🧐 FAQs: Best Japanese Wine & Visiting Yamanashi
Q1: What makes Koshu the best Japanese wine?
Its heritage, elegance, and food-friendliness make it a standout. Koshu wines are light-bodied, low in alcohol, and feature delicate flavors like citrus, white peach, yuzu, and minerality. This makes them exceptionally food-friendly, especially with Japanese cuisine. Koshu’s clean acidity and soft palate pair beautifully with dishes like sashimi, tempura, yakitori, and grilled fish, enhancing rather than overpowering subtle flavors.
Q2: Is red wine popular in Japan too?
Yes—Japan’s red wine scene is blossoming alongside its iconic white wines. The most widely planted red grape is Muscat Bailey A, known for its fruity profile, soft tannins, and slightly sweet finish. Other popular varietals include Merlot and Cabernet Sauvignon, which thrive in the cooler climates of Nagano and Yamanashi, while Black Queen and Kai Noir represent uniquely Japanese hybrids developed to suit the local terroir. As Japanese tastes shift and more Western cuisine is enjoyed, demand for red wine is steadily increasing. Today’s winemakers are embracing techniques like barrel aging, natural fermentation, and European-inspired blending to meet evolving preferences. These red wines pair beautifully with miso-based dishes, yakiniku, tonkatsu, and soy-glazed vegetables, with Muscat Bailey A particularly suited to teriyaki and sukiyaki. While Koshu remains the white wine hallmark of Japan, red varietals are gaining recognition—offering richness, diversity, and exciting new directions for Japanese winemaking.
