Hey All,

A philosophical question as it were. I brewed an Oktoberfest today but the recipe called for Irish Moss. Now, would adding Irish Moss to a batch of beer push it outside the bounds of the Reinheitsgebot?

Short answer: yes, it will be outside of the bounds.

If a recipe calls for something besides barley, hops, water or yeast, it is not Reinheitsgebot compliant. That does not in itself make it a bad recipe, just not one that follows the purity law.

For Reinheitsgebot purists, the addition of kettle coagulants is not allowed.

Irisher Muss ist night drin das Reinheitegebot.

This is one reason an O'fest is brewed in March...with cold storage (lagering) all summer long all the yeast falls out resulting in a clear brew.
