KENNEWICK — A new apple under development at Washington State University could compete for the hearts and palates of fruit lovers in a few years. It’s burgundy red and juicy, and compares favorably with the popular Honeycrisp variety, with the same kind of crispy crunch. It doesn’t have a name yet. Researchers simply call it “WA 38.” But in taste tests conducted by the university, some consumers prefer it to a Honeycrisp apple. WA 38 has a nice sugar and acid balance, researchers say. It’s very sweet, but with a “good kind of punch of tartness,” and gets its texture from Honeycrisp.
