The Moelleux cuvées are made in vintages when at least a portion of the vineyards produce grapes that carry significant levels of natural sugar. Botrytis sometimes occurs but it is not necessary in order to declare a Moelleux. Conditions of “passerillage”, that is extended exposure of the grapes to sun and high luminosity, create the impetus to release wines as Moelleux. Wines so declared can carry formidable leves of residual sugar: 25 grams is perhaps the minimum but more often the Moelleux at the Foreau domaine has 35 or 50 or sometimes even 80 or 90 grams of sugar left in the wine. The goal is to create a wine that is in perfect balance, maintaining a proper level of acidity while keeping the ultimate alcohol level under control.
