Siro is a white wine from Sennoyume Winery (Ishinomaki, Miyagi) made from Delaware, Chardonnay, and Steuben grapes grown in Kaminoyama, Yamagata. The winemaker describes the 2024 vintage as an assemblage of Steuben's Blanc Noir clone, early-picked Chardonnay, and Delaware -- with a small addition of a Seibel-family hybrid grape for texture -- fermented separately to draw out each variety's character before blending toward a light, clean style inspired by Japanese sake's 'tanrei karakuchi' (dry and crisp) profile. It pours a clear, pale lemon-yellow and opens with green apple and citrus (lemon, grapefruit) aromas layered with white flower and herbal notes, plus a faint sake-like ginjo-ka aromatic lift and Delaware's characteristic gentle sweetness in the background. The palate is bright and refreshing, with Steuben's Blanc Noir lending light body and early-harvest Chardonnay contributing freshness, a subtle mineral edge on the finish, and a short, clean aftertaste with faint citrus bitterness. Made with no added sulfites and bottled unfiltered.
Siro channels the crisp, dry restraint of Japanese sake into a wine glass -- a study in clarity from a winery whose other cuvées lean toward richer texture.
New to wine?

Terroir & Winemaking
2024 vintage: Delaware, Chardonnay, and Steuben grown in Kaminoyama, Yamagata Prefecture, Alc. 11.0%. The winemaker's own notes describe the blend as Steuben's Blanc Noir clone, early-picked Chardonnay, and Delaware, with a small addition of a Seibel-family hybrid grape for added texture and mineral character on the finish -- though the formal varietal listing cites only Delaware, Chardonnay, and Steuben. Each component is fermented separately (no added sugar, acid, or sulfites) before assemblage, and the wine is bottled unfiltered. As with several other Sennoyume Kacho-Fugetsu-adjacent cuvées (e.g. Hana, Sora, Kaze), exact blend proportions and even grape composition can shift from vintage to vintage, so it is worth checking the current release's label for specifics.
