Safety of coffee in thermal flask, long periods of time
How long is it safe to hold coffee in a thermal flask? Is coffee (prepared in a cezve, Turkish method, no sugar) carried in a thermal flask for 24 or 48 hours still safe?
I'm asking because black tea, for example, goes really bad in just a few hours.
Best Answer
Coffee in a container is approximately as safe as boiled water in a container. While it may be unpleasant tasting, the water in coffee and tea is almost universally boiled, and the scalding liquid is placed directly on the grounds/tea leaves. There is a little nutritional value in coffee and tea extracts, providing some support for new microbes introduced after the boiling, but not much.
There is no reason to be wary of coffee kept in a clean, sealed container for a day.

Answer 2
While it is perfectly safe, I suggest you shake it up a lot before drinking. It also may not be very tasty, sorry to say, after sitting for 24 hours.
