Irish Moss is a seaweed derived fining agent used by many brewers to help make a clear beer without the need for a filter, and to prevent chill haze. Irish Moss accelerates protein coagulation during the end of the boil which helps prevent chill haze. Many of our brewers use this product in every batch. Use 1 teaspoon per 5 gallon batch, and it is added with 15 minutes remaining in the boil.

This is about as inexpensive and in terms of flavor least invasive way to make your beer more clear. Sometimes though one has to wonder if it really does do anything at all.

Gets the cold break out of my wort
It causes the cold break to congeal and fall to the bottom where I can leave it in the kettle after the boil.

I used a small amount of Irish Moss in my 1-gallon brew, and I found that there was more sludgy sediment than usual at the end of my cooling phase. Should I pour that sediment into my fermenter, or should I discard it?
A shopper on Apr 12, 2018
BEST ANSWER: Discard it. You use Irish Moss as an agent to bind with and sink these particulates to the bottom, as trub, to clear your wort and keep the flavors from becoming tainted..
What type of seaweed is this derived from?
A shopper on Mar 8, 2018
BEST ANSWER: I can't answer your question. I doubt if most brewers could. And, respectfully, I'm not sure that it matters. You won't consume it because it will fall into the trub and be discarded. Its purpose is to attach to proteins and other ingredients that cause clouding and off taste and cause them to fall out. It does that very well. I realize that this is not responsive, but I hope that it is helpful.
Is this recommended for use in a wheat style beer or is the cloudiness it traditionally carries desirable?
Colby F on Oct 29, 2017
BEST ANSWER: While Irish Moss helps to clear most Ales I don't think it will clear up a wheat style beer, I'm not sure anything short of massive filtration will totally clear a wheat brew.
It couldn't hurt to use a teaspoon and certainly no cost to worry about... Good luck.
How many teaspoons would be in a package?
B A on Jan 28, 2016
BEST ANSWER: I haven't used it yet but I want to say about 6 possibly
