Quick Answer

To make cold brew at home, combine coarse coffee grounds with cold or room-temperature water, steep for 12 to 18 hours, strain through a filter, dilute the concentrate to taste, and refrigerate it in a sealed container.

Ingredients and Tools

  • Coarsely ground coffee
  • Cold or room-temperature water
  • Jar or pitcher
  • Spoon
  • Fine strainer
  • Coffee filter or cheesecloth
  • Sealed storage bottle

Safety Precautions

  • Use clean containers and filters.
  • Refrigerate finished cold brew promptly.
  • Do not leave brewed coffee at room temperature for days.
  • Use caution with glass jars in crowded refrigerators.
  • Label strong concentrate so it is not mistaken for ready-to-drink coffee.

Step-by-Step Instructions

  1. Step 1

    Use coarse coffee

    Choose coarse grounds to reduce bitterness and make straining easier.

  2. Step 2

    Mix coffee and water

    Combine about 1 part coffee with 4 parts water for concentrate, then adjust future batches to taste.

  3. Step 3

    Stir gently

    Make sure all grounds are wet without whipping air into the mixture.

  4. Step 4

    Steep slowly

    Cover and steep at room temperature or in the refrigerator for 12 to 18 hours.

  5. Step 5

    Strain once

    Pour through a fine strainer to remove most grounds.

  6. Step 6

    Filter again

    Run the liquid through a coffee filter or cheesecloth for a smoother drink.

  7. Step 7

    Dilute and store

    Mix concentrate with water or milk to taste and refrigerate the rest.

Practical Example

Example: You mix one cup of coarse coffee with four cups of water overnight, strain it in the morning, then dilute one part concentrate with one part milk.

Common Mistakes

  • Using finely ground coffee
  • Steeping too briefly
  • Forgetting to dilute concentrate
  • Using dirty containers
  • Squeezing filters too hard
  • Keeping cold brew too long

Troubleshooting

Cold brew tastes bitter

Use coarser grounds, shorten steeping, or avoid squeezing the filter.

Cold brew tastes weak

Use more coffee, steep longer, or dilute less.

There is grit in the cup

Filter a second time through paper or cheesecloth.

Flavor is flat

Use fresher coffee and adjust the ratio in the next batch.

FAQs
