Hey ya'll, I signed up yesterday and this is my first post, but I've been lurking and I've learned a lot already. Anyhow, I want to try a SNA on a metheglyn I'm starting, but when I went to my brew store they only carried potassium bicarbonate (KHCO3), not potassium carbonate (K2CO3) as called for. Anyhow, I saw on Wikipedia that above 100c, KHCO3 will decompose into potassium carbonate. Looking at this reaction: K2CO3 + CO2 + H2O → 2 KHCO3 , I'm guessing i should use about twice as much KHCO3 by weight, or 10 grams for a 5 gallon batch, and boil it. Does anyone have any better advice for this?
