Coffee Thermos Buying Guide & FAQ
We took a lot of aspects into consideration when selecting which coffee thermoses to include in this guide. From reviews to practicality to quality, each thermos was tried and put to the test with our strict guidelines. This was no overnight process, and we’re still bouncing off the walls from all the deliciously warm coffee we consumed throughout. Nevertheless, only the best coffee thermoses made the cut, and we feel confident that you’ll find the perfect one for you within this guide. Read on to discover more about coffee thermoses, so that you get the most out of your very own.
Features To Look For In Thermoses
Coffee thermoses have risen in popularity in recent years, but we’re really not surprised. With the sole purpose of keeping drinks warm, they are a practical thing to own. However, when it comes to certain features to look out for, it will completely depend on what you’ll be using the thermos for. For example, daily commutes mean that travel-sized coffee thermoses are perfect, but camping trips with multiple people may require something larger. It doesn’t just stop at size either. Below, we unravel the main features to look for in thermoses.
Construction - The construction of your coffee thermos is very important, as if you’re travelling around, you’re going to want something which is lightweight and easy to carry. Thermoses with a plastic outing are usually the best for this situation, but if you aren’t fussed about the weight and want something more durable, then a stainless-steel outer will be the best option for you. More times than not, the highest quality of thermoses will feature both stainless steel and plastic aspects. Usually, the stainless steel will act as an inside layer keeping the heat in, and the plastic outer will act as another layer of protection while also adding a more lightweight feel. If you’re looking for a thermos which comes in lots of different colours and patterns, then you’ll probably have more luck looking at bottles with plastic exteriors. Either way, both materials will be extremely durable and made to last.
Insulation - The top three materials used in high quality thermoses are stainless steel, glass, and plastic. We recommend opting for stainless steel, as this will retain heat the most effectively and avoid corrosion troubles. Although stainless steel thermoses might be slightly pricier, they’ll last far longer and save you money in the long run. After all, the main point of the thermos is to keep your drink warm, so the quality of insulation needs to be perfect.
Another top tip when it comes to insulation is to check how long the thermos will insulate for. Some may only keep your beverage warm for a few hours, whereas others can last over a day. It’s important to check their lifespan so that you aren’t faced with disappointment if the thermos does not perform as well as expected.
Handle - Do you intend to use your thermos while moving about? If so, then a handle is a very useful feature to look out for. Handles are usually more common on thermos mugs, but some tumblers even have them now. It’s all about preference, but if you prefer to drink your hot beverages with a handle, then settle for no less and get a thermos with one.
If you can’t seem to find a thermos with a handle that matches your needs, then it’s worth looking into magnetic handles which can simply attach to your pre-existing mug. This won’t be doable with all thermos mugs, but it’s definitely worth looking into if you’re adamant about having a handle.
Cap & Clip - The very best thermoses will be vacuum sealed and finished with a cap, meaning there is absolutely no risk of your hot drink leaking everywhere. If you want to be extra careful, then purchase a thermos which has a clip attached to it, so that you can clip it wherever you like and never let it roll out of sight.
Also, if you’re more of a mug drinker than a bottle drinker, then look for a cap which also doubles up as a mug. This is quite a common feature for thermoses to have, so you won’t struggle to find one, but it will be an absolute lifesaver on your travels when you want a more civilised way of drinking!
Volume - The volume of a thermos relates to how much liquid it can hold, and once again, the volume you choose will depend on your preferences. If you’re a coffee-addict and constantly drinking throughout the day, then you’ll benefit from a large volume. However, if you only have coffee for your commute to work, then a smaller volume will keep you satisfied. It’s important to carefully consider the volume you purchase, as the last thing you’ll want is wasted liquid which ends up staining the thermos and going stone cold. That would be enough to put you off drinking coffee for life, and we know you don’t want that.
Size - As well as the volume of the thermos, the overall size of it is important too. Do you need something which can pop in your bag, or are you happy carrying a larger mug around? Think about size in terms of practicality and you will be able to make an informed decision on what will be best for you. For personal use, we recommend using a smaller thermos, but if you’re providing drinks for an event or multiple people, then the larger the better!
Durability - Coffee thermoses are made to be portable, meaning they need to be able to cope with a few bumps and scrapes. We’ve all dropped a drink at some point in our lives, and there’s nothing quite as heart breaking as dropping a mug of freshly-brewed coffee. When it comes to durability, stainless steel thermoses are the way forward, as this sturdy material won’t be breaking on you anytime soon. As well as this, single-use plastics are becoming a huge warning sign in recent years, meaning it’s important that you’re actively improving your footprint on our planet. Coffee thermoses are a great step in the right direction, as the majority will be sure to last years, if not for life. So, not only will you be having a great sip of warm coffee wherever you go, but you’ll also have a sense of accomplishment as you realize you’re saying goodbye to single-use plastics and hello to a greener way of life!
Coffee Thermos FAQ
Q: How long does coffee stay hot in a thermos?
A: The length of time that your coffee stays hot in a thermos will entirely depend on how it is made. As a rough guide, the majority of high-quality thermoses will keep beverages warm from anything between 4 and 24 hours. The length of time they stay hot will reflect in the price, but it’s all worth it for an enjoyable brew all day long.
Q: Are thermoses dishwashers safe?
A: Whether a thermos is dishwasher safe will entirely depend on the material it is made out of. However, it is advised to not put a thermos in a dishwasher unless the whole product is made out of stainless steel or plastic. For safe cleaning time and time again, simply fill the thermos with boiling water and baking soda, and any stains will vanish in an instant.
