How to Make Cold Brew Coffee at Home (Simple Method + Ratio)

Cold brew coffee is smooth, naturally sweet, and far less acidic than hot coffee — and it's one of the easiest ways to make great coffee at home. No fancy equipment, no barista skills. Just coffee, water, and a little patience. Here's exactly how to do it.

What is cold brew (and why it's different)

Cold brew is coffee steeped in cold or room-temperature water for 12–24 hours, rather than brewed with heat. The slow, cold extraction pulls out sweetness and body while leaving behind much of the bitterness and acidity — which is why cold brew tastes so mellow and is easy on the stomach.

What you'll need

  • Coarsely ground coffee (a cold-brew or medium-dark blend works best)
  • Cold, filtered water
  • A jar or pitcher
  • A fine strainer, nut-milk bag, or a cold-brew maker

The cold brew ratio

Start with a 1:8 ratio — 1 part coffee to 8 parts water by weight — for a strong concentrate you can dilute to taste. For example: about 100g of coarse-ground coffee to 800g (about 4 cups) of water.

Step-by-step

  1. Add coarse-ground coffee to your jar.
  2. Pour in the cold water and stir gently so all the grounds are saturated.
  3. Cover and steep 12–24 hours at room temperature or in the fridge. Longer steeping means stronger coffee.
  4. Strain out the grounds through a fine filter or nut-milk bag.
  5. Serve over ice. Dilute the concentrate 1:1 with water or milk to taste.

The best coffee for cold brew

A coarse grind and a smooth, low-acid roast make the best cold brew. Our Cold Brew Coffee blend is built specifically for it — smooth, chocolatey, and low in acidity. Prefer a single origin? A medium-dark like Sumatra or Bali Blue also shines cold. Browse the full coffee collection to pick your beans.

Tips for better cold brew

  • Grind coarse — fine grounds make it cloudy and over-extracted.
  • Store the concentrate in the fridge for up to 2 weeks.
  • Add a splash of vanilla, or shake over ice for a nitro-style texture.
