    A coffee thermos is such a great investment. A well-constructed one keeps your coffee toasty hot all day. This is ideal if you want to enjoy your coffee on the go or if you’ve simply brewed too much and want to save some for later. The insulated walls keep the coffee lovely and warm without ever burning it so all that delicious flavor is ready for you to enjoy anytime, anywhere.

    Although a thermos is often associated with hot beverages this isn’t all they’re good for. An insulated flask will also keep iced coffee cold in the summer and stop the ice from melting too quickly.

    There are so many good reasons to have one of these but the problem arises with the fact there are almost too many out there to choose from. To help you out, here are ten top picks to help narrow down the options to a manageable volume.

    I’ve got options to suit every need so have a browse through and you’re bound to find one that suits you. I’ve included all the basic criteria so you can easily compare options with a quick glance. Have a browse and if you like the looks of any of these click the ‘Price and Reviews’ button to check current prices on Amazon.

    Now let’s get stuck in and look at our top choice today, the Stanley Classic. A rugged thermos that ticks every box!

    1. Top Choice – Stanley Classic Vacuum Insulated Wide Mouth Bottle

    Stanley Classic Vacuum Insulated Wide Mouth Bottle

    Brand: Stanley Classic

    Size: 35.2 Oz, 64 Oz options

    Color Option: Hammertone Green

    Leakproof Lid: Yes

    Coffee Mug Included: Yes

    Price & Reviews

    The Stanley Classic vacuum bottle is a big winner when it comes to functionality. It’s made from durable, rust-proof stainless steel so is hard-wearing and easy to keep clean. All plastic is BPA free and the double-wall vacuum insulation keeps your coffee hot for 24 hours. Now, this isn’t lukewarm, or tepid, it really keeps drinks scalding hot. It also prevents ice cubes from melting for up to 5 days if left sealed.

    The lid design is not only splash-proof but completely seals the thermos so you can throw the whole thing in your bag and not have to worry about leaks. The wide-mouth design makes it easy to fill and serve your coffee. It even comes with an 8 Oz mug that screws on top so you can enjoy a hot cup of coffee any time, anywhere!

    This option really is a superior design for heat retention and spill-proof features. You can use it for hot drinks or cold drinks and one of the best coffee thermoses out there. The only downside (if you can call it that) is that there’s only one color option so you can’t get creative with the design. This option also comes with a lifetime warranty so it’s a risk-free purchase through and through.

    2. Runner Up – Hydro Flask Coffee Travel Mug

    The spill-proof lid is BPA-free, phthalate-free, and fits into your car cup holder making it really convenient to use. It’s also dishwasher safe so super easy to keep clean.

    Coffee Thermos Buyers Guide

    Size

    The first main consideration when buying a coffee thermos is the size of the flask you’ve chosen. It needs to be big enough to hold all the coffee you wish to consume over the day but if it’s too big then it won’t insulate the coffee as effectively.

    If you’re brewing directly into your thermos then make sure it’s not too big to fit under the coffee makers brew head. The final thing to consider is the width of the flask and whether it’s comfortable to hold and will it fit into a cars cup holder if you like to sip coffee as you drive.

    Measuring up the internal and external requirements you have for your thermos will save you a lot of hassle later on.

    Insulation

    A vacuum insulated thermos is the best choice. These have superior insulating capabilities compared to ceramic or similar ones. The vacuum layer prevents any heat from escaping and the outside of the flask will be cool to touch. This also prevents condensation from forming if the flask is being used for ice-cold beverages.

    Lid

    The design of the lid can make or break how you use your coffee thermos. Make sure you choose a leak-proof and spill-proof design with a screw lid as this seals in all the heat and doesn’t compromise the insulating capacity.

    Some lids come with an easy-sip spout which can be useful for on-the-go use and some come with a coffee cup attachment so you can serve the amount of coffee you want and enjoy it this way. A wide top can be very helpful for filling up your thermos or if you plan to brew coffee inside the flask.

    The design of lid you choose will reflect how you use your coffee thermos so make sure you choose one that best suits your needs.

    Clean it First

    It’s really important to clean your thermos before you use it for the first time. You can do this using soap and hot water and make sure you clean each part well. Rinse it thoroughly several times with fresh water to make sure you get rid of any suds. Let it air dry and you’re good to go. You can use a dishwasher to clean it only if the manufacturers label it as dishwasher safe.

    Remember to Pre-Heat

    Before you add hot coffee or iced coffee to your thermos it’s essential to prepare the flask. Pre-heat it with boiling water for 5 minutes or cool it with ice before you add your coffee. Doing this simple step will make a massive difference to the temperature retention of your coffee and will improve your whole day.

    F.A.Q.s

    Which coffee thermos stays hot for the longest?

    The Stanley Classic thermos keeps drinks hot or cold for 24 hours which is way longer than your average thermos. It can also keep ice cubes from melting for up to 5 days which is very impressive.

    What’s the difference between a coffee thermos and a travel mug?

    A coffee thermos is a sealed flask that prioritizes the insulation of liquid. They are completely sealed so you can carry them in a backpack. They are perfect for enjoying coffee all day at work or for hiking or camping trips.

    A travel mug is a mug-shaped device that has insulated walls. They keep your coffee hot for longer than a traditional mug and allow you to easily sip and enjoy your coffee as you travel. The downside is they don’t maintain the temperature of your drink for as long as a thermos although they are easier to use.

    Can my thermos go in the dishwasher?

    The general rule with most thermos’ is that they don’t do well in the dishwasher. Some brands may be dishwasher safe but always check the manufacturer’s instructions beforehand.

    What’s the difference between spill proof and leak proof?

    Spill proof means that the lid is watertight against splashes and won’t leak if you carry the coffee flask upright. Even if a thermos is spill proof it may not be watertight enough to turn upside down or carry in a backpack. Leak proof means if you knock the flask over it won’t leak and it’s completely watertight so is much more secure than a spill proof option.
