Are Wine Glasses Heat Resistant? (Explained)

There are heat-resistant wine glasses out there that you can buy if you fancy mulled wines, hot ciders, or other hot drinks.

However, it is very important to know which kind of glass you have. The heat can cause the glass to shatter, which could be dangerous.

If you want to drink something warm, it’s best to use a mug or another type of glass specifically designed for hot drinks.

Here’s How Heat-Resistant Wine Glasses Are:

Tempered glass wine glasses can withstand temperatures of up to 470 degrees F. Ensure the wine glasses you are using are specifically labeled as “heat-resistant.” Heat-resistant brands for wine glasses are Schott, JoyJolt, Vivocci, Bravario, Godinger, Libbey, Crate & Barrel, and Rastal.

Anatomy of a Wine Glass:

A wine glass has four components: 

  • Base
  • Stem
  • Bowl
  • Rim

The base of a wine glass is what keeps it stable. 

The stem elongates the glass without raising the wine’s temperature. It also prevents fingerprints from reaching the bowl of the glass.

The bowl is the glass’s most crucial feature. It should be big enough to allow for easy swirling of the wine without splashing it while also tapering down to retain and concentrate its aroma.

The rim lies in the uppermost part of the bowl. A smooth rim will not hinder the wine as it flows from the glass. A thick, rounded rim indicates low-quality glass.

Can You Put Hot Tea and Drinks in Wine Glasses?

Technically, no – you should not put any hot beverages in regular wine glasses.

The heat can cause the glass to shatter, which could be dangerous. If you want to drink something warm, it’s best to use a mug or another type of glass specifically designed for hot drinks.

If you have wine glasses made with heat-resistant materials, they should endure heat to a certain point.

Here are the types of wine glasses that are heat resistant.

Tempered Wine Glass: 

This withstands more heat and pressure than regular glass, so it’s safer for use with hot drinks. 

It can resist constant temperatures of up to 470 degrees F. Ensure that the tempered glass wine glasses you are using are specifically labeled as “heat resistant.”

Borosilicate Wine Glass: 

This type of glass has boron trioxide, which gives it a low degree of thermal expansion.

Compared to regular glass, it doesn’t shatter when subjected to high-temperature changes. 

This material can tolerate a working temperature of 515 °F and doesn’t melt until 550 °F. It’s become the premium glass of choice for high-end restaurants, laboratories, and wineries because of its durability.

Tritan Crystal Wine Glass: 

Tritan® crystal glass is a cutting-edge material developed by Schott Zwiesel. It has a high-temperature manufacturing process that includes tempering. 

This product features the best dishwasher resistance ratings.

Tritan crystal remains unmarked with no cloudiness, scratching, or loss of brilliance after an astonishing 3,000 domestic dishwasher cycles.

Can Wine Glasses Go In an Oven?

Wine glasses are not meant to withstand high heat levels, and they could easily shatter if placed in an oven. 

It’s best to avoid this scenario altogether and find another way to cook your food.

Some mugs and glasses can resist the heat of an oven, but most cannot. 

Unless they are designed for this purpose, such as Pyrex, drinking glasses, including wine glasses, are likely to shatter when the temperature changes.

How Much Heat Can Regular Wine Glasses Withstand?

Most regular wine glasses are not meant to handle over 200 degrees F (93 degrees Celsius). 

Thermal breaks occur when the glass expands and contracts due to temperature differences. So if you’re ever unsure, it’s best to err on the side of caution.

Are Stemless Wine Glasses More Heat Resistant?

There is no easy answer to this question, as it relies on the type of glass.

However, stemless wine glasses are more heat-resistant than regular wine glasses to handle somewhat higher temperatures.

Stemless wine glasses reduce the stress associated with holding a traditional wine glass. They are often referred to as “modern glassware.”

Onboard an aircraft, stemless glasses are frequently used to serve quicker and safer wine.

How Do You Know if Wine Glasses Are Heat Resistant?

The best way to know if your wine glasses are heat resistant is to check the material. 

There are many types of glass, and some are more heat-resistant than others (e.g., glass wine glasses). Find out what kind of glass your wine glasses are made of by doing a quick online search.

There are 2 types of wine glasses based on their composition.

Crystal Wine Glasses:

They enhance the aromas in wine while also adding a beautiful design, making them ideal for high-end dinners and formal events.

Because they eliminate the thicker lip edge, they may be spun into a very thin rim that produces a smoother drink flow against the tongue.

Crystal wine glasses are more expensive and can easily break.

Glass Wine Glasses:

They are more durable and less likely to break, making them better for restaurants and bars. 

They are non-porous, less expensive, and usually dishwasher safe.

What Makes a Glass Heat-Resistant?

Heat-resistant glass is designed to resist thermal shock. The silica-based compound is a heat-resistant material with a very low expansion coefficient and a high melting point. 

This form is most often used in the kitchen and industrial settings. It can endure temperature swings of up to 1000 ℃ (1,832 ℉). 

However, the typical glass would easily shatter if exposed to tremendous extreme heat.

Can You Put Wine Glasses in the Dishwasher?

You can only put wine glasses in the dishwasher if it’s marked to be dishwasher safe.

It’s important to note that low-quality wine glasses may not sustain high temperatures, and the machine may get as hot as 170 ℉. 

High-quality wine glasses are usually made with heat-resistant materials, and they can defy high temperatures with no issues. If you have a set of delicate wine glasses you don’t want to ruin, it’s best to stick them in the top rack of your dishwasher, so they don’t get banged around.

It’s better not to put any glass in the dishwasher because it can easily shatter and cause a mess if not handled properly. 

To clean your wine glasses, try using soap and water (and a good old-fashioned scrubbing if needed).
