This fall I decided to brew a chocolate porter. The recipe was very similar to my already established porter recipe. The original Porter, was on the roasty and chocolate side and included a healthy helping of hops. The next step, for me, was to increase the chocolate taste profile. Being the nerd that I am, I wanted to change one variable and understand how it impacted a tried and true recipe. I fought over weather to increase the chocolate malt addition or to use a chocolate additive. After doing some homework I learned that everyone had pros and cons to each approach. Now, take those pros and cons and multiple them by 10 and that is the number of opinions on what chocolate additive to add. Finally the decision was made to use a chocolate additive. This was based on not wanting to try and brew with more chocolate malt in a partial extract brew in fear of losing valuable fermentable sugars in my small brew set up. Mainly due to the equipment I use to brew. So which chocolate additive to use? Imagine standing at Giant Eagle staring at the chocolate baking supplies and trying to decide on which to use. I swore a long time ago against coca powder because I believed it added a chalky texture to the beer and an unnatural dry mouth feel. So what do I do, I decide to use coca powder. Why?Well some high respected blogs swore by it over other approaches. From my limited understanding using milk chocolate or baking chocolate can introduce a fatty substance that could potential surround yeast cells not allowing them to eat sugars and poop ethanol and CO2. I value fermentation above a dry aftertaste. To combat my fears with using coca powder I decided to use less than all the blogs said to use and to limit the time the beer is in contact with the powder to a minimal.

The fun part was taking a growler sized sample of the chocolate porter and transforming it into the Bourbon Barrel Chocolate Porter. This was all done without harming any bourbon barrels. I used oak chips that had been soaked in bourbon for several weeks. The bourbon soaked oak chips were added to the growler of chocolate porter and maybe a little extra bourbon made it’s way into the growler, but not much. The growler was then left in the basement at about 35-45F for 2 months.
After 2 months it’s time to tap into the growler and test it. The taste test was done in parallel with the chocolate porter.
Appearance: Both brews were very dark with little to no transparency. The bourbon porter had little to no head with no lacing. The porter had a dark brown head and slight lacing.
Aroma: The porter had significant more aroma. It’s aroma was full of chocolate and roasty malt. The bourbon porter was dull to the nose. Thinking this is related to the poor head retention and carbonation.
Taste: The porter again was much more flavorful. The bourbon porter was a let down. It was a dull, muted, chocolate taste with a very very very fine hint of bourbon booze.
Mouthfeel: Both brews went down easy and had a nice feel. The bourbon porter had little carbonation and could stand to use more for a better feel and taste and aroma.
Overall: The chocolate porter turned out ok, still not a fan of coca powder and plan to change that in the new brew. The bourbon porter will also under go some updates. One of which will be the conditioning of the oak chips and the aging process in the ‘bourbon barrel’. I hope to use a different container where the beer and can have better surface contact with the oak chips and the bourbon. Thinking of using a keg and laying on its side or stealing a bourbon barrel. Know where I can find a bourbon barrel in Pittsburgh? Another change will be to do more homework and reference the Radical Brewing book.
This was a disappointment, but still fun and enjoyable. I’m excited to try out the new ideas and see how it impacts the final brew.
