How to use Whirlfloc tablets when brewing

whirlfloc tablets brewing
It's always amused me that people think it is OK to add moss to beer.

I mean really, how the heck can Irish Moss clear beer?

It's not even real moss, it's an algae from the sea!

Which makes m then wonder who the heck discovered that adding Irish Moss as a fining agent for beer?

Anyways, work the moss does.

A popular form of it is the Whirlfloc tablet which is a blend of Irish Moss and purified carrageenan ingredients. Carrageenan is another extract from seaweed that is used for gelling, thickening and stabilizing properties. This is because it bonds to proteins which means it is just perfect for brewing and removing proteins and so-called 'beta-glucans' (sugars) at the end of the boil.

You can use Whirlfloc tablets as a clarifier for both extract and all grain brewing.

Your instructions for use are simple.

If you are doing an all grain boil, you add one tablet per 10 gallons when you have 5 minutes left in your boil. If you add any earlier, the boiling of your wort will destroy the ingredients ruin their effectiveness.

If you are using an extract kit for either beer or cider, you can add the Whirlfloc when fermentation has completed.

If you are wondering whether Whirfloc tablets actually do work, here's an experiment which proves they do improve beer clarity.

There are plenty of other ways to clear beer with finings. There are other fining products such as Chillguard and Polyclar and silica gels like Kieselsol but if you are a bit of an expert, you can actually filter your beer but you'd need to be kegging it. Cold crashing is always a good way to get rid of proteins from beer as well.
