Product Description

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. Use 1 teaspoon per 5 gallon batch, and it is added with 15 minutes remaining in the boil.

5.0 out of 5 stars It is great for brewing

One teaspoon in the last 15 minutes of your boil is all that it takes to get amazing clear beer. Numerous authors have described how it works, no need to go over that here. It may smell awful, but will no effect on the smell or flavor of your final brew; it is used for aesthetic purposes only, so you can take it or leave it but I like to use it.

I used this as a fining agent when brewing beer. It works pretty well, as it binds with proteins floating around in the wort, and will yield a clearer brew when finished.

However, I have read about (and actually met a few people with a) sensitivity to Irish Moss (Carrageenan). It is similar to gluten sensitivity. I still use it, but you may want to look into it if it concerns you.

Haven't had a chance to try it yet but many homebrew experts swear by it for clarifying beer more quickly. The price was right and it sure can't hurt anything. I'll update if my opinion changes after I put it to the test.

works great, I typically add a couple of teaspoons to the last 15 minutes of a ten gallon boil and when I pump to my fermenters the coagulation of some of the break material starts right away. in the end my beers always drop crystal clear.
