Wine regions

The regions on this map have a collectible tier in common and little else. Bordeaux is the largest fine-wine economy: about 110,000 hectares of vines, of which a few hundred classified châteaux release thousands of cases each through the en primeur system, so its prices are the most transparent and its wines the most traded at auction. Burgundy is the opposite case — about 33 grands crus on roughly 550 hectares, holdings measured in rows rather than hectares and production of a few hundred cases per wine — so scarcity, not scores, sets the price.

Champagne is a brand economy: some 16,000 growers sell grapes to about 370 houses, and the prestige cuvées carry the margin. The Rhône, Piedmont and Tuscany each pair a large everyday region with a small delimited core — Hermitage and Côte-Rôtie, Barolo and Barbaresco, Bolgheri and Montalcino — whose top wines trade internationally while the wider region sells at everyday prices. Rioja and the Mosel are the value tiers of the collectible world: long-aged gran reservas and sweet Prädikat wines with decades of auction record at a fraction of the Bordeaux price.

In the United States, Napa Valley shows what land does to a bottle: about 45,000 acres, under 4% of California’s vineyard, with land values reported in the hundreds of thousands of dollars per acre feeding cult wines sold by mailing list. Oregon’s Willamette Valley and the sparkling districts of Carneros and Anderson Valley apply Burgundian and Champenois methods on land that costs a fraction as much.
