What Is Cold Brew Coffee?

Cold brew coffee is a method of brewing coffee using cold or room temperature water over an extended period, typically 12 to 24 hours. This slow extraction process results in a smooth, less acidic coffee concentrate that can be served cold or hot.

Unlike traditional hot brewing methods, cold brew doesn’t rely on heat to extract flavor from the coffee grounds. Instead, it uses time to slowly draw out the coffee’s oils, sugars, and caffeine, resulting in a unique flavor profile that many coffee lovers find irresistible.

The Cold Brew Process: How It’s Made

The cold brew process is surprisingly simple, but it requires patience:

  1. Coarsely ground coffee is combined with cold water in a container.
  2. The mixture is left to steep for 12-24 hours at room temperature or in the refrigerator.
  3. After steeping, the coffee grounds are filtered out, leaving behind a concentrated coffee liquid.
  4. This concentrate is then diluted with water or milk before serving.

The extended steeping time allows for a more thorough extraction of coffee flavors without the bitterness often associated with hot brewing methods.

Cold Brew vs. Iced Coffee: What’s the Difference?

While both cold brew and iced coffee are served chilled, they’re fundamentally different:

  • Iced Coffee: Regular hot-brewed coffee that’s cooled down and served over ice.
  • Cold Brew: Coffee that’s brewed using cold water from start to finish.

The key differences lie in their:

  • Brewing temperature
  • Brewing time
  • Flavor profile
  • Acidity levels
  • Caffeine content

Cold brew typically has a smoother, less acidic taste compared to iced coffee, and often contains more caffeine due to its higher coffee-to-water ratio and longer brewing time.

Benefits of Cold Brew Coffee

Cold brew coffee offers several advantages over traditional hot-brewed coffee:

  1. Lower Acidity: The cold brewing process results in coffee that’s up to 67% less acidic, making it easier on sensitive stomachs.
  2. Smoother Flavor: Without the bitter compounds extracted by hot water, cold brew has a naturally sweeter, smoother taste.
  3. Higher Caffeine Content: The concentrated nature of cold brew often means a higher caffeine kick per serving.
  4. Longer Shelf Life: Cold brew concentrate can last up to two weeks in the refrigerator without significant loss of flavor.
  5. Versatility: It can be served hot or cold and used as a base for various coffee drinks.
  6. Less Oxidation: The slow brewing process and lower temperatures result in less oxidation of coffee oils, preserving more of the coffee’s natural flavors.

How to Make Cold Brew Coffee at Home

Making cold brew coffee at home is easy and requires minimal equipment. Here’s a simple recipe:


  • 1 cup (100g) coarsely ground coffee
  • 4 cups (1 liter) cold filtered water


  1. Combine the ground coffee and water in a large jar or pitcher.
  2. Stir gently to ensure all grounds are saturated.
  3. Cover and let steep at room temperature for 12-24 hours.
  4. Strain the mixture through a fine-mesh sieve lined with cheesecloth or a coffee filter.
  5. Store the resulting concentrate in the refrigerator for up to 2 weeks.
  6. To serve, dilute the concentrate with water or milk to taste, typically using a 1:1 ratio.

Choosing the Best Beans for Cold Brew

While you can use any coffee beans for cold brew, certain characteristics work particularly well:

  • Roast Level: Medium to dark roasts often produce the best results, offering a rich, smooth flavor without overwhelming bitterness.
  • Origin: Single-origin coffee beans from regions like Colombia, Guatemala, or Ethiopia can provide unique flavor profiles.
  • Grind Size: A coarse grind is essential to prevent over-extraction and ensure easy filtering.

Cold Brew Concentrate: What It Is and How to Use It

Cold brew concentrate is the undiluted result of the cold brewing process.

It’s a versatile base for various coffee drinks:

  • Dilute with water or milk for traditional cold brew coffee
  • Add hot water for an Americano-style hot coffee
  • Use in cocktails or dessert recipes
  • Mix with flavored syrups for custom coffee drinks

The typical dilution ratio is 1:1 (concentrate to water), but you can adjust to your taste preferences.

  1. Cold Brew Maker: Specialized pitchers with built-in filters for easy brewing and straining.
  2. Large Mason Jars: Perfect for steeping and storing your cold brew.
