How long does cold brew coffee last in the fridge?
If the cold brew coffee does not have any additional milk or cream topping then it can last approximately one week in your fridge without going bad as it is only a mixture of water, sugar, and ground coffee and these things do not go bad that quickly.
One more thing to consider is to always use an airtight container or bottle to store the coffee so that it will not pick the smell of other foods placed in your fridge as no one will ever want to consume melon scented cold brew coffee, right?
How long does cold brew coffee last at room temperature?
The cold brew coffee will not taste the same if you drink it after putting it for more than a day out at room temperature. Another thing to consider is that the cold brew coffee should be kept in airtight thermos or container or else the oxidation reaction would make it stale which continues even after the coffee is brewed.
The chemistry of coffee oxidation
When the coffee beans come in contact with the air they are oxidized and same is the case for the cold brew coffee that is left in open for some time. This oxidation reaction significantly affects the aroma and the flavour of the coffee with no significant change in the colour of the coffee.
Brewing coffee itself is the oxidation reaction. At the point when the coffee beans come into contact with water, they will start delivering their aromatics, oils, and acids into the water giving you an enriched and flavourful coffee but if the process of oxidation continues even after that it will result in a really sharp and bitter flavour and that is not something we want.

How to make cold brew coffee?
Brewed iced coffee is made by soaking coffee in 40 degrees hot, filtered water and afterwards placing it for approximately 24 hours in the refrigerator. After the completion of 24 hours, you sift it through, and voila! you have your freshly made brewed iced coffee.
One thing to keep in mind while making cold brew coffee is that the longer you let the coffee beans sit with water, the more enriched the flavour of your cold brew coffee.
