About

Grand Cru: The Wine Maker is a turn-based wine-making tycoon set in Bordeaux. Score your terroir, age vintages in oak, and balance the four pillars of quality — then out-negotiate 25 unique buyers with your own pricing strategy while volatile weather RNG threatens every harvest. From terroir scoring to Michelin-star contracts, every vintage is a high-stakes economic calculation where critics and the public pull in different directions.

From Grape to Glass, Every Choice Matters

In Grand Cru, every decision you make — from the vineyard to the wine glass — shapes your wine's final score.

🌍 Terroir — Soil type, climate, and vine age determine your grape's potential before you touch a single cluster.

🪵 Oak Barrels — French, Hungarian, or American oak — each variety, freshness level, and grape tolerance shifts the flavor profile. Pick wrong and you'll flatten the fruit.

⭐ Four Pillars of Quality — Your wine is scored on Structure, Authenticity, Finish, and Complexity — just like real wine critics evaluate Bordeaux.

📊 Critics vs. Public — Critics reward complexity and structure. The public wants fruit and approachability. The same wine can score 90 with one and 65 with the other. Know your market.

Create your own wine style. Your vineyard, your rules.
