Hello. I have a American Pale Ale batch in a 6-gallon carboy that I brewed BIAB style. It was my first time brewing this way, so ended up with only 4 gallons instead of my target 5 gallons. It has been in primary fermentation for one week today and I noticed that fermentation has come to a halt (at least visually, no bubbles coming up the air lock, kreusen foam settled down). Can I go ahead and package the beer, or do I need to leave it in fermentation longer? If longer, then do I need to reactivate the yeast? Thank you in advance for your time.
