Top 10 Best Thermos Reviews

1. Vondior Thermal Coffee Airpot – best thermos for keeping coffee hot

You can keep your coffee and other kinds of beverages hot for up to 24 hours and it doesn’t end there, it can also keep your beverages cold. I like this one in particular because it has a dispenser. Traditional thermal coffee pots normally require pour-over but not this one. The Vondior Thermal Coffee Airpot has a pump-action top, all you need to do is press a button and watch it dispense coffee.

It is made of premium stainless steel material both inside and out which makes it very easy to clean. With an 85 Oz capacity, you can fill up to 15 cups after filling this thermos. Don’t judge its size by the image you are seeing, this thermos is quite big.

Factors To Consider Before Buying A Thermos

Checking these factors before purchasing a thermos through here or anywhere else will help you choose the best of the best.

Size

If you want to go hiking, you’ll need something small, not too large and able to fit your bag. If you are getting a thermos for your family, a large one would be the perfect fit. But be sure to check the dimensions of the thermos before buying it so that your new thermos doesn’t get to contend with your coffee maker in terms of counter space. 

Material

I have seen thermos made of glass, it looks beautiful but I won’t buy a glass thermos, a glass thermos is a water bottle that can’t keep water cold or hot for an extended period. The best kind of thermos is made of stainless steel.

Capacity

Thermoses come in various capacities, the highest I have seen is 120 Oz. If you’ll be filling a whole lot of cups from your thermos, you should get one that has a large capacity to serve all cups. 

Cold/Hot time

Some thermoses can retain heat up to 12 hours and cold for 24 or fewer hours, depending on your preference you should check the thermos’s ability to retain heat or cold.

How To Prime Thermos Before Using It

You need to prime your thermos before adding hot coffee or cold beverage to it, as funny or weird as this may sound it is completely true. Priming here simply means getting your thermos ready. 

If you are going to add hot coffee to your thermos, it is advisable to prime it and you can do this by simply adding hot water to your thermos and allow it to sit for about a minute, then pour it out and then add your hot coffee. The same thing goes for cold beverages, you should add very cold water and allow it to sit for about a minute, pour it out then add your cold beverage. 

Maintenance

Here are some do’s and don’ts that’ll make your thermos last for a long time before needing a replacement.

  • Clean your thermos with warm water regularly.
  • Don’t use bleach or abrasives to clean your thermos.
  • Do not overfill your thermos.
  • Avoid storing carbonated drinks in your flask.
  • Do not use a microwave to prime your flask.
  • Do not put your thermos in a dishwasher.
  • Do not submerge your thermos in water.

FAQs

How long is coffee good in a thermos?
It depends on the kind of thermos you have. If your thermos is completely airtight, it’s insulated walls will help to preserve the heat.

The longer the heat is preserved, the longer your coffee stays fresh. As for cold coffee, it should stay fresh for a long period.

Can I reheat coffee with cream?
No! Reheating coffee will destroy your coffee flavor and taste. If you make coffee and it gets cold before you drink it, you can simply discard it and make another.

Coffee tastes a whole lot better when it is freshly roasted, ground, brewed and served hot. Don’t ever think of reheating cold brew coffee, that would be barbaric.

Are thermos flasks safe?
Thermos flasks are completely safe to eat or drink from, this is, however, dependent on the kind of thermos flask you have. If you have a stainless steel thermos, it is safe to use it. Most thermos made of stainless steel is BPA free.

If your hot drink or food gets cold in a thermos flask, I wouldn’t advise you to eat or drink from it, unless it’s water.

Can you put coffee in thermos?
Yes, you can put your just brewed blazing hot coffee inside a thermos, but you need to be sure the thermos will be able to keep the coffee hot for a long time.

You can alternatively use your thermos as a compartment for storing hot water for coffee brewing.
