Just a note that I was very happy with the Hansen CH16 dry ML culture -
I had several carboys of 15-16% Petite Sirah with ML stuck in various
stages. All of them are now finished, in less than a month after adding
the culture. I had to add it twice - first time dissolved in small
amount of wine but that didn't work; the second time I used the dry
culture directly, that worked like a charm. For some reason, there were
no visible bubbles coming up for some reason, only a ring of them in
the neck of the carboy...?
