For the best taste, drink it within a week. When the week is done, just throw out the remainder because it would be old, and the flavor of the coffee would be lost. Stumptown, however, claims their bottled cold brew will last around 14 days.
But what happens to the caffeine content in your brew?
Caffeine levels in regular coffee are higher than in cold brew. The more caffeine is taken from the coffee beans and into your coffee, the hotter the water. This implies that at a high temperature, more caffeine dissolves. Because cold brew is brewed with cold water, it has less caffeine than hot coffee.
But, if cold brew coffee contains 2 times more coffee-to-water ratio than standard cup coffee, does it mean you’ll get more caffeine than traditional cups?
No, Dilute it with an equivalent amount of milk or water before you drink cold brew concentrate.

How Should Cold Brew Be Stored?
The procedure for keeping cold brews is straightforward.
You may keep it in any container you want: a plastic pitcher, a glass jar, or a stainless steel container with a top and straws on the side for convenient sipping.
For the best flavor preservation:
- It must be kept in an airtight container.
- The temperature in the storage compartment must remain at or below 40°F.
- If it is not immediately ready for drinking, chilled cold brew can be stored on ice (as long as there is a lid). As a result, make sure you have enough freezer space.
- When transporting the cold brew, store it in an ice-filled cooler.
- Do not let the cold brew out for longer than two hours at room temperature.

Refrigerate cold brew if you want to drink it for a few days.
