Learn how to make cold brew coffee at home with our step-by-step guide. Discover the best beans, grind size, and brewing tips for smooth, rich cold brew.

Cold brew coffee is a summer staple, but you don't need a café to enjoy it. With a little patience and the right beans, you can craft a smooth, low-acid concentrate right in your kitchen. This guide walks you through the entire process, from choosing beans to serving suggestions.

Whether you're a cold brew connoisseur or a curious beginner, these steps will help you brew a batch that rivals your favorite coffee shop. We'll cover the essential equipment, the ideal coffee-to-water ratio, and tips for customizing your brew to taste.

Why Make Cold Brew at Home?

Cold brew is different from iced coffee: it's steeped in cold water for 12-24 hours, resulting in a concentrate that's less acidic and naturally sweeter. Making it at home lets you control the strength and flavor, and it's more economical than buying a bottle every day.

Plus, you can experiment with different single-origin beans to find your favorite. For a fruity, vibrant cup, try a light roast like the Honduras El Puente Natural. If you prefer a chocolatey, full-bodied brew, a blend like Holler Mountain works beautifully.

  • Cold brew is less acidic and smoother on the stomach.
  • Home brewing allows total control over strength and flavor.
  • Experiment with different beans to discover new taste profiles.

What You'll Need

The beauty of cold brew is that you don't need fancy equipment. A large jar or pitcher, a fine-mesh strainer, and a coffee filter or cheesecloth are enough. For the best results, use a coarse grind—think breadcrumb texture—to avoid over-extraction and bitterness.

If you're looking to invest in a dedicated brewer, the Bonavita Connoisseur (8 Cup) is a versatile option for hot coffee, but for cold brew, a simple mason jar works perfectly. Don't forget to stock up on quality beans; a 12-ounce bag of your favorite roast is ideal for a batch.

  • Use a coarse grind for a clean, smooth cup.
  • A mason jar or French press works well for steeping.
  • Fresh, whole beans ground just before brewing yield the best flavor.

Step-by-Step Cold Brew Recipe

Start with a 1:8 ratio of coffee to water for a concentrate. For a milder brew, use 1:10. Combine 1 cup of coarsely ground coffee with 8 cups of cold, filtered water in your container. Stir gently to ensure all grounds are saturated.

Cover and let it steep at room temperature or in the fridge for 12-18 hours. Longer steeping increases strength and boldness. After steeping, strain the mixture through a fine-mesh sieve lined with a coffee filter or a nut milk bag. The result is a smooth concentrate that can be diluted with water or milk.

Store the concentrate in the fridge for up to two weeks. To serve, fill a glass with ice, add equal parts cold brew and water or milk, and enjoy. For a ready-to-drink option, Stumptown's Horchata Cold Brew with Oatly offers a spiced, creamy twist—perfect for when you're short on time.

  • Steep for 12-18 hours for optimal flavor extraction.
  • Filter twice if you prefer a crystal-clear brew.
  • Dilute with water or milk to taste; adjust ratio to your preference.

Choosing the Right Beans

The beans you choose dramatically affect your cold brew. Light roasts with fruity notes, like the Indonesia Bies Penantan, produce a vibrant, tea-like brew. Darker roasts yield a richer, more chocolatey cup. For a balanced option, a blend like Holler Mountain offers notes of hazelnut and dark chocolate.

If you're new to cold brew, start with a medium roast to get a feel for the process. Experiment with different origins to find your favorite. Remember, the grind size is more crucial than the roast level—keep it coarse to avoid bitterness.

  • Light roasts: bright, fruity, and tea-like.
  • Dark roasts: rich, chocolatey, and full-bodied.
  • Blends offer a balanced, crowd-pleasing flavor.

Tips for Perfect Cold Brew Every Time

Use filtered water for the cleanest taste. Tap water can introduce off-flavors. Keep your brewing vessel clean and free of residual oils from previous batches. And always measure your coffee and water by weight for consistency.

If you're brewing a large batch, consider a cold brew maker with a built-in filter to simplify the process. While the Kalita Wave Filters (100 Pack) are designed for pour-over, they can double as a fine filter for cold brew if you're in a pinch. Just be sure to rinse them first to avoid paper taste.

  • Use filtered water for best flavor.
  • Measure coffee and water by weight for accuracy.
  • Rinse paper filters before use to avoid paper taste.

Making cold brew at home is simple, rewarding, and customizable. With the right beans and a little patience, you'll have a smooth, delicious concentrate that beats any store-bought version. So grab your favorite Stumptown coffee, try this recipe, and enjoy the perfect iced coffee all summer long.
