Whirlfloc tablets are a blend of Irish Moss and purified Kappa carrageenan that encourages the precipitation of haze causing materials such as proteins and Beta glucans. Prepared in a quick dissolving, highly soluble tablet form. Almost everyone who tries Whirlfloc tablets prefer them to regular Irish Moss.
 
Add for the final 5 minutes of the boil. Note: One Whirlfloc tablet is good for 10-15 gallons of wort. We suggest using half a tablet for 5 gallon batches for most beers.
