The Basics of Cold Brew
Cold brew coffee is a type of coffee that is typically made using a brewing process that involves steeping coarse coffee grounds in cold water for an extended period – usually between 12 and 24 hours.
To serve, pour the cold brew concentrate over ice and add water to taste.
For a creamier option, you can also add milk, cream, or sweeteners as desired.
Here is a recipe for making cold brew coffee:

kcalIngredients
1 cup coarsely ground coffee beans
4 cups cold water
1 large jar or pitcher
Cheesecloth or fine-mesh strainer
Directions
- Pour the coffee grounds into the jar or pitcher.
- Slowly pour the cold water over the coffee grounds, making sure that all of the grounds are fully saturated.
- Cover the jar or pitcher and let it sit at room temperature for 12-24 hours.
- Once the coffee has steeped, strain it through a cheesecloth or fine-mesh strainer.
- Store the cold brew coffee in the fridge until ready to serve.
Notes
- Use high-quality, freshly roasted coffee beans for the best results.
- Experiment with different bean varieties and roast levels to find your preferred flavor profile.
- Dilute the cold brew coffee with water or milk to taste, as it can be quite strong on its own.
- Mix cold brew coffee with flavored syrups or spices to create unique and delicious drinks.
Brewing Ratios & Measurements
When making cold brew coffee, getting the ratio of coffee to water just right is key to achieving that smooth, rich flavor.
A good starting point is a 1:4 ratio for a strong concentrate (1 cup of coarsely ground coffee to 4 cups of cold water).
If you prefer a ready-to-drink brew, go for a 1:8 ratio.
- Cold Brew Concentrate Ratio:
- 1 cup (85g) coarsely ground coffee
- 4 cups (950ml) cold filtered water
- Ready-to-Drink Ratio:
- 1 cup (85g) coarsely ground coffee
- 8 cups (1.9L) cold filtered water
You can always dilute a concentrate with water, milk, or a milk alternative before serving.
Cold brew is very forgiving, so switch it up and experiment to find what suits your taste buds.
Steeping Time Recommendations
Steeping time plays a crucial role in how your cold brew turns out.
The general recommendation is 12 to 24 hours, depending on how strong and bold you want your brew to be.
- 12 Hours: Light and mellow
- 16 Hours: Smooth, balanced
- 24 Hours: Bold, rich, more robust
Steeping longer allows more of the coffee’s oils and flavors to extract, but going past 24 hours might introduce bitterness or over-extraction.
Always refrigerate your brew while steeping to prevent any unwanted fermentation or bacterial growth.
💡Pro Tip: If you want to enjoy your cold brew in the morning, set it up the night before and let it steep overnight.
Filtering Methods
Once your cold brew is steeped, it’s time to filter it. The goal is to remove the gritty coffee grounds for a smooth, clean sip. Here are a few options:
- Fine Mesh Sieve: Line with a paper towel or cheesecloth to catch finer particles.
- Cheesecloth: Double-layer it and strain into another container.
- French Press: Press down the plunger slowly, then pour.
- Cold Brew Maker: Devices like the Hario Mizudashi make straining a breeze.
No matter what you use, strain at least once—twice if you want an ultra-smooth finish. Avoid using a regular coffee filter alone, as it may clog or take forever to drain.
Storage Guidelines
Cold brew concentrate is great for batch-making and storing.
After straining, transfer it into an airtight glass container like a mason jar or bottle. It will stay fresh in the fridge for up to 7–10 days.
- Cold Brew Concentrate: Store in fridge for 7–10 days
- Diluted Cold Brew: Best consumed within 3–4 days
Label the container with the brew date so you don’t forget when you made it.
Avoid plastic containers if possible, as they may absorb odors and alter the flavor.
If you want to take things a step further, freeze cold brew in ice cube trays. These coffee cubes are perfect for iced drinks and prevent your cold brew from watering down.
Serving Suggestions
Once you have your cold brew concentrate, the fun begins! Here are some delicious ways to serve it:
- Classic Iced Cold Brew: Mix 1 part concentrate with 1 part water over ice.
- Cold Brew Latte: Mix 1 part concentrate with 1 part milk or plant-based milk.
- Sweetened Cold Brew: Add simple syrup, maple syrup, or flavored syrup.
- Cold Brew Tonic: Add cold brew over tonic water with a slice of orange for a refreshing twist.
- Spiced Cold Brew: Stir in a dash of cinnamon or nutmeg for a cozy, aromatic sip.
💡Bonus Tip: Blend cold brew with ice and milk for a quick and easy homemade coffee frappe!
