The Kollusion Kollaboration

From-Kevin“Why would two different brewers stick their mash paddles into the same pot?”

This was a question posed to me by a Dutch brewer in a small enclave of Belgian territory about 5 years ago. That has been my thinking ever since regarding collaborations. They almost always come across as a marketing gimmick, despite the positive reaction from the public.

My mind was changed however, on our last trip to Belgium as I had the opportunity to visit one of my closest brewing buddies in Belgium, Thijs Maenhout of Brouwerij Maenhout. Thijs’ brewery is similarly sized to that of Boom Island. 12-15 BBL batches, unfiltered and bottle conditioned as is consistent with Belgian tradition. Thijs’ brewery is unique in that it qualifies as a genuine “Huisbrouwerij” under Belgian law meaning that his family’s place of residence is under the same roof as the brewery itself. The thing I most respect about Thijs though, is a quality I strive to execute here at Boom Island. That is nailing down the classics of the Belgian tradition of brewing first, then stepping beyond that realm to show one’s true understanding of the broader brewing culture.

On that last trip to Belgium, I was lucky enough to meet up with Thijs over a few brews as he casually tossed out, “Why don’t we do a collaborative brew of some sort?” Having never approached the topic before and without hesitation, I responded, “Absolutely!”. So what follows is how it all went down.

He chose the style, Russian Imperial Stout. I added the idea of using a bit of Chocolate to represent Belgium and a bit of Coffee (supplied by North Loop Dunn Bros.) to represent Minneapolis’ vibrant coffee scene. Both ingredients to be kept subtle and balanced as should be in true Belgian fashion. From there, Thijs developed a recipe and sent us the samples via a friend who happens to work here in Minneapolis a couple of weeks each year and also happens to be his logo designer. The entire Boom Island team agreed that test batch was outstanding! No changes necessary.

Then came the biggest challenge, naming the beer. Let’s see:  Russian Imperial Stout, behind closed doors, Belgian brewer meets with American brewer. No paper trail, no missing emails, no dossier, and until now no one has had to recuse themselves.   The name “Kollusion” surfaced, seemed perfect and was agreed upon


Kollusion –  Russian Imperial Stout, 11% ABV

Appearance –Thick and inky as a blackout velvet curtain, with a deep espresso head

Aroma –  Roasted malt, with hints of chocolate and coffee lurking in the shadows

Flavor –  Bold but light on the palate, with notes of dark malt, coffee and chocolate in equal measure.  Flavors emerge as the beer warms in the glass.

Kollusion is bold, beautiful and a little mysterious.  It is a delicious departure for us, and we are excited about it. See for yourself on Friday, February 23 at 4pm.  Another collaboration beer with Thijs is a distinct possibility that will be discussed in late April when we visit the Brouwerij Maenhout with our Boom Island tour group. On the 23rd we will have bottles for sale and will be pouring it as fast as we can get it into a glass.
