‘Global warming appears to have lurched Bordeaux forward into a changed state’

If you love the red wines of Bordeaux, this is a great time to be alive. There’s no historical parallel – in 2,000 years, so far as we know – for its recent run of good to great vintages. This profoundly maritime region fronting the capricious Bay of Biscay rarely managed to stump up more than three outstanding vintages per decade in the past, yet of the eight vintages between 2015 and 2022, only 2017 and 2021 fall short of excellence (and 2017 Pomerol and Sauternes are delicious).

The 2023 vintage is being assessed at present; still more surprising success seems possible. Those caring for vineyards will always face challenges, but global warming appears to have lurched Bordeaux forward into a changed state. Its most noteworthy feature? Reliably hot summers.

According to local Météo-France annual reports, June, July and August in 2015, 2016, 2018, 2019, 2020, 2022 and now 2023 have all been hotter than the moving 30-year summer averages. Only modestly so for 2016, but flamboyantly so for 2018 and 2022. Most of the seasonal challenges have tended to come in the first half of the year – notably downy-mildew pressure from the very wet spring weather of 2016, 2018, 2020 and 2023.

That pattern of wet early months, though, set the vineyards up to cope with summer heat admirably – and when spring rain didn’t show, timely summer storms saw the vines through. Drought cursed none of these vintages, though it threatened in 2022.

Among Bordeaux’s top châteaux, huge changes have been instituted in both vineyards and cellars. The use of cover crops and heat-adapted canopies have changed the short-term look of vineyards; new rootstocks and row orientations, a switch to massal selections (propagating from an estate’s best-quality existing vine stock) for replanting, and experiments with agro-forestry mark a slower but no less significant shift.

Harvesting is swift and targeted; fruit sorting futuristically finicky; gravity systems render pumps redundant; extraction is gossamer; there’s less new oak being used and more alternative storage vessels. The fine anatomisation of vineyards and the switch to small-lot vinification provides super-granular blending possibilities: the biggest change of all.

Is there a ‘but’? Well, the taste of ambitious Bordeaux has significantly changed over the last decade. The sunny, easygoing opulence which linked 1982, 1989, 1990, 2000 and 2009 is now in abeyance. There’s a new severity and cut to ambitious young Bordeaux, linked to the acidity, freshness and ‘precision’ sought by cellarmasters and lauded by wine critics. Anatomise these wines, though, and you can hardly fail to be impressed by their concentration, their layered intrica
