Although it is possible to successfully cold brew coffee at room temperature, we don’t recommend it because there is a greater risk of bacteria developing.
What is Cold Brew vs Iced Coffee?
The difference between cold brew coffee and iced coffee is how they’re brewed.
Cold Brew Coffee is brewed in the refrigerator overnight. It uses cold water and coffee grounds that are soaked in cold water and later strained out to create it.
Iced Coffee is brewed using hot water and poured over ice cubes to make it cold. To keep from diluting your iced coffee, it’s best to prepare your ice cubes in advance by pre-freezing already brewed regular coffee in an ice cube tray, rather than using water.
That way, when the ice cubes begin to melt, it will simply add to the coffee flavor rather than diluting it with a water flavor from water made ice cubes.

3. Keep it in an airtight glass container in the refrigerator that’s set to 40F degrees or less. Using glass such as a mason jar with lid provides the best results, compared to a plastic container.
4. Use cold brew ice cubes or coffee ice cubes to help keep from diluting your coffee and to keep contaminants out. This will provide a longer shelf life.
5. Add cold brew preservatives to the coffee oils, if desired, to make it last longer.
5. Leave the cold brew concentrate as undiluted concentrate while storing it in the refrigerator.
Will Sugar, Cream, or Milk Impact the Shelf Life of Cold Brew?
Yes, the addition of sugar, cream, or milk will likely shorten the shelf life of this type of coffee as well as iced coffee. Its presence causes bacterial growth to take place more rapidly, which causes it to spoil faster.
For the best results, and to maximize shelf life, avoid adding sugar and creamer to your cold brew until you’re ready to serve it. This will help to keep it fresh for as long as possible.
