History of the Kyoho Grape

Developed by a Japanese breeder Yasushi Oinoue in 1937, the Kyoho grape was created in Shizuoka, Japan, by crossing the Centennial grape and the Ishiharawase grapes. Oinoue was looking to develop a grape similar to the Concord grape with its large size and spectacular sweet flavor. Oinoue knew with a grape this amazing he had to give it a fitting name, and after visiting Mount Fuji, he decided on Kyoho. Kyoho translates to “great or big mountain peak.” Which is a perfect name for the great Kyoho grape that holds so much meaning to the Japanese culture.

It took several years for this grape variety to grow in popularity and become more commercially produced, but that happened in 1957. The Kyoho grape is now one of Asia’s most common grape varieties. Most of these grapes are grown in China and spread through other Asian countries and even in California, USA.

Cultural Significance

The grapes are continuously under surveillance during the ripening process by artful grape growers. They carefully place paper bags around each bunch to help ward off pests and diseases. Some of these grape bunches can cost 60 dollars. These growers expect nothing but perfection before selling these grapes to high-end fruit parlors across Japan.

Kyoho grapes are oblong and grow in clusters. Their skin is smooth, glossy, and thick and ranges from dark violet to black. The skin of these grapes is meant to be removed before consumption which is one significant aspect of these grapes. These grapes are a slip-skin variety meaning the skin can peel away from the flesh without causing damage. The meat of the grape is a translucent green and encases a few tiny seeds that should be discarded when eating.

They need about 6 hours of full sunlight and need to be planted in well-drained, slightly acidic soil. Watering should occur every day, but they are highly drought resistant once the plant is established.

Kyoho grapes are self-fertile and will start to bear fruit 2 to 3 years after being planted.

Harvesting season is around mid-august.

These grapes are known to handle cold winters and snowy climates and come back each year more impressive than the last.
