There are three “basic” bottle shapes for wine with many variations in-between.
Bordeaux-style bottles have straight sides and tall shoulders.
Burgundy-style bottles have sloping shoulders and are a tad fatter than Bordeaux style. You will find many Chardonnay and Pinot Noir wines use this type bottle.
Alsace and Mosel bottles are thin and tall with sloping shoulders. Wines such as Riesling use this shape.
All of these shapes allow bottles to be stored horizontally, which keeps the cork moist and the seal good.
