Gelatin’s effect on flavor in homebrew beer
Mike had heard on a podcast or video that gelatin can strip some of the flavor from homebrew, and he wanted to find out. Well, it just so happens he just brewed up a big old batch of Kolsch, and split it off out of the fermenter into two separate kegs. Then treated one with gelatin. As you probably know, a Kolsch is a fairly delicate beer, and we figured that if we could taste a difference, the Kolsch would be the best bet for doing so.
The recipe is linked below if you’re interested in giving it a go, but keep in mind it’s an 11G batch. The next go around, Mike may add something to help with the head retention.
What were the results? Well watch the video and see for yourself. 😊 What are your thoughts on gelatin’s effect on beer flavor? Let us know!
We wrap up the experiment pretty quickly, and to be honest, the last 12m of the video is chit chat on various topics, other videos we have in the pipe.
Shoutout to @ApartmentBrewer for his Beer Engine videos. Mike picked on up and has been relying heavily on it.
