A lot of the homebrew I make is made with organic ingredients - organic grain and hops. However, I have never come across organic yeast (!?) or irish moss. Can I rightly call this beer organic, or does the addition of yeast and irish moss relegate it to "beer with organic ingredients"?
Most organic products are not 100% organic. Compare organic carrots to organic carrot cake. The FDA or USDA has allowed that a small percentage of the ingredients not be organic as long as the primary and majority ingredients are organic. There are several organic beers out there that don't use all organic hops, yet the still retain the organic label.
I am sure your beer is organic enough to tell your friends its organic.
