Bordeaux bottles (also less commonly called Claret bottles) contract sharply at the neck. This configuration makes them stay in a slanted wine rack a little better. Traditionally people use the green bottles for red wines and the clear (or "flint") bottles for white wines, although you may use them as you see fit!. This style of bottle is used for many commercial wines in France and elsewhere around the world. While tradition is a strong motivator, you may certainly use this bottle for any type of wine, at your pleasure. These bottles are 1.5 liters, or about a gallon and a half. They are cork finished, which simply means that they must be closed using a cork. They come 6 bottles to the case. Actual shipping rates apply to all cases of bottles.
