I have this kit sitting on the oak cubes as a final stage before bottling rather than when the fermentation is shut down, so I basically have the finished wine on the oak and can leave it as long as I like.
One concern with this kit is the low starting gravity. I measured 1.074. It finished at 0.993 for ~ 11% ABV. It's fine, I just expected a starting gravity in the mid-upper 80's.
What OSG did others get?
Mine started at 1.075 on 01/16/17 and finished at 0.998. I, too, was a little surprised at the starting gravity. It is currently sitting in the carboy for the last 4 week journey.
