Why coffee lovers should always use a glass thermos instead of an aluminum one

JOCO To-Go Coffee Cup, $26.95, available at Urban Outfitters.

We don't have to tell you that using a reusable thermos for your morning cup of coffee over paper cups is always a smart idea: they're a much more cost-effective and environmentally-friendly option than paper.

But something you may not know is that all thermoses are not created equal. There's a major downside to drinking coffee that has been stored in a metallic vessel: altered taste. The container tends to impart some unwanted flavors into your craft brews -- this is the same taste you can expect if you've ever drank water from an aluminum water bottle.

The easy solution is glass. JOCO cups have tapped into this idea, creating high-quality glass vessels that won't "affect flavor so you will taste your coffee or tea, not your cup." Designs are also free of harmful chemicals like BPA, lead and cadmium, and are microwave and dishwasher-safe.

But the best part? They keep your coffees nice and steamy for hours on end.

It's the ultimate tool to ensure that your cappuccinos, flat whites, and even Americanos stay flavorful and pipping hot during your morning commute.

And if you're a serious coffee enthusiast, the $27 price tag will be worth every single penny.
