Diesel

DIESEL (see also PETROL below).
Aroma constituent reminiscent of diesel/petrol/gasoline engine fumes. Occasionally detected in botrytis affected sweet or semi-dry wines such as Riesling. Considered a flaw if too obtrusive.

A diesel aroma in wine, surprisingly, is considered to be a positive attribute, but it can be excessive in wines made with the Niagara grape.

An odd and strangely appealing character in older, well-cellared Rieslings, particularly those from Germany's Rhine and Mosel. See also "diesel" and "mineral."
