Among its rolling hills and centuries-old vineyards, Katsunuma in Yamanashi Prefecture stands out as the crown jewel of Japanese viticulture.
As the world rediscovers Japan’s winemaking prowess, there’s no better time to explore the incredible flavors of wines crafted with precision, heritage, and passion. This article takes you on a flavorful journey through the famed Koshu grape and why the Japanese wine experience here is like no other.
Introduction to Japanese Wine
Why Japanese Wine Is Gaining Global Attention
Japanese wine is rapidly gaining global recognition, thanks to its nuanced flavor profiles, meticulous production methods, and ability to pair harmoniously with a variety of cuisines. Unlike the mass-produced wines of larger regions, Japanese wines are crafted with artisanal care—most notably in Yamanashi’s Koshu Valley.
The Signature Grape: Koshu of Yamanashi
A Brief History of Koshu Grape
The Koshu grape, native to Japan for over 1,000 years, is a vinifera variety believed to have traveled from the Caucasus region via the Silk Road. Today, it is the pride of Yamanashi Prefecture and the foundation of Japan’s most distinctive white wines.
Unique Flavor Profile of Koshu Wines
Koshu wines are revered for their pale color, crisp acidity, and light, floral aromas. Expect hints of citrus, white peach, and mineral undertones. Its low alcohol and subtle character make it ideal for delicate Japanese dishes.
Traditional vs. Modern Winemaking Techniques
Koshu wine is crafted in three primary styles:
- Sur Lie: Light and vibrant with a clean finish.
- Oak-Aged: Richer with vanilla and nutty notes.
- Unique Expressions: Winemakers experiment with fermentation and blending to create complex wines with a distinct Japanese identity.
