Term (also coarse yeast) for the yeasts after fermentation that deliberately remain in contact with the wine for some time. If the young wine is racked, it is separated from the full yeast (sediment). Only the parts still in suspension remain in the wine and are then called fine yeast. Storage or ageing on the lees is described under lees storage. The dead yeasts are also referred to as lees.
The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
