I had an issue trying to find out how much to carbonate my last batch, and it ended up not being carbonated (after all that time waiting!). So I'm thinking it might have been my caps, first time I used caps, normally I do it in a Grolsch bottles. The Grolsch ones turned out ok, but the CO2 was still low. Could have been my $3 scale too that I used to measure the sugar with too. Anywho, does anybody know what the max amount of CO2 you can have in a bottle before it explodes? I think I got too concerned over measuring out exactly how much sugar. Just wondering how resilient glass bottles are haha
