So that you don't get any sediment in your wine glass........

Explanation:

Typically, we would use decantation to separate a SOLID precipitate from a liquid; for instance a fine port from the crust that it throws on the bottom of the bottle. Of course we could do this in the chemistry lab as well, and achieve a preliminary separation of a liquid from a solid deposit.
