Packaging Materials: Bottles, Glass, and Closures

Packaging is not just a container. It is a signal. Before a buyer tastes anything, the bottle in their hand tells them whether your wine is premium or cheap, traditional or modern, worth $15 or worth $40. At commercial volume those choices also drive real cost, so make them deliberately.

Bottle Shapes

Wine bottles fall into two main shapes, both originally from France:

• Bordeaux bottles, also called claret bottles, have distinct high shoulders that drop into a straight profile. Used for Cabernet Sauvignon, Merlot, Zinfandel, and Pinot Grigio.
• Burgundy bottles have gently sloped shoulders that run smoothly down the body. Used for Pinot Noir, Syrah, and Chardonnay.

Match the shape to your varietal. It is what buyers expect, and breaking the convention without reason just looks like a mistake.

Bottle Color

Color is functional as well as aesthetic:

• Antique green, dead leaf green, and classic green protect red wines from light exposure.
• Flint, meaning clear glass, shows off the color of whites and roses.
• Heavier bottles signal quality and are typically used for premium wines. If you are positioning above $20, the weight of the glass is part of the message.

Closures: Cork Versus Screw Cap

The closure carries both function and perception:

• Cork is associated with tradition and premium wine. It seals naturally but carries a risk of cork taint, caused by a compound called TCA, short for 2,4,6-trichloroanisole, which can spoil the wine.
• Screw caps are often wrongly seen as cheap, but they preserve wine quality well, eliminate cork taint, and open without a corkscrew.

Choose based on your positioning and your tolerance for cork taint risk. Many serious commercial brands now use screw caps without any loss of prestige.
