Birth-year Bordeaux: which wines last 21 years?
The year is fixed the day the child is born. The tier, the format, and the cellar are the parts left to choose.
The short answer
A red
The Médoc crus and Sauternes reach 21
The CIVB (opens in a new tab) gives its keeping figures by appellation. Set against an 18th or 21st birthday, the ones that clearly get there are the
The ranges are broad because every appellation holds estates of every ambition. At the top they stop meaning much.
The year is already chosen
The year is the one thing not open to choice, and its vintage report is worth reading before the wine is chosen. A year that favored the Right Bank points one way, a year that favored the northern
A 21st birthday falls 21 years after the vintage, an 18th after 18; the vintage guide says what each year gave. A child born in 2005, for example, shares a birth year with one of the 3 vintages the trade calls great, with 2009 and 2010, strong on both banks. A child born in 2008 shares it with a year when April frost hit the Merlot (opens in a new tab) and a cool August followed; the Right Bank came out ahead of the Left, and the dry whites were good.
For a child born around harvest time, the wine of its birth year does not exist in bottle yet. It is tasted from barrel the following spring and sold en primeur before it is bottled, and the bottles reach the buyer 1 to 3 years after that. The 2026 harvest began in August, weeks earlier than usual, after a hot, dry summer.
A magnum ages more slowly
Larger bottles age more slowly. A magnum holds 2 times the wine of a standard bottle under about the same pocket of air, so each glass of it meets less oxygen over the years, and the effect grows with time. That is the argument for a magnum when the opening is 18 or 21 years away.
The large Bordeaux formats are the magnum (1.5 liters), the double magnum (3 liters), the Bordeaux jeroboam (4.5 to 5 liters), and the imperial (6 liters). At
The cellar is chosen every day
A bottle kept for 2 decades needs a steady 10 to 13 °C (50 to 55 °F), 70 to 75% humidity, good ventilation, and no light. The tier and the format are chosen once. The cellar is chosen every day for 18 years.
