I have potassium meta and some One Step. Both say you don't have to rinse, I keep wondering about that every time I stir my must with a spoon that's been dipped in one or the other.
I agree I have wondered about that as well. Now I know. I think I have settled on the one step, so now I have to track some down.
Thanks, not going to worry about that anymore. Also, I don't know about our tap water here either. Sometimes I think I smell chlorine in it even though they say they don't chlorinate it, so I've never used it to make any mead.
I filter my tap water. I swear I smell chlorine in our water too, and my husband assures me it's not there.
