Frequently Asked Questions (FAQs)

1. Can you use a food flask for hot drinks?

But this bottle works just as well for hot drinks as cold. ... We tested the bottle's impressive claims of keeping hot drinks hot for 28 hours and cold drinks iced for 92 hours and it lived up to both.

2. Can you put hot coffee in a flask?

Hot coffee can go in a Hydro Flask without causing it damaging or changing the flavor. Coffee is not very acidic and coffee with milk even less so. The acidity levels are not high enough to react with or corrode the stainless steel.

3. Can you put hot tea in a flask?

If you're making tea in a flask, it's surprisingly easy to end up with something bitter and curdled. ... Brew the tea in a different receptacle before you pour it into a preheated flask. And always, if you can, take a separate container of milk.
