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.

Amazing addition to my brewhouse
I was skeptical about using this at first so I did what any skeptic would do. I bought two of the same kit and did one with and one without. I added this during the last 15 minutes of my boil and within 72 hours in my primary fermentation the difference was highly noticeable. The beer was not near as cloudy as the no addition batch. A side by side comparison was night and day difference. Even in secondary the one with the addition had a significant amount of less haze and the gold color of the honey wheat beer was showing bright as can be.
It didn't come in a bottle, but in a bag but either way I don't mind and will never go without this addition ever again. Even my dad was surprised at how clear the beer was on comparison. The flavor comparison was unfazed by the addition too.

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: Chondrus crispus—commonly called Irish moss or carrageen moss (Irish carraigín, "little rock")—is a species of red algae which grows abundantly along the rocky parts of the Atlantic coast of Europe and North AmericaEnter an answer to this question.
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
