I've got my first 5 gallon batch of cider into its 6th day (Ed's recipe). It has been fermenting nicely for 3 days in a 6 gal carboy. I don't know if there's a way to rate the fermentation activity, but it's been going at about 30 burps or bubbles a minute. Until today. It has slowed to 10-12 burps a minute. Maybe I'm watching it too closely because I'm over anxious, but is it expected to slow down so quickly? I feel sorta like a mother hen worrying about her chick.
