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?)
  • If you add a space between the dash and your question you'll get a list instead of one long line. Jan 22, 2010 at 22:00
  • excellent, i was wondering how people did that...

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.

BYO question about fining

A more common fining agent used by homebrewers is irish moss, added during the boil.
