We're probably not the only ones who can't imagine a morning without a cup of coffee, but we're also probably not the only ones who don't empty the cup regularly. Either time pressure forced us to do it, or something interrupted our morning ritual and we simply forgot about it. But can you later drink the coffee you didn't finish drinking in the morning? Is post coffee safe to drink? Does it keep the same taste?
It's time for the afternoon dose of caffeine, but you still have it left half drunk coffee since morning. Is it safe to drink or should you brew a new one? Pour it down the throat or drain? A dilemma that has probably struck many people, but he never really dealt with it. The answer to the question can you drink coffee later, which is in the morning you didn't sleep all the way, is simple, but depends on whether she was coffee with or without milk.
What if it's coffee with milk?
If you drank it with milk, it is better to have it fresh. You can keep milk in the refrigerator for more than a week and everything will be fine, but milk at room temperature is not good for more than a few hours. Some say that only two, while others say that it should last from 5-6 hours before the "invasion" of bacteria. That's why you'd better make a new cup of coffee, because it might have already made its way into the cup in the meantime.
Is the taste of coffee at risk?
Coffee beans turn yellowish after about two weeks, while roasted coffee starts to taste bad after just 30 minutes. After this period, you still have about 4 hours before the oils of the coffee beans start to spoil - among them, caffeol is the one responsible for coffee's aroma and taste - which further changes the original taste.
Can the water in the coffee spoil?
Water can absorb flavors from the environment, changing its taste (especially if you leave it in the fridge), but even an uncovered glass of water is still drinkable for a week after it's poured. Therefore, unless there is basically nothing floating in the water, the bacteria will not settle here.

So is it safe to drink stale coffee?
The verdict is as follows. Black coffee definitely, although it probably won't taste as good as it did at the beginning. If there is milk in the coffee, it is better to brew it fresh. But if you are determined to finish this one as well, for greater safety, put it in the microwave first so that it destroys as many possible bacteria floating in it as possible.
