Learn how to make a smooth, bold cold brew at home using Stone Street Coffee's Cold Brew Swiss Water Decaf. This step-by-step guide covers grind, ratio, steep time, and common mistakes.
Quick answer
Brew a smooth, bold cold brew at home using Stone Street Coffee's Cold Brew Swiss Water Decaf with a coarse grind, a 1:8 coffee-to-water ratio, and a 12- to 18-hour steep in the fridge.
Why Swiss Water Process matters for cold brew
Swiss Water Process removes caffeine using only water and osmosis, leaving the bean's natural oils and flavor compounds intact. That means your cold brew retains a balanced, bold taste with slight sweetness and low acidity—without the jolt.
Because the beans are already decaffeinated, you can steep longer without worrying about over-extracting caffeine. The key is to focus on flavor extraction instead.
How to brew cold brew with Swiss Water Decaf
- Choose the right grind: Grind your Cold Brew Swiss Water Decaf beans to a coarse consistency—similar to breadcrumbs. A fine grind will make the cold brew bitter and cloudy. If you don't have a grinder, select the 'coarse grind' option when ordering.
- Measure your coffee and water: Use a 1:8 ratio: 1 cup (about 85 grams) of ground coffee to 8 cups (64 ounces) of cold, filtered water. This produces a concentrate you can dilute later. Too much coffee can over-extract and taste harsh; too little yields weak concentrate.
- Combine and stir: Add the coffee grounds to a large jar or pitcher, pour in the water, and stir gently until all grounds are saturated. Avoid vigorous stirring that incorporates excess air. Make sure no dry clumps remain—they won't extract evenly.
- Steep in the refrigerator: Cover the container and place it in the fridge for 12 to 18 hours. Longer steeps (up to 24 hours) can add bitterness, especially with decaf beans that are more delicate. Taste at 12 hours; if it's strong enough, strain it. Don't let it go past 18 hours.
- Strain and store: Pour the mixture through a fine-mesh sieve lined with a coffee filter or a nut milk bag into a clean container. Press or squeeze gently to extract all liquid. Store the concentrate in the fridge for up to two weeks. A paper filter removes fine silt for a cleaner cup; a mesh strainer alone may leave sediment.
- Serve and enjoy: Pour the concentrate over ice and dilute with equal parts water, milk, or your favorite milk alternative. Adjust to taste—some prefer a stronger 1:1 ratio, others a lighter 1:2. Start with a 1:1 dilution and tweak from there. The concentrate is very strong on its own.
