Cold Brew

Definition

Cold brew is a coffee brewing method that uses cold or room temperature water and an extended steeping time (12-24 hours) to extract coffee compounds. Unlike iced coffee (hot coffee poured over ice), cold brew is never heated, resulting in a smoother, less acidic flavor profile. It uses coarse ground coffee and produces a concentrated coffee that can be diluted with water or milk. Cold brew has lower acidity, making it easier on the stomach, and typically has higher caffeine content per serving due to the longer extraction time and higher coffee-to-water ratio used.

Common Mistakes

  • Using fine grind (should be very coarse)
  • Steeping too short (needs 12+ hours)
  • Not filtering properly (leaves sediment)
  • Storing at room temperature too long (can spoil)
  • Using wrong coffee-to-water ratio
