Pineau d'Aunis (also known as Chenin noir) is a red French wine grape variety that is grown primarily in the Loire Valley around Anjou and Touraine.
A favorite of Henry Plantagenet, the English king had Pineau d'Aunis wine first brought to England in 1246. Today the grape is permitted in several Appellation d'origine contrôlée (AOC) wine regions of the Loire Valley, including Cheverny and Coteaux du Vendômois.
While a red wine grape, Pineau d'Aunis is often treated like Pinot noir and used to make rosé and white wines in both still and sparkling wine styles.
