Bailey and Golden Queen
Black Queen, crossed by Zenbei Kawakami in 1927, is the progeny of Bailey and Golden Queen. While it shares Bailey as a parent with Muscat Bailey A, the other parent is different. These are separate varieties developed in the same year.
Deep color and acidity
Iwanohara Vineyard presents wines with deeply colored, thick-skinned grapes and pronounced acidity. In Zenbei 2022, 23% is used in the blend, paired with Muscat Bailey A and others. Even knowing part of the blend, you cannot explain the entire wine’s taste based solely on this grape.
Additionally used as a parent variety for crossing
Kai Noir, bred in Yamanashi Prefecture, is a cross between Black Queen and Cabernet Sauvignon. Kai Noir is not another name for Black Queen. Organize parentage and blend relationships in products using different connections.
