How can a wine be identified as 'sur lie'?

A wine identified as 'sur lie' means that it has been aged on its lees, which are the dead yeast cells and sediments that remain after fermentation. This aging process can enhance the wine's complexity, texture, and mouthfeel, often imparting additional flavors and a richer profile. The interaction between the wine and the lees during this period can also introduce a creamy, nutty character, which is particularly desirable in certain wine styles, such as some white wines, sparkling wines, and even some wines made from specific varietals.

Aging 'sur lie' is a traditional technique used in many wine regions, especially in France, where it is commonly practiced for wines like Muscadet and certain styles of Champagne. This method is particularly valued as it contributes to the wine's overall balance and can influence the aroma, making for a more enjoyable tasting experience. The other options describe characteristics that do not specifically relate to the term 'sur lie.'
