Can I leave my cider in the Primary for up to like 4 months with no need to rack it?
I am wondering the same thing. I am moving across two states over the summer and have a wine going - should I try to transport or leave for 3-4months?
It really depends- if you have lees or dead yeast on the bottom, you should rack it. If you don't, no problem.
Well, mine started around 1.090 and its down to 1.040 - on lees with plenty of time to go still. I'm only making one gallon in the cider jug so should I just throw on a cap and make sure it doesn't get too pressurized?
No, at 1.040, it's not done. It needs an airlock for co2 to escape. Can someone refill the airlock if it evaporates? You just need an airlock, and it'll be ok.
Well, I wont be able to help figure this out. The cider has made the trip with me and seems to be fine (maybe a little more than fine if a bit of the vodka from my airlock made its way in).
