Pappers... you are the man! (assuming you are a man
my experience was favorable!
no sugars or addition in fermentation
2 cans of concentrate added before bottling (final gravity around 1014 i believe)
I filled one water bottle as a tester (squeezing the bottle some so I would know when it was bloated)
4 days and the water bottle was bloated and tight and the bottom was bumped out (thin plastic so i let bottles go another day)
cider gushed out of the top when I opened a tester at 5 days... good to go!?
I was able to fit up to 12 bottles in my boiling pot and the only issues I had were some bottles bubbled up from the caps. It turned out it was the stella bottles and woodchuck bottles I was re-using that didn't cap very well. only other issue was one of the flip top (grolsch) style bottles blew its rubber seal but disaster was averted since I had a lid on the pot.
thanks for these instructions!! I just did this tonight so I can't speak to the (hopefully) absense of bottle bombs.
