How to Make Cold Brew Without Special Equipment
Cold brew coffee has a reputation for requiring special equipment — dedicated cold brew makers, special filters, expensive systems. The truth is that all you need is a jar, a coffee filter or cheesecloth, and patience. Here's how to make excellent cold brew at home without any special equipment.
What Is Cold Brew and Why Does It Taste Different?
Cold brew is made by steeping coarsely ground coffee in cold or room-temperature water for 12–24 hours, then filtering out the grounds. The cold extraction process produces coffee that's naturally sweeter, less acidic, and less bitter than hot-brewed coffee — because the compounds that create acidity and bitterness require heat to extract. The result is a smooth, mellow concentrate that's delicious over ice.
What You Need
A large jar or container (32 oz or larger), coarsely ground coffee, cold or room-temperature water, and a fine mesh strainer or coffee filter for filtering. That's it. No special equipment required. A kitchen scale is helpful for consistency but not essential.
The Ratio: 1:4 for Concentrate
For cold brew concentrate (which you dilute before drinking), use a 1:4 ratio: 1 part coffee to 4 parts water by weight. For a 32 oz jar, use about 100g of coffee and 400g of water. This produces a concentrate you dilute 1:1 with water or milk when serving. For ready-to-drink cold brew, use a 1:8 ratio.
The Process: Simple and Hands-Off
Add coarsely ground coffee to your jar. Pour cold or room-temperature water over the grounds and stir gently to ensure all grounds are saturated. Cover the jar and refrigerate for 12–24 hours — 12 hours for a lighter, more delicate flavor; 24 hours for a stronger, more intense concentrate. The longer steep produces more caffeine and more body.
Filtering: The Only Tricky Part
After steeping, filter the concentrate through a fine mesh strainer lined with a paper coffee filter or cheesecloth. Pour slowly and let gravity do the work — don't press or squeeze, which can introduce bitterness. The filtering takes 5–10 minutes. The result is a clear, smooth concentrate that keeps in the refrigerator for up to 2 weeks.
Serving: Over Ice in the Right Glass
Serve cold brew concentrate over ice, diluted 1:1 with water or milk. A large clear glass shows off the beautiful amber color of cold brew and lets you see the layers when you add milk. A ribbed tumbler with a lid and straw makes it portable for on-the-go enjoyment.

Experiment with Steep Time and Ratio
Cold brew is forgiving and highly customizable. If your first batch is too strong, dilute more or reduce the steep time. Too weak? Steep longer or use more coffee. Once you find your preferred ratio and steep time, cold brew becomes one of the most consistent and effortless coffee preparations you can make at home.
