Trousseau or
Trousseau Noir, also known as
Bastardo, is an old variety of red wine
grape originating in eastern
France. It is grown in small amounts in many parts of Western Europe; the largest plantations are today found in
Portugal, where most famously it is used in
port wine. It makes deep cherry red wines with high alcohol and high, sour candy acidity, and flavours of red berry fruits, often complemented - depending on production - by a jerky nose and an organic, mossy minerality.
