DetailsIrish 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.

5.0 / 5.060 ReviewsMakes a good cold breakThis is good stuff, I add it, and immediately the egg drop soup cold break forms and the proteins start coagulating. This helps keep my beer clear and is easy to use and inexpensive.May 31, 2013Works wellIt's crazy how little moss you need to add to make a big difference to your beer. I have yet to crack open my first batch of bottled beer after using this stuff but I can see right through the bottle - which should be a good indicator that the beer OUT of the class will be quite clear. I'm impressed.June 25, 2013Love itHave used this every time since I received it. I definitely see a difference in clarity.July 14, 2013Protein CoagI have used the Irish moss a couple of times, adding it the last 15 min of the boil. I do, however, extract brew, but I think this makes a big difference in the clarity of my beer compared to not using it. You can immediately see the little clumps of "gel" (protein) at the bottom of the kettle at the end of the boil. A definite must if you are concerned with clarity. It is seaweed and smells like it, BUT it does NOT add or alter taste, so dont worry.July 16, 2013Less chill hazeWhen I started brewing I read that some brewers add this to every batch. It was cheap, so on my 3rd batch I gave it a try. I am on my 74th batch of beer now and still use this stuff in every batch. For the price, it would be stupid not to use it. It requires very little effort on my part and is very cost effective. It wont give you show quality clearness, but still rocks. Highly recommended!July 18, 2013Makes for a clearer beerThe Irish moss causes the proteins to clump together and settle into the trub. This results in clearer beer once its ready. I add it during the last 5 minutes of the boil.August 5, 2013Simple clarifierDoesn't make our brews "American" clear...thankfully. But it does cause much of the suspended solid to coagulate and fall to help create a more delightful, worldly ale.August 6, 2013Great value!This is an easy way to clear your beer. I use it in every batch.August 23, 2013Use it in every batchGreat product. I have been using it in every batch for the past year. With just one tsp. in each brew, I get a nice clear brew every time. I would certainly recommend this to everyone.September 2, 2013
