To me, coffee and a mason jar are a perfect couple. In everyday life, mason jars have become a part and parcel. Although, I was literally worried about the heat tolerance of these jars. So, when it’s about hot coffee, I was pretty confused about the issue “Can I put hot coffee in a mason jar?”. Whatever, now it’s clear to me.
Yeah, you can put hot coffee into a mason jar! But, some facts you must know and follow. Here, I’m sharing all diggings and information I gathered about mason jars. Hope these will clear your so many questions that arise in your daily life. So, let’s start.

Mason Jars’ Heat Tolerance
Generally, mason jars go well at temperatures from 30° F to 220° F. But, it’s also seen that if the temperature swing does not happen, a mason is good in the freezer as well as in a temperature above 250° F.
Whether it’s high temperature or low temperature, the biggest enemy of the mason jar is temperature swing. So, when we place a room-temperature mason jar in the freezer, usually it won’t break. On the other hand, if we put an overheated jar in the freezer or vice versa, it will break.
Besides, as mason jars are heat-resistant, many people think that they can be used in the oven. The fact is that mason jars, no matter how heat-resistant they are, should never be used in the oven. Especially at temperatures above 1400° C, the jars start to melt.
So, whether it’s in the freezer or for keeping hot coffee, you can safely use them just by keeping in mind the temperature swings.
What is So Special About Mason jars?
Mason jars are basically glass jars that are made of annealed and borosilicate glass. They have metallic lids with bands. So, they’re so familiar as a versatile airtight jar. Food remains fresh for a long time rather than in other containers. When I think about containers, nothing is greater than a mason jar. Along with being multifunctional, it’s long-lasting, nontoxic, heat-resistant, non-reactive, affordable and so cute to look at.
From dry fruits to hot beverages, what you want, unimpededly you can put. We know that coffee is a highly acidic drink but in mason jars, there is no chance for harmful chemical reactions. Even you can make and drink your daily hot or cold coffee in these jars and keep the leftovers in the fridge for up to two days after cooling.
Thereafter, there are no odors and varieties of shapes of lids like plastic containers. Almost all the jars have similar lids which are quite relaxing for slovenly people like me. Moreover, cleaning and sterilization are also easy because of their wide neck. Overall, you have to love these jars as they are eco-friendly, hygienic, so glossy as well as cheap. It just gives your kitchen and dining table excellent hype.
Can Mason Jars Hold Hot Coffee?
Yes, mason jars can hold hot coffee. It’s common to see hot coffee being made in a mason jar. We know that it’s made of annealed glass. The glasses go through high temperatures and cool down slowly. This process reduces internal stresses and makes the glass tougher. After that, the glass is borosilicate glass. So, compared to other glasses, it’s capable of resisting thermal shock.
Although it’s recommended that before putting hot water or coffee or any extremely hot beverages, pour some warm water to avoid thermal shock. Especially, you must follow this tip during huge temperature changes (i.e- putting ice coffee and just then putting hot coffee). So, this process prevents your glass from breaking down.
Can I Put Hot Coffee in a Mason Jar in the Fridge?
Coincidently, when you’re too hurry to cool down your leftovers, you can put the hot mason jar in your fridge, although it’s not recommended at all. And when it’s about putting hot coffee in the fridge, it’s better to use a stainless steel container.
By any chance, if you don’t have them, you can simply use your mason jars as an alternative. This is non-reactive, non-toxic glass that keeps the prepared coffee fresh and rich with flavor in the fridge for a long time. Just be careful of rapid heat change.
Here are some tips to follow to keep the mason jars okay even in the fridge-
- Cool down your coffee properly. Put the jar on a rubber mat or towel while cooling down. When the coffee is cool enough, keep the jar sealing. Check the lid whether it’s sealed properly or not.
- If the jar remains still warm, Keep it away from other food as the temperature from the jar can spoil them, especially milk or milk-based food.
- If you already put rich-flavored foods in the fridge on any shelf, put the jar with coffee on another shelf or compartment. The flavor can still be absorbed even after being properly sealed.
- Don’t keep the jar close to the compressor. Things near the compressor cool down comparatively fast. So, there is a chance of thermal shock.
Some people prefer to put hot coffee in the fridge as they want to have a cold brew coffee instant without adding ice cubes. For that reason, it’s good to use an airtight stainless container and put them near the compressor (back side of the fridge). Enjoy your cold brew.
Why Do Mason Jars Crack in the Freezer?
Actually, mason jars are not made of tempered glass. So, air bubbles exist in the glass. These bubbles expand during extreme temperatures. This is why when we keep these jars in the freezer, those micro air bubbles expand and the glass breaks down or crack. Surprisingly, there may occur exploding while opening the lid.
Hopefully, you can avoid cracking and breaking by following some tips and they are-
- Keep empty at least 1” while putting in the freezer. The empty space must be increased when the jar is big. So, for big-size mason jars like 24 oz, keep up to 2” empty. In fact, after being frozen, foods or beverages expand and then the empty place work to give space.
- They have to be kept by their side in the freezer.
- Leave the jar with contents for cooling slowly at room temperature.
- Keep the jar in the fridge for one or two days to cool gradually.
- The lid should be a little loose while sealing the freezer and also thawing.
- Thaw the jar slowly. Never put it in the oven or hot water for quick thawing.
- Keep distance between freezer and jar or cooled containers and mason jars.
