No, I added some ascorbic acid to this batch. I have several batches going now, but this is the oldest. The problem is that it's going to take a year to determine keeping qualities if it's any good. Much less, of course, if it's not. I'm hoping that a time history of some number of tests from the same batch will show a trend before a year.
