I made my first batch last night. Fermentation started somewhere between 4 and 11 hrs from pitching the yeast. When I checked it today at 11 hrs, there was vigorous bubbling in the airlock. Now at around 23 hrs, and bubbling has slowed considerably. I see a bubble once every 45 seconds or so. The krausen is still on the top so it is seems to still be going, just slowly. Is this a normal or did the bubbling in the airlock slow too much?
For reference I made a red ale fementing at 70 degrees right now.
Thanks for the help.
