I bought some Munton's Carb Tabs to carbonate one bottle in order to experiment with spicing levels in a Pumpkin Ale. The tabs worked great! Fully carbed in 3 days. It's a little more expensive, but with better control over carb levels, I'm considering using them for a full batch.
My question is: normally you boil the priming sugar to sanitize it, is that an issue with the tabs, or are we just taking an acceptable risk that they're clean?
