As temperatures rise and iced drinks take center stage, cold brew coffee once again claims its spot as the drink of the summer. But in 2025, cold brew isn’t just a trend—it’s a year-round staple with a devoted following. Smooth, low-acid, and deeply refreshing, cold brew is more than just chilled coffee. It’s a carefully crafted beverage with its own flavor identity and brewing method.

In this ultimate guide, we’ll explore how to make perfect cold brew at home, the best beans to use, gear that simplifies the process, and exciting new cold brew trends taking over cafés and kitchens this summer.
What Is Cold Brew Coffee?
Cold brew is a coffee brewing method that involves steeping coarsely ground coffee in cold or room-temperature water for an extended period, typically 12 to 24 hours. Unlike iced coffee, which is brewed hot and then cooled, cold brew is never heated—resulting in a smoother, sweeter, and less acidic profile.
Its mellow flavor and subtle chocolatey notes make it ideal for warm weather. It’s also highly versatile—you can serve it black, with milk, sweetened, or even infused with flavors like vanilla or citrus.
Why Cold Brew Is Trending in 2025
This year, cold brew is being redefined by innovation and wellness-conscious consumers. From nitrogen-infused options to oat milk cold brew lattes, the drink is finding its way into cans, cocktails, and even mocktail menus.
One key reason for its continued popularity is its low acidity, making it gentler on the stomach. Additionally, its bold caffeine kick, combined with a clean finish, appeals to both casual drinkers and serious coffee enthusiasts.
With many people investing in better home brewing gear, making café-quality cold brew at home has become easier than ever.
How Cold Brew Differs from Iced Coffee
While both drinks are served cold, they couldn’t be more different in taste and preparation. Iced coffee is brewed hot and poured over ice, which can dilute its flavor and increase bitterness. Cold brew, by contrast, is brewed slowly in cold water, extracting fewer bitter compounds and resulting in a smoother, rounder cup.
Cold brew is often more concentrated and can be diluted with water or milk to your preferred strength. Its longer shelf life—up to two weeks when stored properly—makes it a convenient option for batch brewing.
Best Coffee Beans for Cold Brew in 2025
While you can make cold brew with any coffee, certain beans shine brighter in cold extraction methods. In 2025, single-origin beans and naturally processed coffees are leading the cold brew scene.
What to Look For
Aim for medium to dark roasts for a richer, chocolatey profile. Light roasts can also work but often produce brighter, tea-like notes that some may find too subtle. Beans from Latin America, such as Brazilian or Colombian varieties, tend to produce smooth, nutty brews. African beans like Ethiopian or Kenyan origins deliver fruity, floral cold brews with layered complexity.

Rich, full-bodied, and balanced with cocoa and red fruit undertones. - Brazil Cerrado – Natural Process

How to Make Cold Brew Coffee at Home
Making cold brew at home is surprisingly easy. All you need are good beans, water, and a container. The result? A concentrated brew that can be enjoyed in a variety of ways.
Ingredients
- 1 cup coarsely ground coffee
- 4 cups cold or room-temperature filtered water
This 1:4 ratio produces a strong concentrate. Adjust based on how you like your brew.
Equipment You’ll Need
- A large mason jar, French press, or cold brew maker
- A fine-mesh sieve, cheesecloth, or coffee filter
- Coffee grinder (preferably burr)
- Refrigerator space for steeping
Step-by-Step Brewing Method
- Grind the Coffee

Add coffee grounds to your jar or brewer, then slowly pour in the water, ensuring all grounds are saturated. Stir gently to mix. - Steep
Cover the container and let it sit at room temperature or in the fridge for 12 to 24 hours. Longer steeping results in stronger flavor. - Strain
Use a cheesecloth or coffee filter to strain the grounds from the liquid. You may need to strain twice for a clean finish. - Store and Serve
Transfer your cold brew to a clean container. Store in the fridge for up to two weeks. Serve over ice, diluted to taste, or mixed with milk or sweetener.

Common Mistakes to Avoid
Using Fine Grounds
Fine grinds can over-extract and lead to a bitter or muddy brew. Stick to a coarse grind for clarity and smoothness.
Not Filtering Properly
Inadequate filtration can result in sludge at the bottom of your cup. Take the time to strain thoroughly.
Steeping Too Long or Too Short
Brewing under 12 hours may yield a weak brew, while over 24 hours can create bitterness. Find your sweet spot based on taste.
