I am 3 days from bottling and airlock still showing bubbles every 20 seconds or so. If the fermentation process continues, should I not add sugar to the bottling bucket to prevent too much pressurization, ie Bottle Bombs?
If there is still fermentation you aren’t ready to bottle no matter what a recipe says about a schedule. Check with a hydrometer.
Bubbles don’t necessarily equate to fermentation. Take a gravity reading.
Take two gravity readings, 3 days or more apart. If gravity drops, it’s not ready. (Or if gravity isn’t in the expected range on the first sample, it’s not ready - don’t bother with a second sample yet.)
