Mongaku Valley Winery
モンガク谷ワイナリー
Pioneering field blends in Hokkaido's cool-climate terroir
Located in the Nobori district of Yoichi, Hokkaido, Mongaku Valley Winery was established in 2012 by Shigeki Kihara, who relocated from Tokyo. The winery is renowned for its unique approach to viticulture and winemaking, specifically the practice of field blends (co-planting and co-fermentation). By cultivating various grape varieties together in the same vineyard, Kihara aims to express the complex terroir of the Mongaku Valley. The wines are characterized by their natural elegance, vibrant acidity, and a distinct sense of place, reflecting the cool climate of Hokkaido. The winery emphasizes sustainable practices and minimal intervention to ensure the purity of the fruit is preserved in every bottle.

楢
Nara
WhitePinotage · Pinot Noir · Pinot Gris · Sauvignon Blanc · Chardonnay
The most distinctive of the trio. Pinotage-dominant (54% in 2024), Nara expresses the unique, spicy character of this rare variety in a blanc de noir style. Floral and honeyed on the nose with lychee, grapefruit pith bitterness, and saline minerality. Pinotage's characteristic spice and structure give Nara a bold, unconventional profile that stands apart from most Japanese whites.
栢
Haku
WhiteChardonnay · Pinot Noir · Pinot Gris · Pinotage · Sauvignon Blanc
Haku is the lightest and most aromatic of the three main cuvées. Chardonnay-dominant (61% in 2024), it features a bright, Champagne-like complexity with ripe citrus, white flowers, and a clean mineral finish. The subtle influence of Pinot Noir and Pinotage adds delicate structure without weight. Haku is designed for immediate pleasure but also rewards 1–2 years of aging.
栃
Tochi
WhitePinot Noir · Pinotage · Pinot Gris · Chardonnay · Sauvignon Blanc
Mongaku Valley's flagship cuvée. A Pinot Noir-dominant field blend of 5–7 co-planted varieties, wild-yeast fermented and bottled unfined and unfiltered. The 2024 vintage comprises Pinot Noir (64%), Pinotage (23%), Pinot Gris (5%), Chardonnay (4%), and Sauvignon Blanc (4%). Despite being a white wine, the dominant Pinot Noir gives Tochi a firm, three-dimensional structure that sets it apart from most whites. The palate shows dashi-like umami, saline minerality, and a complex, long finish.
桧
Hinoki
WhitePinot Noir · Pinotage · Pinot Gris · Sauvignon Blanc · Chardonnay
The experimental series of the Mongaku Valley lineup. While the three main cuvées (Tochi, Haku, Nara) follow a consistent field blend philosophy, Hinoki explores different winemaking approaches with each vintage — including extended maceration, unusual assemblages, and limited production runs. Some vintages are released as white wine; others as red. Named after Japanese cypress, the only needle-leaf tree among the acorn-named cuvées, reflecting its unconventional character.
