Many have achieved unheard of levels of alcohol content by distillation and adding more alcohol to the finished product. That’s easy.
But we brew. This project, undertaken only once every four years, tests our skills, our endurance, our patience, and our faith under pressure by pursuing a lofty goal—brewing our highest abv beer ever—22%—using only fermentation. This is the story of Colossus.
Three grains, two different strains of yeast, locally produced honey and hops, coriander, orange peel, and a mountain of pure sugar will be blended with the dexterity and grace of a sculptor to create a beast with the power to level mountains, yet remain in balance on the palate. It’s not as simple as blend until tasty…
Like all beer, Colossus begins with malted grains. The shells are cracked in a mill to allow water to reach the starch inside, causing the enzymatic reaction that creates simple sugars that the yeast will consume to produce CO2 and alcohol.
Yeast are microscopic single celled organisms that consume sugar and produce alcohol and CO2. The trick behind Colossus is to keep the yeast working as the alcohol around them builds to a concentration that is normally far too toxic for them to survive.
The yeast must be fed, as the simple sugars from the grains will not keep the yeast working long enough to produce a colossal abv. Pure white sugar, 3200lbs of it, was fed to the yeast in 64 sessions over a period of 8 weeks to keep the beast fed, the yeast working, and our dream alive.
By testing the gravity of the beer with a hydrometer, and using a mathematical formula that converts the hydrometer reading into the measure alcohol by volume, we charted the progress of the abv as it grew. This data was crucial as it was our only guide for when to feed the beast and when to wait. The exacting, time intensive process took 62 days from start to finish.

While still perceptively sweet, Colossus 2014 is less cloying than its predecessors, with vibrant flavors of apple and peach accented by notes of cinnamon, and balanced by its monster abv. But how high is the abv?
In early August, without warning or explanation, the yeast abruptly stopped
fermenting the sugar at an abv of 17.3%. It was a humbling reminder that despite all of our knowledge of brewing science, all of our painstaking attention to the craft, and all of our previous success, we are still at the mercy of tiny, single-celled organisms with no agenda.

Size still matters; but a highly flavorful, more drinkable, 17.3% abv Colossus is by no measure a failure, and there was no shortage of celebrating when we finally tasted the finished product. While we may not have built a bigger beast, we definitely built a better tasting one! 22% abv or higher remains the goal, but we’re confident that you will love Colossus 2014 as much as we do… at least until 2018, and our next attempt at defying gravity.
