Gah- I tried to post an article from Huffington Post that describes the Red Delicious apple and how it got the way it is, but the link didn't work for some reason so I deleted my original post. Let's try this:
Starkrimson® Red Delicious Apple from Stark Bro's
This might be an improved version of it, but evidently this variety is known to be beautiful and crisp, but not so tasty. The Huff Po article mentioned how, just as many varieties of tomatoes grown for grocery stores were bred to withstand being shipped long distances, and good taste was lost, Red Delicious was bred to be attractive- and most of its flavor went by the wayside in the process. (The writer said this type "sucks", which I think is a bit harsh- I do eat RDs every now and then.) The article also mentioned a personal fave of mine- Empire- and a variety I haven't tried yet but just picked up at the Farmers Market today: Winecrisp.
