How Long Does Brewed Coffee Last?
|Brewing coffee (under normal temperature)||12 Hours|
|Brewed coffee in the refrigerator||3 to 4 Days|
The time the brewed coffee lasts depends on several factors. Some of them are temperature, the time for which it is exposed to air, and mainly how it is kept. The good flavor lasts nearly half an hour.
If it is kept for few hours, then at first it loses its fragrance. Slowly it starts developing rancidity. Then it starts to taste more bitter and sour. The plain black coffee stays fresh for longer than brewed coffee. It can stay fresh nearly for a day-long without becoming stale.
Milk-based drinks do not stay fresh for long. Milk is perishable. It can go bad very quickly. In due course, milk starts curdling and tastes sour. Some such milk-based drinks are latte, mocha, frappuccino, etc. These all do not stay fresh for long. It is wise to through them instead of consuming them.

Why Does Brewed Coffee Last That Long?
The main reason why the coffee goes stale is due to oxidation. Coffee is a highly aromatic compound that oxidizes very fast when it comes in contact with air. If it doesn’t come in contact with oxygen then it may stay for a little longer.
Coffee brewing is a long chain chemical reaction. When the coffee gets in contact with hot water it starts releasing. If the water is too hot then it will over-extract the coffee and taste more bitter. The smell will also go very fast at such a high temperature. So 45-60 degrees Celsius of temperature is recommended for a better brew.
The oxidation doesn’t stop after brewing. It constantly gets exposed to oxygen and continues to break down with some of its molecules. Though it would be safe to drink, its aroma and flavor start fading.
At high temperatures, the process becomes faster. The flavor ff brew stays for long as compared to the hot brew. Hot brew tastes more bitter. When kept in the fridge the oxidation process slows down.
An airtight container is preferred so that it does not absorb other favors.
