I'm making wine now, for the first time. After fermentation, it is necessary to "rack" the wine a few times. Racking is the process of gently siphoning the wine from the center of the large bottle or cask in order to dismiss the sediment that sinks, and the bits that float. If a wine were bottled fairly soon after fermentation, and racked only once, then you could expect some sediment to be in the bottle.
