a persimmon variety that is astringent when raw
A type of persimmon that tastes harshly astringent when eaten fresh. It becomes sweet only after the astringency is removed by drying or other treatment.
Composed of 渋 (astringent) + 柿 (persimmon). The astringency comes from tannins; it is removed (渋抜き) by drying, or by treating with alcohol or warm water, which turns the fruit sweet.
