Shubinka

Shubinka 

a very old Russian variety of cherry. The fruits are small and dark red; the firm flesh is somewhat tart, with a bitter astringent aftertaste. Shubinka cherries ripen in early August but do not fall from the tree immediately. The cherries are usually processed into jam, juice, or wine. The trees grow vigorously and are well foliated; they are winter-hardy and resistant to many diseases. Fruit production first occurs in the seventh or eighth year. The annual fruit yield from one tree is 6–11 kg. The Shubinka variety is grown in the central zone of the RSFSR.
