What is wine sediment?
Wine sediment is the solid substance that you sometimes see at the bottom of a wine bottle or glass. It is made up of different solid particles involved in the wine making process called dregs. The sediment is evidence of an aged wine and usually means that the wine has not been filtered. This does not in any way mean that the wine is bad or has gone off: in fact, wine that has sediment in the bottle is often quite good.
