I am leaning towards trying this with a 5 gallon batch of mead made with 4 gallons of liquid... (Then, adding 1 GALLON of freshly brewed gourmet - fresh roasted - fresh ground, etc. coffee during the first part of the cooling process....)
I am hoping the natural anti-oxidants in the coffee would not "kill the yeast" or anything....
I will definitely be experimenting with this concept... (Had to join this web site just because this thread showed up on a search engine...)
The reason for this approach would be that the HIGH HEAT of boiling messes with coffee... For excellent coffee you want the temperature just below boiling when you introduce it to the coffee grounds... (So no reason you can not boil the water first and then add it to the coffee to make sure it is close to sterile and does not introduce "nasties" to the mead...)
Being only 20% coffee it would probably make for a HORRIBLE cup of joe... (but I could definitely see people sensing a "hint of coffee" when trying to describe the flavor of the mead!! LOL)
I have my own coffee roaster and good sources for green beans... Right now I'm pretty weak on the "mead" side of things so I'd be happy to get together to work on this with someone who has more mead brewing skills to work on this concept... (I'm located in Apple Valley, CA)
