- Sediment - The solid material which settles to the bottom of any wine container, whether it be a bottle, tank, cask or barrel.
This sediment is a very heterogeneous mixture which at the start of wine-making consists mainly of dead yeast cells. The insoluble fragments of grape pulp and skin, and the seeds that settle out of new wine.
Sediments in bottled wines are relatively rare, and usually signal a fine wine that has already spent some years in bottle. Many winemakers therefore take great pains to ensure, throught clarification, stabilization and filtration, that the great majority of wines made today will be drunk within their first few years, will remain free of sediment for at least few years.
