I'm so excited to post outside of the beginners' forum!!!!
My next baby is going to be an all grain stout (no, I haven't decided on the exact recipe yet). To get both a coffee AND oak flavor, I'm thinking about soaking 1-2 oz. of oak chips in 1-2 cups coffee liqueur (something like Starbucks at 40 proof) for maybe 7 of its 20-40 days in primary.
First, is 40 proof enough to sanitize the oak chips? And second, is this a stupid waste of 5 gallons of otherwise tasty beer?
Okay, thanks for any help. Back to my first beer...my crazy arse IPA.
