Any avid coffee drinker will tell you that there are few things worse than taking a sip of coffee and finding it has gone lukewarm or cold. Investing in the best coffee mug to keep your coffee hot is important to those who like to savor their hot coffee and take a little time between sips. Making sure a mug retains heat from the get-go is the first step to the perfect cup.

The reason your coffee cools down is a matter of basic physics. According to the laws of conduction, when hotter molecules collide with cooler molecules, they transfer their heat energy to the cooler molecules.

The air near your coffee is warmer than the air further away from your coffee, so every time you pour yourself a cup, your hot coffee’s molecules are exposed to the cold air around you and in the mug.

The ultimate goal of your coffee mug is to limit exposure to cool air and contain heat. Here is the best coffee mug and travel coffee mug list to help to keep your hot beverage satisfying and tasty.

Buyer’s Guide

Most people may not give a lot of thought to choosing their coffee cup or travel coffee mug, but if keeping your coffee hot is important to you, then it’s imperative to consider some of the following factors to make the best choice. The right material, design, structure, and aesthetic can make or break your coffee-drinking experience. Here is a list of some things you should consider before purchasing your mug.


The right material is probably one of the most important things to consider when purchasing a coffee mug. Each type comes with its advantages and disadvantages, so you should choose one based on your personal preferences.

Ceramic cups are a great choice if your number one goal is to enjoy a hot coffee in one sitting. A ceramic coffee mug also leaves no unnerving metal after-taste like some of the other models available. A ceramic coffee cup is more fragile and is not the most practical to carry around throughout the day. These are best if you just want to enjoy a coffee at home.

Glass cups are another great choice if you want something that will retain the original taste of your coffee. A glass coffee mug is also a prettier option and is fun to drink from. A glass mug generally performs worse when it comes to heat retention, but this varies from model to model.

An example of some great looking glass mugs are shown below

Hard plastic is a great option if you are someone who is very environmentally conscious since they are often made from recycled materials. They are also great for heat retention and last for a long time. A lot of users think that they can leave you with a funny smell and noticeable after-taste. Plastic mugs still make a great option for travel.

Stainless steel is another great option often used for a travel mug or coffee thermos. Double-walled stainless steel is one of the best when it comes to retaining heat for long periods, making them ideal for traveling. You should keep in mind that stainless steel can get dented if it hits hard surfaces and those dents are almost impossible to smooth out.

Some shiny stainless steel also attracts fingerprints so you may find yourself cleaning it more often. One solution is to go with a brushed stainless steel finish as this will help you keep the fingerprints away and reduce the time amount of cleaning.

As for the inside of the mug, you should find one that is non-stick so that you receive the pure taste of your coffee without any additional unpleasant taste.

Over time, some less-durable models sacrifice this feature so be sure to read the reviews to make ensure this does not happen. Lastly, you should check if your model comes with a warranty, as this is often a good indicator of its quality.

Easy Carrying & Comfortable Holding

You are going to want a mug that is convenient for you to hold and carry around. The right coffee mug will come with a proper handle made of graspable material to make your life easier every time you take a sip. Also, the best mugs should retain heat without making the outer surface of the mug too hot to hold or touch.
