A big question I’ve been getting lately is, ” Are blender bottles microwave safe? ” The answer to this question varies across the internet and I am hoping to shed some light on the topic. First things first, it is important to always ensure your safety when putting items into the microwave that you’re not confident about. If you’re not sure, then it is probably the safest bet to avoid microwaving that item.
Personally, I have experience over the past year of needing to microwave my blender bottle or shaker cup. My profession is teaching and I often need large amounts of coffee to get me through the day. Unfortunately, I was lacking a travel coffee mug and instead used one of my shaker cups.
Blender Bottles And Heat
Over the course of an entire school year (September through the beginning of June) I filled my blender bottle with coffee and brought it to school. This process brought me both a positive and negative experience.
On the positive side, blender bottles are leak proof and can handle quite a bit of heat even though it is made of plastic. In addition to this, if you use a BPA free blender bottle or shaker cup, you will not have to worry about poisonous effects from the warming plastic. All in all, I happily used my bottle for coffee on a daily basis and suffered no major injuries or health side effects (Disclaimer: Personally I was not influenced but this is not to say it cannot influence you).
On the negative side, the cover to my blender bottle cracked and thus began to leak. This was most likely due to the high pressure build up within the bottle containing a hot liquid. That being said, it is always important to expect your bottle to spray a little liquid when opening the cap under the high pressure of a hot liquid.
All in all, I had no major issues and would likely use my blender bottle for coffee once again if needed.
Due to a blender bottle not being insulated, I did have to microwave my coffee on many occasions. When asking myself, “Are blender bottles microwave safe?” There are a few things to consider.
Things To Consider when Microwaving a Blender Bottle
At the end of the day, when questioning are blender bottles microwave safe, the choice is truly yours! Like I said, I had no major issues when using my blender bottle for coffee and in a microwave.

But, there are a few things to keep in mind.
First, you must absolutely make sure that you do not microwave your blender bottle with the metal ball inside! Metal is a natural conductor. This means that electricity flows through it quite easily. If you microwave metal, you will most likely destroy your microwave and see sparks fly. This is a big no-no so make sure you remove the metal ball! And if you have a metal shaker cup like these in this other article, do not use them in the microwave. This post will tell you why I like metal better and which are my favorites.

Second, as I briefly mentioned, when the inside of your blender bottle becomes hot the pressure raises quite a bit. Due to the pressure sealing lid, it is not released until you open it. This could lead to the spraying of hot liquid causing injury or burn. You must always be careful when opening your lid after microwaving a blender bottle or shaker cup.
If you choose to microwave a blender bottle or shaker cup, just make sure you consider the possible effects.

Is It Worth It?
If possible, just use a different type of container to heat your liquids! You may have to wash another dish, but it is always better to be safe than sorry.
If you must choose between coffee or no coffee, then you may feel the need to take the risk as I have!
Just remember to consider:
- Is your metal ball out of the bottle?
- Where is your pressurized bottle pointing? Avoid the burn!
- Is your bottle BPA free? Just in case you could become ill, make sure your bottle is BPA free!
By using my blender bottle for coffee, I simply found another use for the product. It seems that the possibilities are endless!
