Editor’s note: The Camelbak – Forge was discontinued in 2018, and we’re sad to say that it hasn’t been replaced with an equivalent design. Our original review is preserved here for posterity.) Worse still, even when the stopper is in the closed position, it leaks. It’ll keep dribbles from coming out if you turn it upside down, but as soon as you drop it on the floor or shake it around it’ll let drips out. The slider switch is fairly easy to use, but it’s also vulnerable to getting bumped open inside a bag; this mug did poorly in our tumble test. The Klean Kanteen is still a drink container we like, but it’s not easy to open and close with one hand (and in fact took a fair bit of effort to open with two hands), and it has more parts to disassemble for cleaning than any of the other mugs. Thermos – Stainless King Travel Mug Keeping a mug clean is one of those tasks that makes the difference between “buy it for life” and trashing an expensive mug in disgust. Our rating here is based on hand-washing with a sponge, scrubber, or bottle-brush, but we’ve also noted if the manufacturer says you can put the whole mug in the dishwasher. For secure carry in a bag, the Transit was better than most, but it did leak a teaspoon worth after half an hour in a spin-cycle.

Mugs like these are great if you want to keep drinks hotter for longer. Just be sure you cool your coffee or tea before adding to the mug, or pour out your beverage to drink until temperatures inside the mug have reached a safe level. Cup holder/single-brewer compatible: For those looking for compatibility with a single-cup coffee brewer, we’ve noted which mugs are seven inches or shorter (typical height for a single-cup brewer when the drip tray is removed; your machine may vary), and whether a “shorty” model (usually in 12 oz capacity) is available. File Types– It doesn’t have to be a specific file type at this stage, but we prefer vector .ai, .eps or .pdf files. Don’t worry if this doesn’t mean anything to you, we can work with almost any file type so just send us what you have to hand. After 30 minutes, 50ml of water was decanted from each mug into a 100 ml pyrex beaker every 15 minutes. With a bench thermometer and K-type probe, we took eight samples from each mug, leaving a slightly larger sample at the end. This controls for the way most of us drink away the specific heat capacity of the water in our travel mugs if we sip periodically over the course of a commute or while working at a desk. If you need your drink to stay hot for an entire day and you don’t want to fill a giant thermos, the Thermos – Sipp is a fantastic mini-thermos you can drink from with one hand.The Contigo Autoseal system is great for convenient spill-free sipping, but its springs and levers are immersed in your pumpkin-spice foam and nutmeg sprinkles.

Studies show that the severity of burns starts getting significantly worse at temperatures above 175°F, so temperature curves between 200°F and 175°F aren’t showing anything but a danger zone. A study published in the Journal of Food Science shows that most people will mix cream/milk (or colder coffee) into their hot coffee to bring it down to around 140°F if they’re going to drink it immediately. Further, the Specialty Coffee Association of America cupping and tasting protocols recommend that evaluation of flavor should not begin until coffee has cooled to between 160 – 140°F.

We included one non-steel mug in our lineup, the Ello – Mesa double-wall ceramic mug. We looked at other popular ‘reusable to-go cup’ designs, but none of them had spill-proof lids or insulating properties that would make them competitive in this line-up. (Some issues, like reports of a smelly latex rubber lid on one popular brand, or lids that were difficult to snap on, made our choice not to test even easier.) One of its standout features is the comfort handle, which provides a secure and ergonomic grip, ensuring you can comfortably hold and carry your favorite beverages. The mug also boasts a secure, splash-proof lid, keeping your drinks safe from accidental spills.
