV 40 IBU brew that is heavily dry hopped with Mosiac and Motueka hops. Mosiac hops are one of the most sought after American hops that offer a high amount of aroma and a citrusy, fruity pebble, mango like taste. Boosting the aroma of this Pale Ale even more so are the highly aromatic New Zealand hops Motueka. Overall this Pale Ale is extremely aromatic with a light body and a crisp finish. This beer is being released the first week of February. Seeing how over 70% of what we taste comes from the sense of smell this beer is sure to be tasty! 

 Have you ever thought about putting your favorite porter into a blender with a holiday sweet potato soufflé to get the best of both worlds? Well since that is unadvisable we went ahead and did the next best thing and brewed a sweet potato porter. This was a collaboration between the brewers and Perrin Brewing Company’s own kitchen staff! Kitchen Manager Marc Perkins along with the kitchen staff candied 160 lbs. of sweet potatoes for us to use in our brew. The potato starches will lighten the body and we added lots of low level crystal malts and carapils to sweeten the beer and add caramel notes to create a candied potato porter. Our production manager has been tempted with garnishing the pints with roasted marshmallows... The specs are 5.41% ABV and 33 IBU and it will be available in March.
