Tips for Choosing a Coffee Thermos

A thermos is a double-walled water bottle that looks just like any regular water bottle but comes with a special purpose: it retains the temperature of whatever you put inside it. Thermoses can be extremely useful for people who commute daily and want to take their coffee with them when they’re on the go.

Making sure you buy the right coffee thermos is essential since it’s a product you probably plan on using a lot. When choosing one, look for a thermos that’s reliable and easy to use, with the right size and capacity.

Here are a few things to look out for when choosing the right coffee thermos to ensure you get the best product for your money’s worth.

1- The Size and Volume

Before you buy your coffee thermos, think about what size and volume you need. Perhaps you’re someone who likes to sip and savor your coffee all day long. If so, don’t go for the smallest one on the market.

On the other hand, if you’re the type of person who enjoys a single serve, there’s no use in buying something with a large capacity that’s too bulky.

It’s important to consider how much coffee you’d need to carry around with you so that you can choose the size and the volume of your thermos based on your needs.

2- Insulation

Thermoses with vacuum insulating technology are far better than they used to be for keeping your coffee hotter for longer.

Check out the heat retention and shelf life of your thermos which is important especially if you want one that’ll keep your coffee warm all day long instead of for a few hours. Some products feature double-walled stainless steel construction that adds the benefit of preventing your bottle from sweating.

3- The Delivery System

This is one of the most important features to consider when choosing your thermos. The last thing you’d want is to be spilling hot coffee all over you while you’re on the commute to work so think about the delivery system of the beverage.

If you prefer, you can go for a thermos with a detachable drinking cup that doubles as a  lid. This is convenient since you don’t need to worry about searching for cups.

Some thermoses come with a sipping hole, or adjustable mouthpiece and some even have a simple twist-and-unscrew lid. Think about what you prefer which would make it easy for you to operate, seal and store your thermos especially while you’re travelling.

4- Leak Proof/Spill Proof

These features are not 100% guaranteed in any thermos so it’s a good idea to check this before you buy one or you might just end up with coffee all over the inside of your bag.

Make sure that you go for a product which you know has been drop-tested and comes with a proper, leak-proof seal before you buy it.

5- Materials and Construction

Consider the materials used for construction. Ensure that the thermos is made of BPA free plastics and non-toxic materials.

How to Care For and Maintain Your Thermos

Here are some simple tips you can follow to maintain your thermos and keep it clean. This will keep it functioning at its best and lasting longer.

  • Don’t overfill your thermos. Make sure there’s always enough space to fit the stopper properly.
  • Don’t heat up your thermos in the microwave as these bottles are typically made of stainless steel.
  • When cleaning, rinse with warm water if you haven’t used the bottle in a while.
  • Submerging the thermos in water can make water leak in between the liner and the bottle, so avoid doing so.
  • Don’t use harsh chemicals like chlorine bleach to clean the thermos since it can damage the steel weld.

Easy Ways to Clean Your Thermos

If you don’t clean your thermos properly, it can end up smelling bad and tasting weird. If you don’t have a bottle brush, you’ll find that it’s hard to get into the bottom of the bottle to clean it adequately. But there are other ways to clean a thermos and they don’t require a bottle brush.

  • Tea Bags – You can use tea bags to clean your thermos. Put the tea bag inside the thermos and add some boiling water to it. Fill up the bottle and leave the tea bag overnight. Throw away the bag and the water the next morning. Typically, this should result in a clean and sparkling thermos.  
  • Baking Soda – This is another natural product to clean your thermos with. This is an affordable and easy method of cleaning your thermos. Simply mix 1 tsp of apple cider vinegar and a teaspoon of baking soda with warm water and let it sit in the bottle for a few hours. Then scrub and rinse well.
  • Vinegar – This is another great way to clean thermoses and to get rid of the smell that tends to linger inside them. It removes soup and coffee stains easily and the usage is simple. Just mix vinegar with ice cubes or some warm water and shake it for a couple of minutes. Then scrub the inside of the bottle with a brush and rinse.
  • Dishwasher – Some thermoses are safe to wash in the dishwasher but check if this is the case before you put the bottle in the dishwasher, to avoid damaging your thermos. Dishwashers are excellent ways to clean thermoses because they sanitize the bottle at high temperatures. It’s a good idea to give the thermos a rinse before putting it in to remove any particles that may be there.
  • Soap and Water – Using a mild soap or detergent and water is the easiest way to clean the thermos. Simply put some soap in and fill the bottle halfway with water. Close the bottle with the lid and give it several good shakes to ensure that the solution removes particles and reaches all parts of the interior. If you can disassemble the lid and other components, that’s excellent as it allows you to remove gunk that can gather in those areas.
  • DO NOT USE BLEACH – Using bleach to clean your thermos is a sure fire way to damage the product. Bleach is harsh and hazardous to thermoses, as it can strip the materials. Use one of the safer options listed above to clean your thermos without damaging it.

Cleaning and maintaining your thermos is the best way to increase its durability while also ensuring that it’s germ-free and safe to drink from. Taking reasonable care of your thermos ensures its longevity and makes the most of your investment.

The Bottom Line

Whether you’re looking for a basic tumbler to keep your coffee hot while you commute, or for a heavy-duty thermos that’ll keep your drink hot or cold for over a day, there’s a product out there for you.
