Meanwhile, we had purchased some Old Orchard apple juice for a recipe we were doing. It was very delicious with a totally different flavor profile than the Louisburg Cider I have been using. It's pasteurized, so no preservatives to get in the way. It's from concentrate with added malic and ascorbic acid -- no biggy. It's a little less sweet, a little more tart and more full bodied. It is also noticeably darker than Louisburg. I checked and they both have the same calories and carbs, so I guessed the same amount of sugar. But it OO was just better tasting, so I fired up a 1-gallon batch using my favorite yeast from the 3-yeast test.
I took the initial specific gravity and TA and it came in about the same as Louisburg (1.048/0.3), so the same sugar and acid. Interesting, because that's not my impression tasting it. That just goes to show there's a lot more going on than the two things. I adjusted the acid up to a more tart 0.6 and added some wine tannin to get to my targets.
I started the fermentation about a week ago, and transferred to secondary this morning. It smells absolutely fabulous at this point, so I am very optimistic.
Note color difference from previous batches with different juice:
