A single grapevine at Château d’Yquem in the Sauternes region of Bordeaux yields, on average, one 750 ml bottle of wine a year.
Answer: False.
The production of Château d’Yquem is famously one glass of wine per grapevine. The volume of liquid is tiny compared to higher yield vineyards around the world, which can average anywhere from two to ten 750 ml bottles of wine per vine. Many factors affect yield, such as grape variety, climate, vineyard location, and the condition of the grapes when they are picked. Château d’Yquem, for example, is made from shriveled grapes affected by the “noble rot” of Botrytis cinerea.
