If you love smooth, refreshing coffee but want to avoid spending money at a café every day, learning how to make cold brew coffee at home is a great place to start.
Cold brew is surprisingly easy to prepare. You don’t need an expensive coffee machine or complicated equipment. With freshly ground coffee, cold or room-temperature water, a jar, and a little patience, you can make delicious homemade cold brew in your own kitchen.
In this beginner-friendly guide, we’ll show you exactly how to make cold brew coffee at home, including the coffee-to-water ratio, brewing time, filtering method, and common mistakes to avoid.
What Is Cold Brew Coffee?
Cold brew coffee is coffee made by steeping coarsely ground coffee beans in water for several hours instead of brewing the coffee with hot water.
Unlike traditional iced coffee, which is normally brewed hot and then cooled over ice, cold brew is extracted slowly. This produces a smooth and refreshing drink that many people enjoy over ice or with milk.

What You Need to Make Cold Brew Coffee
You only need a few basic ingredients and tools.
Ingredients
- 1 cup coarsely ground coffee
- 4 cups filtered water
- Ice, for serving
- Milk or cream, optional
- Sweetener or syrup, optional
Equipment
- Large glass jar or pitcher
- Coffee grinder, if using whole beans
- Fine-mesh strainer
- Cheesecloth or coffee filter
- Spoon
If you already have a coffee grinder at home, grinding your beans just before brewing can help you get a fresher flavor.
If you’re new to using a grinder, our beginner’s guide to using a coffee and spice grinder explains the basic process step by step.
The Best Coffee-to-Water Ratio for Cold Brew
For beginners, a 1:4 coffee-to-water ratio is a simple starting point.
That means:
1 cup of coarsely ground coffee + 4 cups of water
This creates a fairly concentrated cold brew that you can dilute with water or milk when serving.
If you prefer a lighter drink, you can experiment with a weaker ratio. The important thing is to choose one ratio, taste the result, and adjust it to your preference.
How to Make Cold Brew Coffee at Home
Follow these simple steps if you’re making cold brew for the first time.
Step 1: Grind the Coffee Beans
Start with whole coffee beans if possible and grind them coarsely.
The grounds should look similar to coarse sea salt. Avoid using a very fine grind because it can make filtering more difficult and may produce a muddy or bitter drink.
If you don’t have a grinder, you can also buy coffee that is already ground for cold brew.
For more information about choosing the right grind size and preparing fresh coffee, see our complete guide to brewing coffee at home.
Step 2: Add Coffee and Water
Place the coarsely ground coffee into a clean glass jar or pitcher.
Add the water slowly and make sure all of the coffee grounds become wet.
Give the mixture a gentle stir with a spoon.
Step 3: Let the Coffee Steep
Cover the container and leave it at room temperature or in the refrigerator while it steeps.
A good starting point is around 12 to 18 hours.
The exact brewing time depends on the coffee beans, grind size, water, and your preferred flavor.
If your cold brew tastes too strong or bitter, try reducing the brewing time next time.
Step 4: Filter the Cold Brew
After steeping, it’s time to separate the coffee grounds from the liquid.
Place a fine-mesh strainer over another container and line it with a coffee filter or cheesecloth.
Slowly pour the mixture through the filter.
Don’t rush this step. Cold brew can take a little time to filter, especially when you’re making a concentrated batch.
Step 5: Dilute and Serve
Your filtered coffee may be quite strong, depending on the ratio you used.
Fill a glass with ice and pour in some cold brew.
Then add water or milk according to your taste.
You can also add a little simple syrup, vanilla syrup, or another sweetener if you prefer sweeter coffee.

That’s it—you’ve made homemade cold brew coffee.
How to Make Cold Brew Less Bitter
If your cold brew tastes bitter, there are several things you can change.
Use a Coarser Grind
Very fine coffee grounds can lead to over-extraction and make filtering harder.
Try using a coarse grind instead.
Don’t Brew for Too Long
Longer brewing doesn’t always mean better coffee.
If your cold brew tastes harsh or overly bitter, reduce the steeping time on your next batch.
Use Good-Quality Water
Coffee is mostly water, so the water you use can affect the final taste.
Filtered water is a simple option for making better-tasting cold brew at home.
Don’t Use Extremely Dark Roasts Automatically
Dark-roasted beans can produce a stronger, more intense flavor.
If you prefer a smoother and lighter cold brew, try a medium roast and compare the result.
How Long Does Homemade Cold Brew Last?
Store your filtered cold brew in a clean, sealed container in the refrigerator.
For the best flavor, it’s a good idea to drink it within several days rather than keeping it for a long period.
Always check the smell and appearance before drinking, especially if the coffee has been stored for an extended time.
Cold Brew vs. Iced Coffee: What’s the Difference?
Cold brew and iced coffee are not exactly the same.
Cold brew is made by steeping coffee grounds in cold or room-temperature water for many hours.
Iced coffee is usually brewed with hot water and then cooled or poured over ice.
The preparation method changes the flavor, so you may prefer one depending on your taste.
If you want something quick, iced coffee is usually easier. If you want to prepare coffee ahead of time, cold brew can be very convenient.

Common Cold Brew Mistakes Beginners Should Avoid
When you’re learning how to make cold brew, a few common mistakes can affect the result.
Using a Fine Coffee Grind
Fine grounds can make the coffee difficult to filter and may produce an unpleasant texture.
Using Too Much Coffee
More coffee doesn’t automatically make better cold brew. Start with a measured ratio and adjust it gradually.
Brewing Without Measuring
If you simply guess the amount of coffee and water each time, your results can be inconsistent.
Using a measuring cup or kitchen scale can help you repeat a recipe you like.
Filtering Too Quickly
Give the coffee time to pass through the filter naturally. Pressing or squeezing the grounds aggressively can affect the final drink.
Drinking It Without Diluting
Depending on your recipe, homemade cold brew can be concentrated.
If it tastes too strong, add water or milk before deciding that the recipe didn’t work.

Can You Make Cold Brew Without a Coffee Maker?
Yes.
One of the biggest advantages of cold brew is that you don’t need a traditional coffee machine.
A clean jar, coffee grounds, water, and a suitable filter are enough to get started.
However, if you make coffee regularly, learning how to use a coffee machine can also help you explore other brewing methods at home.
If you’re thinking about buying a machine, our guide to choosing the right coffee maker for your home explains the differences between common types.
Final Thoughts
Learning how to make cold brew coffee at home doesn’t have to be complicated.
Start with coarse coffee grounds, use a consistent coffee-to-water ratio, allow enough time for the coffee to steep, and filter it carefully. Once you’ve made your first batch, you can experiment with different beans, ratios, brewing times, and serving styles.
The key for beginners is not to worry about making the perfect cold brew on the first attempt. Start with a simple recipe, taste the result, and make small adjustments until you find the flavor you enjoy.
If you’re building a better home coffee setup, choosing the right coffee grinder, coffee maker, and drinkware can also make your daily coffee routine easier and more enjoyable.
