Irish Moss


If brewing clearer beer is your goal, try Irish Moss! A kettle fining derived from seaweed, and a major source of carrageenan that is used as a clarifier in home brewing.

Irish Moss enhances cold break (protein coagulation) in the kettle for clearer beer. Essentially, it pulls proteins and small particles out of suspension during brewing for a clearer, less hazy finish.

Recommended dosage is 1 teaspoon per 5 gallons. Add on brew day with 15 minutes left in the boil. For best results, rehydrate for 10 minutes in a small amount of cold water before adding to the kettle.

Interested in other clarifiers? Try Whirlfloc Tablets, which are essentially Irish Moss in tablet form & don’t require rehydration. Or try Gelatin Finings, which are added after fermentation and can be used in combination with this product.

Package contains 1 Oz of Irish Moss.
