The Wine Project


How to draw the best out of the terroir ! Since 2015, Grotte Saint Marcel has become a natural cellar where wine is aged. Uniform temperatures and humidity, total darkness, its carbon dioxide level … the ideal conditions for exceptional wines !

Saint Marcel’s winegrowers initiated the project and have taken to ageing their best vintages in Grotte Saint Marcel for around 2 years, notably their Côtes du Rhône Villages Saint Andéol. Comparative tasting sessions of the same vintages raised above ground on their estate and down in the cave leave no doubt: the wines matured underground gain in subtlety, freshness and minerality and their spicy and fruity flavours are more intense.
