Biltmore Estate Chardonnay Sur Lees

[wondersofwine]

I knew it meant that the juice was left on something but wasn't exactly sure what so found a wine dictionary on wine.com:

Indicates a wine was aged "on the lees" (sediment consisting mainly of dead yeast cells and small grape particles). This process is a normal procedure for fermenting red wines; Burgundian winemakers discovered that it often added complexity to their Chardonnays, and now this process enriches many white wines from around the world.

Note that the French word "lies" is translated to "lees" in English so your spelling was closer to the English. (and both words are pronounced the same with a long 'e' sound.
