    Here's How Long Your Morning Coffee Is Actually Good For

    Learn about old coffee in all its forms—this is a safe space.

    It happens every afternoon: Around 4 o'clock, I start to fade and begin considering my half-consumed coffee at my desk.

    And every day, I wonder, "Can I drink that?

    So I turned to Google to find an (unofficial, but workable) answer to all my late-in-the-day-coffee questions.

    What if the coffee has milk in it?

    Is the flavor of the coffee affected?

    Will microwaving the coffee kill bacteria?

    Does the water in the coffee spoil?

    So, is coffee safe to drink after several hours?

    Bottoms up!
