I’ve heard a lot about using gelatin to clarify beer, but I’m unfamiliar with the process. Can anybody help to shed some light?
I used to use it frequently. You just get the unflavored gelatin packs at the grocery, hydrate one pack in a cup or 2 of boiled/cooled water, and add. I’d usually add it to my keg at kegging time after I’d cold crashed the beer in the fermenter for a few days.
This method works pretty flawlessly, every time IMO:
I cold crash my carboy in fridge overnight. For 5 liters, I microwave 1/4 cup water 30 sec. Stir in 1/4 tsp gelatin. Pour in carboy and swirl. Let sit overnight and bottle. Works really well. I rack straight from my carboy to bottles. The gelatin besides clarifying helps to trap the yeast and trub some.
Yup, that’s the method that works for me too.
One additional point, It’s best to get your beer chilled to below 38*F before adding gelatin. That’s where chill haze proteins come out of solution and the gelatin can grab them and settle out.
Yeah, and I think he mentions that in the article. It definitely helps to have chill haze in suspension when you add the gelatin.
