Google AI says there are up to 39 sports of Winesap. Before CA storage it was widely grow due its long storage life under regular refrigeration. So plenty of opportunities to find sports.
I have gotten Winesap apple from many of the Virginia orchards in recent years. None have surpassed the particular Winesap that Vintage Virginia Apples grow. They are very dark all over and picked later than other orchards in that area. Hopefully the young trees I bought from them will be of the same quality and flavor in my location. I have several other Winesaps including OFW, Red, Double Red, and Black to compare in a couple of years.
