Okay, Gotcha. Beyond my experience, but, as a start, maybe instead of ground, use some whole beans, sorta crushed (rolling pin, back of a skillet...) and instead of brewing, bring the lot to a boil and turn it to a simmer, leaving it there. It'll impart a better taste and help prevent grinds from getting into the mix.

Not claiming expertise. Just a thought.

It's nothing but coffee and brown sugar. The yeast I'm using is a dry champagne yeast that will eat all the sugar. At some point, around 11%ish, the alcohol will start killing the yeast. The champagne yeast is a bit more hearty and doesn't get killed so easily. I was looking at a potential of about 17% alcohol. Once it was done, I would've frozen it to finish off the yeast, then backfilled with brown sugar, cinnamon and pumpkin coffee syrup to her taste.
