The Cadillac appellation was created in 1972. Grapes are required to be harvested entirely by hand and sales are limited to bottled wine. Approximately 80% of the grapes are *bottled, and the wine is fermented either in tanks or barrels. It is then matured in barrels in Lamothe's underground cellars. *Botrytis cinerea is a fungus that concentrates the sugar in the grapes. This 'noble rot' is important for all great, naturally sweet white wines.
