Kikuka Town, Yamaga City, where our grapes are grown, is located at the northern edge of Kumamoto Prefecture. The town borders Fukuoka and Oita Prefectures and lies in a mountainous region surrounded by peaks such as Mt. Happo, Mt. Mikuni, and Mt. Kunimi, all rising to approximately 1,000 meters above sea level. The vineyards cultivated under contract by members of the Kikuka Town Grape Production Promotion Association cover a total of approximately 7.5 hectares and are scattered across about 30 locations throughout the town. Their elevation ranges from 100 to 200 meters. The region is blessed with more than 2,000 hours of sunshine annually. During the grape growing and ripening season (from May to September), sunshine totals approximately 1,100 hours, making the area a highly favorable environment for viticulture. On the other hand, rainfall exceeds 1,700–2,000 mm annually. To protect the grapes from diseases, all vineyards are equipped with rain shelters. An additional benefit of these shelters is that they reduce the frequency of pesticide applications, enabling lower-chemical cultivation. Yamaga City also has around 80 natural springs. In Kikuka Town, where the vineyards are located, the water temperature is approximately 14°C, compared with 16–19°C in other regions. This water helps cool the soil and is thought to contribute to the diurnal temperature variation. It is no surprise, then, that Kikuka Town produces high‑quality grapes. The soils of Kikuka Town consist of light-colored Andosols (volcanic ash soils), brown lowland soils, brown forest soils, lowland paddy soils, and gray lowland soils, and vineyard parcels are selected accordingly. In vineyard management, we enhance vine growth through proper pruning and manage fruit health and development by performing early leaf thinning from the flowering stage onward. This canopy management, combined with the local climate (microclimate) and soil characteristics, contributes to the formation of the Kikuka terroir. Grapes grown with the utmost care are harvested entirely by hand, with each cluster carefully sorted during picking. Our ultimate goal is to harvest “healthy fruit” to produce wholesome wine.
