I got this kit for my birthday. I’ve never used a couple of the ingredients in this recipe before…Costa Rican cocoa husks & cocoa nibs, and lactose (milk sugar). Sounds good, though! While doing some reading, I came across information regarding hazelnut extract…I’m thinking Nutella Stout. After mulling it over a bit, I decided to skip the trip to the brew shop for the extract because I thought it might just get to be too sweet and might not taste natural.
After some more thought…and realizing that I had a bunch of whole bean coffee on hand that I got on sale…I started looking into using coffee as an additional ingredient. Natural, not adding more sweetness, adding caffeine and making this recipe a “mocha”. Yup. That’ll do! So, I sent a message to some local brewery people for advice. They suggested making a cold brew coffee concentrate and using about an 8% by volume at bottling. I never would have thought of that! I’m actually going to go about 4 cups of concentrate, rather than 6 cups…I can always add more, but I want the chocolate to still come through.
I found a cold brew coffee recipe online from Bon Apetite (giving credit, where due!). I adapted it to brew in a gallon carboy with an airlock, instead of some other container covered with cheesecloth. I coarsely ground 12 oz of Kona blend coffee and added it to a sanitized carboy and capped it.
Shook it up and swirled to get as much of the grounds off of the bottle as I could and then replaced the cap with a sanitized airlock. After 15 hours at room temperature, I’ll strain out the grounds and then filter the liquid through multiple layers of cheesecloth. (If I were concerned about it being crystal clear, I would filter it through a coffee filter…slowly. I think going through a sieve and then through thick cheesecloth will be fine.) I am going to use a teaspoon of Irish moss in the boil, just to help the beer clear a little, but I’m not expecting to see through it…it IS stout, after all.
So, what I’ll be brewing will be a “Costa Kona Mocha Milk Stout”. I’m sure I’ll be sampling it as soon as I can, but I think this one might need to age until next December-ish. I think the caps that came with the kit are the “oxygen absorbing” kind…good for longer storage. Brew Day tomorrow, if I can fit it in!
