I've switched to a 6.5 gallon carboy for primary fermentation (had been using a 5), so I'm not concerned with blowing off krausen etc. I'd like to do away with a blow-off tube, and just use an airlock from the start. But both of the last two batches I've done in the 6.5 (ESBs) had VERY rapid fermentation -- bubbles-per-second were so quick that they practically couldn't be counted. No temperature issues or anything that...in fact, both came out great (almost wish I had entered into a contest!). I'm concerned, though, that the amount of CO2 that was produced would have popped off a standard airlock. Is there an airlock that will allow a greater rate of CO2 to pass through it without popping?
Thanks!
Thanks!
