So, I'm a beginner, but this isn't my first batch. Everything I've brewed up until has foamed nicely and bubbled in my airlock like it's supposed to. I had some friends taste my cider and they loved it and asked if I'd share some, so started 4 gallons (all in 1 gallon containers) and followed the recipe the same way I had initially. I did 1 gallon first (all made from Whole Foods Apple Juice) on a Thursday and it started out nicely. I went ahead and did the next 3 gallons on the following Monday and none of them are foaming at all. They're bubbling a bit (not super fast, but not snail's pace either) but they're foamless. they've been sitting there like this for just shy of 2 weeks now. My recipe calls for halting the brew at 2 weeks, think they'll be ready? or should I do something else?
