More grape varieties approved in Bordeaux

Four new red and two white wine grape varietals can be grown in Bordeaux as a result of formal approval by the Institut National de l’Origine et de la Qualite, a part of France’s Ministry of Agriculture.

The decision comes after years of research by scientists and growers who were focused on supplementing Bordeaux’s varieties to address the impact of climate change. Arinarnoa, castets, marselan and touriga nacional — a Portuguese varietal — are said to adapt well to stress from temperature increases.

The two new white varietals are alvarinho and liloria.

Bordeaux producers are loathe to change tradition, but the climate changes have forced their hand. With these grapes being first planted this year, it’s hard to predict who will use them and how they will change the flavor profile of these prestigious wines, but I can’t wait to try them.

Bordeaux may add grape varieties

Global warming has opened the door to additional grape varieties in Bordeaux. The General Assembly of Bordeaux AOCand Bordeaux Superieur has approved a new list of grape varieties that, if passed by the INAO, will help growers adapt to changing climate with hardier stock.

The present collection of six grape varieties will expanded by 7 more varieties. The reds included arinarnoa, castets, marselan and tourigna nacional and the whites include alvarinho, liliorila and petit manseng.

If approved, these secondary varieties cannot make up more than 5 percent of the vineyards or 10 percent of any blend. Furthermore, these grapes cannot be listed on the label.

It is not surprising that growers are seeing dramatic changes from the changing weather patterns. Grapes that flourished decades ago aren’t producing the same results as temperatures warm. Grapes are being picked later in the year and are loaded with sugar. The results are riper and more alcoholic wines.

I doubt we’ll see much change in the blends of first growths, but AOC and Bordeaux Superieur wines will quickly adapt these varieties. Yet, even they are planted next year, it will be several years before the new vines produce usable grapes.

Touriga nacional is a variety that does very well in Portugal. Alvarinho is another name for Spain’s popular albarino grape. Arinarnoa is a cross between tannat and cabernet sauvignon. Marselan is also a cross but between cabernet sauvignon and grenache. Petit manseng is grown in France along the Spanish border.
