Sediment is the grainy, non-liquid material that settles at the bottom of a bottle of wine. Sediment is traditionally found in older wines.

Although generally associated with finer red wines, sediment occasionally appears in some white wines, usually in the form of nearly colorless crystals. Over time the tannins and pigments in the wine start to break down which creates the sediment at the bottom of the bottle. Sediment can also mean that little or no filtration was used during the winemaking process, and for that reason sediment can also be found in new wine vintages as well as older wines.

To prevent sediment in your wine glass, there are some things you can do. You can stand the wine bottle upright rather than storing it on its side before serving the wine. Another thing you can do is to decant the wine, which means pouring it into a separate serving container before pouring it into your wine glass.
