calyx. My sample has some russet in the stem well and a mellow aroma that suggests pear and Golden Delicious.
Pristine's flesh is tender with a little snap, a coarse light yellow. The balance tends towards tart, with lemon, pear, and vinegar notes. These pretty little apples taste as bright as they look. There's a nice astringent finish. I think Pristine would make a sophisticated accent in a salad of greens.
According to the breeders of this apple, Pristine ripens a full month (or more) before I bought mine on September 2. I'd like to to try these right off the tree some year.
Update: I did and they are great; details here.
