I brewed a White House Honey Porter last thursday evening, my first ever brew. The fermentation was up and running by the next day and I could hear bubbles in the bucket the blow off tube was in. After 2-days, however, the bubbles stopped and there’s no sign of activity within the glass bottle. There’s no krausen on the top of the beer and there’s a thin layer of sediment on the bottom of the bottle. Should I give the beer a gentle stir? Perhaps it’s still fermenting but just not bubbling?
