Burgundy truffle (lat. Tuber aestivum var uncinatum) is the autumn variety of black summer truffle. These truffles are available in the fall (September to late December) and look like small rocks with a rough surface. The exterior is brown, with large diamond-shaped points.
The interior is coffee-colored and veined. The aroma is musky, and the flavor is earthy and nutty, stronger than the summer truffle (because these truffles have spent more time underground), but not as pungent as the winter truffle. The price is much lower than that of black summer truffles.
