Cold brew coffee is made by steeping coarsely ground coffee in cold or room-temperature water for an extended period, typically 12 to 24 hours. Unlike iced coffee (which is hot-brewed coffee poured over ice), cold brew is never exposed to heat. The result? A naturally smooth, low-acid concentrate that's rich in flavor and easy on the stomach.
If you've ever wondered what is cold brew coffee and why it tastes so different from your regular cup, the answer is simple: time replaces heat. Slow extraction pulls out the coffee's sweetness and body without the bitterness that comes from hot brewing.
Cold Brew vs Iced Coffee: What's the Difference?
This is one of the most common questions we get. Here's the short version:
- Cold brew is steeped in cold water for 12–24 hours. It's smooth, slightly sweet, and less acidic.
- Iced coffee is brewed hot and then chilled or poured over ice. It can taste sharper and more bitter.
If you're sensitive to acidity or prefer a mellower flavor, cold brew wins every time. It's also more concentrated, so a little goes a long way.
The Perfect Cold Brew Coffee Ratio
Getting the cold brew coffee ratio right is the single most important step. Use too little coffee and it'll taste watery. Use too much and it becomes overwhelmingly strong.
The sweet spot: 1:4 for concentrate (1 part coffee to 4 parts water) or 1:8 for ready-to-drink cold brew.
We recommend starting with the concentrate ratio you can always dilute it with water or milk to taste.
How to Make Cold Brew Coffee at Home
Here's a simple, foolproof cold brew coffee recipe you can make with equipment you already own.
What You'll Need
- Coarsely ground coffee (see our recommendation below)
- Cold or room-temperature filtered water
- A large jar, pitcher, or French press
- A fine mesh strainer or cheesecloth
Step-by-Step Instructions
- Grind your coffee coarsely. A coarse grind prevents over-extraction and keeps your cold brew smooth. Think sea salt texture not fine espresso powder.
- Combine coffee and water. Use a 1:4 ratio for concentrate. For example, 1 cup of ground coffee to 4 cups of water.
- Stir gently to make sure all the grounds are saturated.
- Cover and steep. Leave it in the fridge (or on the counter) for 12–24 hours. Longer steep = stronger flavor.
- Strain. Pour the mixture through a fine mesh strainer or cheesecloth into a clean jar. Discard the grounds.
- Serve and enjoy. Dilute with water or milk if using concentrate. Pour over ice and drink immediately, or store in the fridge for up to 2 weeks.
The Best Coffee for Cold Brew
Not all coffee is created equal when it comes to cold brew. You want a bean that's flavorful enough to shine through the slow extraction process, ideally something with chocolatey, nutty, or caramel notes that become even more pronounced when cold-brewed.
Our Cold Brew Coffee blend is specifically crafted for cold extraction. It's ground to the ideal coarseness and sourced for the kind of deep, smooth flavor that makes cold brew worth making at home.
If you want something with a little more intensity great for concentrate that you'll dilute, try our Cold Brew Coffee – Perfect Every Time. It's dialed in for consistency, so every batch comes out right.
For those who want maximum caffeine with full flavor, our Max Caf Blend is a high-caffeine option that holds up beautifully in cold brew.
Cold Brew Coffee Concentrate: How to Use It
If you brewed at a 1:4 ratio, you've made a cold brew coffee concentrate. Here's how to use it:
- Classic cold brew: Mix 1 part concentrate with 1 part water or milk over ice.
- Cold brew latte: Mix concentrate with oat milk or whole milk for a creamy, café-style drink.
- Cold brew tonic: Pour concentrate over tonic water with a slice of orange surprisingly refreshing.
- Baking: Use concentrate in brownies, tiramisu, or coffee ice cream for an intense coffee flavor.
Tips for the Best Cold Brew Every Time
- Use filtered water. Water quality directly affects flavor. Tap water with heavy chlorine can dull the taste.
- Don't rush the steep. 12 hours is the minimum; 18–20 hours is the sweet spot for most blends.
- Store it properly. Keep your cold brew in a sealed jar in the fridge. It stays fresh for up to 2 weeks.
- Experiment with ratios. Once you've nailed the basics, try adjusting the coffee-to-water ratio to match your taste.
