I started a 1 gallon batch of this last friday (3/17/17) using 3 quarts of tree top and 1 quart of the Just Black Cherry. This is my first time ever making cider, so we'll see how it goes.
I was planning on adding a little brown sugar to get the OG up but I was surprised when I checked the gravity of just those two mixed it was already somewhere around 1.060 (I didn't look too closely at it) so I just let it go without adding anything.
Pitched a whole vial of WLP060 and it took almost 24 hours before any noticeable fermentation started, but then it took off. Without a whole lot of headspace in the 1 gallon carboy it pushed quite a bit of gunk out the blowoff tube. Monday I switched over to a regular airlock. It's still bubbling about 3 or 4 bubbles a minute.
I'm looking for a slightly sweet, lightly carb'ed, bottled cider so I'm planning to start checking the gravity once the bubbles slow to about once a minute, aiming to hit about 1.010ish. Then add slightly less priming sugar than I normally would for beer (maybe use honey instead) and letting it bottle carb for a couple days (4 maybe?) then stove top pasteurizing. I will definitely try one before pasteurizing to ensure no gushers and that the carb level is about where I want it.
Anybody see any flaws in my plan? Thanks!
