Literally, wine not in a bottle. Wineries of all types, sizes, and levels of quality buy and sell wines in bulk. Some sell all of their production that way. Most large producers buy significant amounts of bulk wines from other wineries and then BLEND, bottle, and distribute those wines under their own labels. Small, prestigious wineries, however, may also sell small amounts of high quality wine in bulk to producers who will use it to enhance their own wines. In harvest years when the size of the crop is small, the prices for bulk wine go up.
