I am new to this and I've always wanted to do it, but was a bit intimidated, so I didn't. I have several orchards nearby with lots of fresh cider, so this year I told myself it was time.
I've got two 5 gallon batches going and the first batch has been going 24 hours and the second batch I just did around 8pm EST.
The first batch had a nice krausen going, but it seems to have dissipated and now there are bubbles/foam on top. I was nervous it was starsan because it looks just like it, but the more I read, I don't think that's the case. So... are the foam/bubbles normal?
Second question, how long do I let it go in the primary before I start taking some gravity readings? I don't want it to get bone dry on me, but at the same time, I don't want to chance spoiling a batch by messing with it more than I have to.
