Chateau Mercian — Yamanashi Koshu 2023
Koshu, Yamanashi, Japan 🇯🇵

Overview
Crafted from 100% Koshu, Japan’s indigenous grape variety cultivated for centuries in Yamanashi Prefecture, this wine beautifully showcases the elegance and precision that have become the hallmark of Chateau Mercian. Delicate, mineral-driven, and refreshingly distinctive, it offers a unique expression found nowhere else in the wine world.

Aromas & Flavors
Japanese citrus, green apple, white peach, subtle lychee, delicate tropical fruit, white flowers, and a gentle saline minerality unfold with remarkable finesse and purity.

Mouthfeel
Light- to medium-bodied with vibrant acidity and a silky, refreshing texture. Bright and beautifully balanced, the palate delivers subtle weight without heaviness, finishing long, clean, and mineral-driven.

Food Pairings
Sushi, sashimi, shrimp, oysters, grilled white fish, fresh salads, tempura, or lightly seasoned seafood dishes.

Verdict
A captivating white that combines elegance, precision, and originality. Refreshing yet thoughtfully complex, it offers a distinctive personality that continues to elevate Japan’s growing reputation as a serious fine wine producer.

Koshu is Japan’s signature indigenous grape, with a history dating back more than 1,000 years in Yamanashi Prefecture. Its naturally delicate aromatics and vibrant acidity make it one of the world’s most versatile partners for Japanese cuisine.

🍷 Personal Pick
Japanese wines have evolved tremendously over the past two decades, and Chateau Mercian continues to lead that transformation.

It’s educational, unexpectedly delicious, and a beautiful reminder that some of the world’s most memorable wines come from places many enthusiasts have yet to explore.
