Lees

the coarser parts of a liquor, its sediment or dregs. "Wine on the lees" means a generous, full-bodied liquor. (Isaiah 25:6) Before the wine was consumed, it was necessary to strain off the lees; such wine was then termed "well refined." (Isaiah 25:6) To drink the lees, or "dregs," was an expression for the endurance of extreme punishment. (Psalms 75:8)
