Does gelatin work for clarifying beer? If so:
- How much do you use?
- When do you add it?
- How do you prepare it? (Do you boil it in water? How much water to dissolve the gelatin?)
Gelatin is used post fermentation. Irish moss (and whirlfloc and supermoss) go in the boil.
Sometimes you can get a bit of yeast or chill haze even with kettle finings. At that point you could try gelatin to fix it.
Don't boil the gelatin - that makes jello. Instead, boil 1 cup of water by itself. Take off the heat for a minute or so then whisk in 1 packet of unflavored gelatin. Then add that to your fermenter or keg. You may notice some improvement in 24 hrs, but it usually takes 3-4 days to completely clear for me.
It should work. Winemakers use it as a fining agent.
A more common fining agent used by homebrewers is irish moss, added during the boil.
