As winemakers across Spain and around the world scramble to cope, they’ve increasingly looked to the past, resurrecting late-ripening and heat-tolerant varieties they might have shunned decades earlier.
In California, vintners are embracing grapes such as mourtaou, a nearly extinct variety from south-western France, to create peppery reds, while some in France’s Cognac region are toppling more than a century of tradition to trial climate-resistant grapes. In Bordeaux, concerns about the climate crisis recently helped to secure the approval of six new grape varieties, including castets, a disease-resistant variety that had been on the brink of disappearing.
