When should I drink classed-growth Bordeaux?
A classed-growth claret is built on Cabernet tannin and new oak, and few reds repay long cellaring as reliably.
Windows are broad guides for well-made, well-stored examples of each style — producer, vintage quality and storage all shift them.
Why it needs time
The classed growths of the Médoc, Graves and Saint-Émilion, and their peers in Pomerol, pick ripe, thick-skinned fruit from low-yielding vineyards and age it for around eighteen months in a high proportion of new French oak. The result is dense tannin, firm acidity and a wood frame that all need time to integrate, which is why the window runs from eight to thirty years after the vintage. Left Bank wines dominated by Cabernet Sauvignon usually sit later in that range than Merlot-led Right Bank wines, and a first growth from a strong vintage can outlast even the closing figure.
Opened too early
Young top Bordeaux is mostly cassis, cedar and vanilla from the barrel, with tannin that coats the teeth and a finish that tightens rather than lingers. Many go through a closed phase somewhere between their fifth and tenth year, when the fruit retreats and the wine seems mute and severe. Opening one then is the commonest way to be disappointed by an expensive bottle.
In the window
As the oak melts into the wine, the fruit moves from fresh blackcurrant towards dried plum, and the bouquet fills with cigar box, graphite, pencil shavings, tobacco and forest floor. The tannin is still present but polished, and the wine gains length rather than weight. Mature claret is a savoury, digestible red that shows best at the table, with lamb or game.
Which vintages are ready
On the calculator’s figures, the classed-growth Bordeaux vintages in their window in 2026 run from 1996 to 2018, and those from 2004 to 2010 sit around the likely peak. Anything from 2019 onwards is still ageing. Enter your own vintage above to check it.

Frequently asked questions
How long should I age classed-growth Bordeaux?
Most need at least eight to ten years from the vintage before the tannin and oak settle, and many are at their peak somewhere between fifteen and twenty-five. First growths and the leading Pauillac and Saint-Julien estates in strong vintages can keep improving for longer. Merlot-led Pomerol and Saint-Émilion are often approachable a few years earlier than Cabernet-led Médoc wines from the same year.
Should I decant old Bordeaux?
Yes, mainly for the sediment. Mature claret throws a fine deposit, so stand the bottle upright for a day and decant it slowly shortly before serving. Younger classed growths benefit from two hours or more of air to loosen the tannin. Very old bottles can be fragile, so decant them at the last moment and taste promptly, as their aromas can fade within an hour.
