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:
- Coarsely ground coffee is combined with cold water in a container.
- The mixture is left to steep for 12-24 hours at room temperature or in the refrigerator.
- After steeping, the coffee grounds are filtered out, leaving behind a concentrated coffee liquid.
- 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:
- Lower Acidity: The cold brewing process results in coffee that’s up to 67% less acidic, making it easier on sensitive stomachs.
- Smoother Flavor: Without the bitter compounds extracted by hot water, cold brew has a naturally sweeter, smoother taste.
- Higher Caffeine Content: The concentrated nature of cold brew often means a higher caffeine kick per serving.
- Longer Shelf Life: Cold brew concentrate can last up to two weeks in the refrigerator without significant loss of flavor.
- Versatility: It can be served hot or cold and used as a base for various coffee drinks.
- Less Oxidation: The slow brewing process and lower temperatures result in less oxidation of coffee oils, preserving more of the coffee’s natural flavors.

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.
