The Best Ways to Make Cold Brew Coffee
Your guide to smooth, low-acid cold brew - at home, with simple tools.
What Is Cold Brew & Why It Wins
Cold brew is made by steeping coarsely ground coffee beans in cold or room-temperature water for 12–24 hours, then straining out the grounds
This method extracts a smooth, less acidic cup with higher caffeine and richer flavor than iced coffee made with hot brew.
At-Home Cold Brew – Classic Method
What you need:
-
Coarse-ground beans (like sea salt in texture)
-
Filtered water
-
Mason jar or pitcher
-
Fine-mesh sieve, nut-milk bag, or French press
Steps:
-
Grind beans coarsely—aim for uniform size to prevent grit.
-
Ratio: Coffee to water can vary:
-
1:8 weight (e.g., 125 g coffee to 1 L water) for smooth concentrate
-
1:4 for a stronger concentrate
-
-
Steep: Cold room temps for 12–24 hrs, or fridge for ~24 hrs
-
Filter out grounds: Use sieve, French press, or cheesecloth
-
Dilute to taste: Mix 1:1 with water/milk or customize your ratio
-
Store in fridge: Keeps 7–14 days—refrigerated
Alternative Approaches
Flash Brew (Japanese-Style Iced Coffee)
Hot brew poured over ice to flash chill—retains brightness but tastes different from cold brew.
Slow Drip / Kyoto-Style
Water drips slowly through beans over hours. Requires special equipment but yields complex, refined flavors .
Expert Tips for a Perfect Brew
-
Uniform coarse grind prevents bitterness and grit
-
Use filtered water to highlight coffee’s flavor profile
-
Steep 12–24 hrs—too short = weak; too long (>24 hrs) = bitter
-
Chill with coffee ice cubes to avoid diluting flavor
Serving Suggestions
Classic: Pour over ice, dilute with water or creamer.
Upgrades:
-
Add a splash of cold milk or cream.
-
Infuse flavors during steeping—vanilla, cinnamon, or citrus peels
-
Make cocktails or dessert mixers—think cold brew martini or coffee pops
Why It’s Worth the Wait
-
Flavor payoff: Cold water extraction preserves complex oils and reduces bitterness
-
Higher caffeine by volume than hot-brewed equivalents
-
Low acidity is gentler on digestion
-
Make-ahead convenience: Prep once, enjoy all week.
