Grape Republic was established in 2017 in Yamagata prefecture, northeast Japan. 100% made from grape which were ripened in Nanyo City and add nothing else. A land suitable for making grapes, where it has a climate with an intense temperature gap, low humidity throughout the day and a smooth drain geology, but cultivation abandoned areas are noticeable here and there now.

The winery reclaims abandoned vineyards, among to inspire a return to the land with terroir-driven wines. Featuring Spanish amphorae, the winery favors micro-oxygenation for clean, complex wines, persisting in their commitment to organic practices without added SO2. Their main grape variety, Delaware, with pink skins, yields both white and amber wines.
