Wine Glassware Bases

Narrow Bases

Most heat transfer in a wine glass happens from the top down, unless the walls are super thin. Liquids arrange in layers, the top being the least dense and warmest, and the bottom being the most dense and coldest. If a wine glass is tall & narrow, only the small top surface warms up from surroundings, and the the bottom stays cold. One because the warmer top is a larger distance from the colder bottom, and two because each density layer has less surface area in contact with the warmer wine layer above it.

Since the wine warms up more slowly, its aroma releases more slowly.

Wide/Bulbous Bases

Most heat transfer in a wine glass happens from the top down, unless the walls are super thin. Liquids arrange in layers, the top being the least dense and warmest, and the bottom being the most dense and coldest. If a wine glass is widel & short, the beer warms up more quickly. One because the warmer top is closer to the colder bottom, and two because each density layer has more surface area in contact with the warmer wine layer above it.

Since the wine warms up faster, its aroma releases more quickly.

Stemmed Bases

Glassware with stems provide a wider bottom for glasses with narrow or round bases. A person can hold the stem and eliminating heat transfer from his/her hand. This may be appropriate for certain wine styles that should stay cold. Finally, stemmed glasses look elegant, which adds to the attractive appearance of poured wine.

Stemless Bases

This type of base creates a wide bottom to stabilize tall or narrow wine glasses. It flares out and is made of thick, solid glass to add weight. The added weight lowers the center of gravity and the flare gives it a wider tipping point. These are beneficial when pouring wine in and if it's bumped accidentally.
