We have had an unusually warm/hot summer this year, until about two weeks ago, when we had about 3 days of very unseasonably cool weather (20 deg below normal), and we are now back to warm, "Indian summer". A couple have finally gotten better, but not all.
Interestingly, Black Madeira continued to ripen through the cool weather, and still tastes very good. Normally, after the first few cool days, it stops ripening, and when it warms up it resumes, but never develops really rich flavor the rest of the season. Labor Day weekend, we had three days well over 100 and I am wondering if that spike initiated the ripening process in such a way that it has kept it ripening. Another part of an unusual year. Oh, more Black Madeira is always a good thing!
