Final answer:
The main grape varieties of Burgundy are Pinot Noir and Chardonnay, which are usually not blended but made into 100% varietal wines, with a few exceptions.
Step-by-step explanation:
The grape varieties of Burgundy are primarily two: the red Pinot Noir and the white Chardonnay. Burgundy is known for its focus on single grape varieties, meaning that most wines produced there are not blends, but are made from 100% Pinot Noir or 100% Chardonnay
There are exceptions, such as the appellation of Passetoutgrain which blends Pinot Noir and Gamay, and some Chardonnay wines may include a small percentage of another grape called Aligoté, but these are not the norm. For the most part, Burgundy wines are celebrated for being excellent expressions of their 100% varietal grapes.
