With seven varieties appearing for the first time this year, and only four retirements (and the return of Wickson), the score at farmers market this week rose to twenty-five different kinds of apples. (Photo: An embarrassment of riches at the farmers market in Belmont, Massachusetts, earlier today. ) The local markets are just the tip of the apple. As of this writing, Volante Farms, a Needham farm stand, is reporting 23 varieties , including 11 not at farmers market. Shelburne Farms, an orchard in Stow, reports a staggering 38 kinds of apples , some in the store, some on the trees for picking, some both. (Note that things sell out.)
