Iced coffee is thickened coffee than the regular coffee we drink every day. Usually, it brews with hot water while putting in the double amount of ground coffee. This concentrate is called base coffee and serves with ice cubes. Since Iced Coffee mixes with ice, it has to be a concentrated base.

It brews hot because sweeteners can readily melt at this temperature. Ice cubes or chilled water dilutes it as well as cools it down immediately.

This drink will last 2-3 days if kept in an airtight pot. In this way, the life of iced coffee extends. But, always check the smell and color before drinking for safety purposes.
  • Case-2: If you brew the concentrate (the base coffee) or bring it from cafes, it will last longer. Close the lid of the coffee container so that it has no contact with air. Place it in the fridge as soon as possible. It will be in good condition for 1-2 weeks. Check the smell, taste, and color each time you use the concentration.
