There are many different types of grapes grown in Bordeaux and used in their famous wines.

In the past, there were just six varietals allowed for making red wine in Bordeaux: Cabernet Sauvignon, Merlot, Cabernet Franc, Petit Verdot, Malbec, and Carménre. White wines were limited to the use of Sauvignon Blanc, Sémillon, Muscadelle, Sauvignon Gris, Colombard, Ugni Blanc, Merlot Blanc, Mauzac, and Ondenc.

But in January of 2021, the governing body in Bordeaux allowed four new red varieties, including Touriga Nacional, Marselan, Castets, and Arinarnoa, as well as two white varieties, Alvarinho and Liliorila. This was done to give more viticultural options to grape growers to address climate change and combat less hospitable conditions. The new grapes will be listed officially as "new varieties of interest for adapting to climate change". This puts them third in the hierarchy behind "major" and "additional" grapes in official documents. This status will again be reviewed in 2031.

Under current restrictions, usage of the new varieties is limited. They may only account for five percent of the planted vineyard area, and a maximum of ten percent of a wine blend. Because of France's wine labeling regulations, these new varieties will not appear on Bordeaux labels. So, these changes to battle climate change will go relatively unnoticed for now.

Although you may not notice any real change in Bordeaux wine blends, they are changing as the world’s climate is changing. Cheers!
