Pot Ale And Spent Lees - Whisky Magazine

The quantity of spent lees remaining in the pot still accounts for around one-third of the charge. This is significantly lower (proportionately) than pot ale, due to the low wines containing a lower level of water than the wash. At Glenmorangie for example, a charge of 7,500 litres results in 2,500 litres of spent lees.
