Château de la Roulerie Coteaux du Layon is a sweet white wine produced by Château de la Roulerie, located in the Loire Valley of France. Chenin Blanc grapes are harvested late in the season when they may be affected by botrytis, this further concentrates the sugar and acidity in the grapes. The must is partially fermented leaving a high level of residual sugar in the wine, after which they are matured in old, large oak barrels prior to bottling.
