I have about 5 gallons of regular nut brown ale (in the fermenter now) that I plan to bring to a festival. Since it is going to be served at a festival and folks will only be drinking 2 ounces at a time (and probably have decimated palates), I figured it should be very highly coconut flavored.
Rather than try to get a hop bag into the fermenter, my plan was to make a grain alcohol tincture with coconut flakes, then just add the tincture at bottling time. I would like to avoid pre-made coconut extracts because I would not feel comfortable telling people that's how I brew.
How many ounces of dried coconut flakes soaked in booze would it take to get a high amount of coconut flavor into this standard nut brown ale?
