Château Mercian

Japanese Koshu and Bordeaux blends from Yamanashi-ken's premier producer.

Château Mercian produces wines in Yamanashi-ken, Japan's premier wine region. The winery focuses on Koshu, the indigenous white grape that defines Japanese viticulture, alongside Bordeaux varieties grown in local vineyards. The Koshu, a mineral and delicate expression of the varietal, and the Iwasaki Koshu demonstrate the winery's commitment to the grape's potential. The Mariko Vineyard Omnis, a blend of Merlot, Cabernet Sauvignon, and Cabernet Franc, reflects the region's capacity for structured red wines. Wine Spectator and Decanter have rated these wines, recognizing their quality across both indigenous and international varietals.
