I started a coffee wine and the yeast seemed to be rocking more than normal.

Has anyone noticed this before or are my yeast just pulling college all night study sessions? They seem to love coffee.

I never tried coffee with brewing, but I used to grow mushrooms, and they seemed to like coffee grounds. maybe same kinda thing going on.

My wife and I did a Chardonnay/semillon kit and added a handful of coffee beans in secondary. Turned out great!

I did a quick bit of research and apparently caffeine extends the lifespan of yeast cells quite a bit. Maybe you have a much higher amount of yeast cells on your fermenter than usual?

HELL YEAH, that sounds awesome!

Caffeine and possibly other nutrients in the coffee beans are helping them out, I'd say.

haha it's WINE ROIDS

Following this one, definitely - tell us out it turns out! Were there any other ingredients besides coffee and, I assume, grapes?

Not necessarily. If he's using Jack Keller's recipe...
winemaking: requested recipe (Coffee Wine)
...then he won't. Grapes would help provide nutrient, but if a recipe by Jack Keller DOESN'T list grap concentrate or raisins, there's probably a very good reason for it, seeing as most of his recipes do. Probably the tastes don't go together.

Will the wine have caffeine in it?

Pith

Yep. I can't think of any reason it would break down.

I used the Jack Kellers recipe with a flavored coffee. I plan on throwing in a handful of coffee or espresso beans into the secondary.
