How Does Coffee Go Bad?
There are 2 factors：
-
When the coffee comes into contact with bacteria, the coffee goes terribly, which leads to poor taste.
Therefore, after the coffee is extracted or brewed with hot water, the bacterial content in the fresh coffee is very low, as the hot water can over-achieve the sterilization effect. Therefore, the taste of freshly brewed coffee is the best.
Similarly, the bacteria in the environment will decrease with the temperature of the coffee until it reaches room temperature. This also verifies the answer to the question “How long can coffee sit out”, why 4-6 hours? It is because the bacteria in the environment adapted to the room temperature will enter the coffee, which means the coffee breeds bacteria. It also explains why coffee's taste deteriorates after being stored at room temperature for some time.
-
Carbon dioxide gets into coffee and makes it bitter.
The volatile compounds in coffee mean its flavor is time-sensitive, and the longer it sits, the less pronounced the taste may be. Additionally, as the coffee sits, carbon dioxide from the environment dissolves into the coffee, altering its chemistry and increasing its bitterness. As a result, the taste of coffee exposed to room temperature changes and can become bitter. It also explains the question, “How long can coffee sit out?” and why it is recommended to drink it within 4-6 hours of freshness.
How long can coffee with creamer sit out?
Mocha with cream is suitable for most people's tastes, it doesn't have too much of the bitter flavor of coffee, and it's not as sweet as chocolate. So how long can you store coffee with cream? It storage time is recommended to be 3-4 hours, this is because the cream is made by whipping light cream, which contains milk, it is easy to harbor bacteria, thus causing it to be put into the coffee will make the coffee easy to deteriorate. When coffee containing cream is stored indoors, the bacteria will grow faster when the coffee temperature is close to room temperature. However, our S3 PRO+ Smart Mug provides a constant temperature heating function that prevents bacteria from growing at high temperatures, which means that your mocha with cream can be stored for a longer period.
How long can coffee with milk sit out?
Similarly, your latte will be made by adding milk to coffee, and the milk in coffee makes it faster for bacteria to grow. Therefore, store coffee with milk intelligently for 3-4 hours.
