Important Camping Thermos Features to Consider
Always consider what you need from a thermos before buying. Is it important to have a drink-from lid? Do you want 24-hour heat retention? Is an attached cup the most important thing? Do you base your decision on construction upgrades, such as added insulation? Make sure you find a thermos that checks all the boxes or you will be less likely to use it long term. If you decide a thermos isn’t right for your camping needs, an insulated camping mug or a camping water bottle may be better for you.
You know a lot about several different thermoses now, but do you know how they work in between their layers? The science behind the products is very interesting and relies on a vacuum chamber.
Thermoses are double-walled, meaning there is an interior wall and an exterior wall with a vacuum chamber in between. This chamber is key for retaining temperature. Picture yourself standing outside in a bus shelter or against a thin wall when its cold. You are typically much colder. When you’re in an interior room removed from the exterior wall, the temperature goes up.
The vacuum chamber uses the same concept. It separates the contents of your thermos from the weather conditions outside, whether its blistering heat or extreme cold. Many also feature additional technology, such as high-tech insulation, to further reduce temperature transfers. By reducing the impact of outside temperatures, your food retains its heat.
Benefits of Using a Coffee Thermos
When you’re backpacking, you can’t just sit down and whip out your camping coffee makers—whether it’s a camping coffee percolator, pour-over coffee maker, or battery operated coffee maker—and your travel coffee grinder without it being an hour-long time investment. A quality coffee thermos lets you prepare your coffee in the morning and enjoy it at a hot temperature throughout the day. Thermoses also help you reduce your impact on the environment by reducing use of paper cups and other disposable products.
The best coffee thermos can be used with any sort of coffee maker. Whether it’s a travel French press or a camping espresso maker. If you’re looking for advice on how to make the best cup of coffee while camping, check out our coffee brewing tips.
How Do I Improve My Thermos Performance?
A thermos will work at some level without any type of preparation. However, you can maximize its longevity by preheating or cooling. If you will be camping in extreme temperatures, definitely invest in this trick.
For hot or cold items, fill the thermos with water at the temperature you need. Reattach your lid and let the water sit for at least five minutes. This helps preheat or cool the interior of your thermos so the metal’s base temperature does not alter the temperature of your food or beverage. Really temperature sensitive? Use heated water to preheat for best coffee thermos performance or use ice for cold beverages.
For thermoses with a pour lid, learn how to use the lid properly. Every time you open your thermos, some of your heat or chill will dissipate. By keeping the lid on, you reduce this seepage.
Precautions for using a Coffee Thermos
Thermoses do keep your coffee hot, so it is always a good idea to practice basic safety precautions. Avoid using included cups walking briskly. The cups typically have a small capacity, and liquid easily sloshes over the rim.
Can I Break My Thermos?
If you know about the potential breaking of thermoses, congratulations! You probably have been around thermoses your entire life or love to buy vintage. But don’t worry. Unless you are using a vintage thermos, you are relatively safe.
Older thermoses were very susceptible to breakage because the interior compartments were made out of glass. Modern thermoses, including many of those on this list, rely on stainless steel interiors and exteriors and are not susceptible to breakage in the same way. That’s not to say you may not cash a cap or attached cup with the right type of fall, but these elements are easily replaced at retail stores. If you buy the best coffee thermos or another top-notch option, a warranty should help you obtain a replacement in the event of a rare product defect.
Side note: That same stainless steel construction makes most thermoses naturally free of BPAs.
How Do I Clean My Thermos?
Most products recommend washing the thermos and component parts in warm soapy water after use. If you use your products for non-mixed beverages only, a gentle swish with a sponge may be all you need. For food use, scrub only with the soft side of a sponge.
Thermoses recommend not using any harsh cleansers, such as bleach, on the product, and to avoid scratching with abrasive scrubbers. Also, avoid mixing powders or foods in the thermos if possible. Premix outside with a milk frother and then pour the liquid or foods in to minimize the trapping of food particles in the seal or seams of the product.
The Thermos Stainless King 68 Ounce Vacuum Insulated Beverage Bottle is the type of product you can use for decades without any difficulty — that is why its the top pick on the list. It features a large capacity, has excellent heat and cold retention characteristics and includes a cap and lid combo to help you minimize heat loss during refills. Its rugged construction makes it the best coffee thermos for the trail, the workplace or daily use on the road, and it can handle a lot more than coffee.
