    I have seen powdered and unpowdered irish moss. My question is does one work better than the other? and whats the conversion. like how much of one is equal to the other?

    I don't know. I just use a whirfloc tablet. Does the same thing, one tablet per 5 gal batch. Drop it in at 15 min mark and that's it!

    Thats more the powder version. I bought like the grinded up/ crumbled looking stuff and put it in at the 15 min mark. Guess I'll find out soon how well that works.
  4. I use Irish Moss flakes in my homebrewed beers. I have never used the powder form so I can’t comment about powder.

    I rehydrate my Irish Moss flakes and add them with 15 minutes left in the boil. My homebrews come out nice and clear.

    how do you rehydrate them?
  6. I just add 1 tsp into the boil with 20 minutes left. I have never heard of rehydrating irish moss and don't know if it's even necessary.
  7. From Al Korzonas’ homebrew book:

    “The Irish Moss should be rehydrated in a cup of clean water for 12-24 hours and then added in the last 15 minutes of the boil. If you forget to rehydrate it, go ahead and use it dry, but it will make a bigger difference if you rehydrate it first.”

    I have just rehydrated for the duration of the boil (about an hour) and that seems to ‘work’ fine too.

  8. If you are happy with the clarity that you are getting by pitching the Irish Moss dry then the ‘answer’ is that it is not necessary to rehydrate the Irish Moss.
