But where do these stellar fruits hail from? It’s none other than the Land of the Rising Sun itself. Kyoho grapes were bred in Japan in the 1930s and quickly became a popular variety. The name “Kyoho” translates to “giant mountain grapes”, hinting at their large size and the mountainous regions they thrive in. The parent varieties that were crossbred to produce the Kyoho were Ishiharawase and Centennial, chosen for their excellent flavor and size traits, respectively.

Though the Kyoho was originally bred in Japan, it’s now grown in several countries worldwide, including China, Korea, and the United States, particularly in California. However, Japan remains the leading producer of Kyoho grapes. Specific regions in Japan, such as Yamanashi and Nagano, are particularly famed for their Kyoho grape cultivation. They offer the perfect combination of soil composition and climate, ideal for nurturing these juicy, sweet, and slightly sour grapes.


Popular Desserts Made from Kyoho Grapes

Kyoho grapes aren’t just enjoyed as a fresh fruit; they’ve also found their way into the kitchen, with chefs using them to create delectable desserts. The grape’s natural sweetness and slight tartness make it an ideal ingredient for a variety of sweet treats.

Farmers take great care during the harvest season to ensure the grapes are picked at just the right time. The grapes need to be ripe enough to reach their full flavor potential, but not overly so that they become mushy or spoil quickly. It’s a delicate balance that requires a good understanding of the grape’s growing habits and close monitoring of the vineyard.


When are they harvested?

In Japan, Kyoho grapes are typically harvested in late August to September. This is when the grapes have developed their characteristic large size and sweet, slightly tart flavor. However, the exact timing can vary based on the local climate and weather conditions. In regions with milder summers, the harvest might start a bit later, while in hotter regions, it could begin earlier.

Harvesting Kyoho grapes is a labour-intensive process, requiring careful handling to avoid damaging the fruit. The grapes are often hand-picked, one cluster at a time. After picking, the grapes are carefully packaged to protect them during transport.
