I've experimented with a few.
Coffee basically created a strong as possible coffee extract with vodka a fresh ground coffee beans.
It worked kinda I had two issues....one finding a decent creamer(I dont personally do black)
and two after a few weeks instead of improving with age(like most juices)....it started tasting like stale left over coffee.
Chia Tea...was just ya. That was a mess. Tried doing and extraction like I had with the coffee...ended up with really fine sludge in it almost. Filtered it with coffee filter a few times....mixed it up about 20%. Taste was there...but it killed an atty pretty quickly. I didnt try that one again 0o. (I do believe PA now makes a chai tea, so no need for this now I guess)
