Cold Brew Coffee Recipe

Cold brew coffee is smooth, bold, and low in acid. You make it by steeping coarsely ground beans in cold water for hours, then straining for a clean, refreshing drink. This method pulls out sweet, chocolatey notes without the bitterness you get from hot brewing. It’s mostly hands-off, perfect for busy mornings, and easy to scale for a week of sips. I’ll show you a simple ratio, clear steps, and smart tips so you can brew like a pro at home—no fancy gear needed.

Why Make Cold Brew Coffee

Cold brew coffee gives you a café-level drink with almost no effort. The long, cold steep makes a smooth cup with less bite, so it tastes great black or with milk. It’s a budget-friendly way to enjoy coffee shop flavor at home, and you can customize it to your taste—strong or mild, sweet or unsweetened, creamy or bright. Because it’s a concentrate, one batch turns into many drinks, which saves time all week.

This recipe shines in warm weather when you crave something cool and refreshing. Pour it over ice for a crisp afternoon pick-me-up, or mix it with milk for a silky iced latte. It also works in cooler months: just dilute the concentrate with hot water for a fast, gentle hot coffee that stays smooth. Make a jar on Sunday, and you’ll have ready-to-sip coffee through Friday. It stores well, tastes clean, and makes mornings simple. Once you start, you’ll want a batch in your fridge all the time.

Ingredients and Substitutions

What You’ll Need for This Recipe

• Coarsely ground coffee: 1 cup (about 85 g). Choose a medium to dark roast for a chocolatey, smooth profile.
• Cold, filtered water: 4 cups (960 ml) for a strong concentrate. Dilute 1:1 with water or milk to serve.
• Ice, for serving.
• Optional add-ins: milk or cream (dairy or non-dairy), simple syrup or maple syrup, vanilla extract, cinnamon stick, orange peel, or a pinch of sea salt.

Notes:

• Water quality matters. Filtered water gives a cleaner taste.
• If using whole beans, grind them coarsely—think raw sugar or breadcrumbs.
• Tools: 1-quart jar or pitcher, spoon, fine-mesh strainer plus coffee filter or a clean cloth.

Smart Swaps for Dietary Needs

• Dairy-free: Use almond, oat, soy, or coconut milk.
• Low sugar: Skip syrup and sweeten with stevia or enjoy it black.
• Keto/low-carb: Use heavy cream or unsweetened nut milk and a keto-friendly sweetener.
• Low-acid: Choose a low-acid bean and stick to a 12–16 hour steep for a mellow cup.

Smart Variation (Optional)

• Vanilla Almond: Add 1 teaspoon vanilla extract before steeping and finish with almond milk.
• Citrus Spice: Add a strip of orange peel and 1 small cinnamon stick to the jar.
• Mocha: Stir in 1–2 teaspoons cocoa powder with the grounds; sweeten to taste after straining.

How to Make Cold Brew Coffee

Step-by-Step Cooking Instructions

Step 1: Measure 1 cup (about 85 g) coarsely ground coffee and 4 cups (960 ml) cold, filtered water.

Step 2: Add the grounds to a clean 1‑quart jar or pitcher. If grinding at home, use the coarsest setting.

Step 3: Pour in the water. Stir slowly to wet all the grounds. Make sure no dry pockets remain.

Step 4: Cover the jar. Give it a gentle shake or stir after 5 minutes to ensure full saturation.

Step 5: Let the mixture rest on the counter for 10 minutes to start extraction, then move it to the fridge.

Step 6: Refrigerate to steep at 35–40°F (2–4°C) for 12–24 hours. For smooth balance, aim for 16–18 hours.

Step 7: Strain through a fine-mesh sieve lined with a coffee filter or clean cloth. For an extra-clear brew, strain twice. To serve, dilute concentrate 1:1 with cold water or milk, add ice, and sweeten if you like.

Tips for Texture, Timing & Tools

• Grind size: Keep it coarse to avoid bitterness and sludge.
• Ratio: 1:4 (coffee:water) makes a strong concentrate. For ready-to-drink strength, use 1:8 or dilute concentrate 1:1.
• Steep time: 12–16 hours = bright and smooth; 18–24 hours = bolder and stronger. If it tastes harsh, shorten the time.
• Filter well: A second strain makes a cleaner, longer-lasting brew.
• No scale? Use 1 cup grounds to 4 cups water; adjust strength after straining.
• Flavor control: Add sweeteners and milk after straining, not before.

Storage & Reheating

How to Store It Right

• Store concentrate in a sealed jar in the fridge for up to 1 week.
• Once diluted, use within 3–4 days for best flavor.
• Freeze leftover concentrate in ice cube trays. Drop cubes into milk or water for quick coffee without watering it down.

Reheating Without Losing Flavor

• For a hot cup, mix concentrate with hot water (about 1:1) instead of boiling the coffee. This keeps it smooth and low in bitterness.
• If microwaving, warm the diluted coffee in short 20–30 second bursts; do not let it boil.
• Heat milk or foam it separately for a cozy latte-style drink.

A Dish Worth Making Again and Again

This is a low-effort, high-reward staple. One simple batch gives you days of café-quality coffee, just the way you like it.

FAQs

What’s the best coffee-to-water ratio for cold brew?

Use 1:4 (coffee:water) for a concentrate you can dilute 1:1. For ready-to-drink strength without diluting, use 1:8.

How long should I steep cold brew?

Steep 12–24 hours in the fridge. Most people love 16–18 hours for a smooth, balanced cup.

Can I use pre-ground coffee?

Yes, if it’s coarse. If your pre-ground coffee is fine, reduce the steep time to prevent bitterness and strain through a thicker filter.

What’s the difference between iced coffee and cold brew?

Iced coffee is hot coffee cooled over ice, often more acidic. Cold brew steeps in cold water, which makes it smoother and less acidic.

Final Thoughts

Cold brew coffee is simple, flexible, and reliable. With the right grind, a good ratio, and an overnight steep, you’ll have a smooth concentrate ready for any mood—iced, hot, sweet, or creamy. Make it once, and your mornings get easier all week.
