About this ingredient
Premium Japanese hybrid grape (Kyoho cultivar developed 1937 in Shizuoka) — Yamanashi Prefecture is the leading commercial producer. Distinguished by exceptionally large fruit size (~14g per berry vs ~5g for Concord), intense sweetness (Brix 18-20), and a thick black-purple skin rich in anthocyanin. Used as a premium gift fruit, in juice for premium beverage retail, and increasingly as feedstock for resveratrol / anthocyanin functional ingredients. Distinct from existing yamabudo (wild Japanese grape) entry.
