The Best Answer:

Unlike hot coffee, which becomes stale after several hours, cold brew may be stored in the refrigerator. This should preserve for up to 2 weeks as an undiluted concentration, however, the taste consistency will fade in the 1st 10 days. 

If you water down the concentrate with water, the expiration date is shortened to 5 days.

Cold Brew In Room Temp

I don’t suggest leaving the coffee at room temperature for more than 24 hours since the acidity of the seeds will return and the coffee will have a metallic or powdery flavor. If you leave the cold brew in the fridge, you may soak it for a longer period of time.

Cold Brew And Storage

None of us would advise storing cold brew, even a concentrated, for more than 1 month. Many experts advise avoiding keeping cold brew for more than 2 weeks, though cold brew in concentrated type preserves a bit longer.

What is Cold Brew?

It’s basically black iced coffee with a pleasant mild aroma and sweet, delicate flavors, and with around 200 mg of caffeine per half a liter!

Cold brew is made without using any heating. It is made by resting ground coffee or black coffee in cool, filtered water for several days, which lowers the majority of the harshness, present in drip coffee.

The Preparation of Cold Brew At Your Home!

All you need is black ground coffee, cold water, a French Press or Moka Pot, and a strainer. Spill your coffee grounds into your bottle 1/2 full of water. Immerse this combination for 24 hr.

Using a strainer, filter the coffee. Sprinkle some ice cubes or coffee ice cubes, and ice water to the correct coffee-to-water ratio, and you have a finely brewed cup of cold brew coffee!

Cold Brew Expiration Date

Day-old hot coffee rarely feels as wonderful as freshly prepared coffee. Meanwhile, with cold brew, you may plan to drink your pot for up to 2 weeks after it’s initially produced.

Watered-down cold brew has a storage life of around 5 days before the aroma is forever altered and the drink starts to expire.
