100g Tub of Irish Moss for use in homebrew beers

Brupak Course Ground Irish Moss Carrageenan / Chondrus Crispus Home Brew Beer 100g

Irish Moss is red-brown flakes of seaweed (Chondrus crispus)

The active compound is the polysaccharide Carrageenan that carries a negative charge that interacts with proteins to form large flocs. 

Brupaks Irish Moss Copper Finings allows the brewer to create a brighter worts by assisting the coagulation of unstable proteins in the copper and rapid settling of the coagulum as hot and cold breaks. 

It is vital to produce consistently bright wort by reducing the amount of protein and polyphenols. 

If high levels of protein and polyphenols are present, they will lead to draught beers that are difficult to fine or bottled beers with a much-reduced shelf life. 

While some proteins can be removed with auxiliary finings, it can present other problems. This can be improved considerably by its removal in the copper.

Method of Use 

Irish Moss should be added to the copper 15 - 20 minutes before the end of the boil. This is to ensure that the active carrageenans are extracted.

Dosage  

Dosage can vary considerably dependent upon many factors including grist composition, wort gravity, pH and seasonal variation in brewing materials. Typical rates of addition are within the range 8 – 25 grams per barrel (5– 15 grams per hectolitre). The brewer should assess by trials the additions required to optimise performance and costs. 

Storage  

Brupaks Irish Moss Copper Finings should be stored under cold, dry conditions in tightly sealed containers.
