Making cold brew at home feels almost too easy once you have done it once. There is no machine to learn, no timing to nail, no hot water to burn yourself on. You stir coffee and water together, walk away for a day, and come back to smooth, sweet, ready-to-drink coffee. If you can fill a jar, you can make cold brew.
This is our complete, beginner-friendly walkthrough on how to make cold brew coffee at home — the exact grind, ratio, and steep time, plus the small tips that make your first batch taste great. Let's brew.
To make cold brew: combine 1 cup of coarsely ground coffee with 4 cups (1 quart) of cold water, stir, cover, and refrigerate for 12–24 hours. Strain out the grounds, then serve over ice. That's a 1:4 concentrate you can dilute, or use 1:8 for ready-to-drink cold brew.
What You'll Need
- Coarsely ground coffee — about the texture of raw sugar or coarse sea salt
- Cold or room-temperature water — filtered tastes best
- A large jar or pitcher — a half-gallon mason jar is perfect
- A strainer — a fine-mesh sieve, a nut-milk bag, a paper coffee filter, or a built-in filter
That is genuinely it. You can use a mason jar you already own. If you make cold brew regularly, a dedicated maker with a built-in filter saves you the straining step — our beginner pick is below.
Step 1: Grind Your Coffee Coarse
This is the one step worth getting right. Cold brew steeps for many hours, so a fine grind will over-extract and give you a muddy, bitter, gritty cup. You want a coarse grind, roughly the texture of raw sugar or coarse sea salt. If you buy pre-ground, ask for a coarse or “cold brew / French press” grind. New to grind sizes? Our guide to coffee grind sizes shows exactly what to look for.
Pre-ground supermarket coffee is usually ground for drip machines — much too fine for cold brew. It will work in a pinch, but expect a siltier cup. A coarse grind makes a noticeable difference in smoothness.
Step 2: Measure Your Coffee and Water
Cold brew uses a simple ratio — parts coffee to parts water. Two easy starting points:
- 1:8 for ready-to-drink cold brew — for example, 1 cup grounds to 8 cups water. Pour straight over ice.
- 1:4 for concentrate — for example, 1 cup grounds to 4 cups water. Stronger; dilute with water or milk before drinking, and it keeps longer.
If you are not sure, start with a 1:4 concentrate — it is flexible. You can always add water to taste. For more on dialing this in, see Cold Brew Ratio: The Simple Formula for Beginners.
Step 3: Combine and Stir
Add your grounds to the jar, then pour in the water. Give it a gentle stir to make sure all the grounds are wet — dry clumps floating on top will not extract evenly. Do not worry about being precise or fancy here; a quick stir with a spoon is all it takes.
Step 4: Steep for 12–24 Hours
Cover the jar and let it steep. You have two options:
- In the fridge: steep the whole 12–24 hours cold. This is the easiest, most foolproof method.
- On the counter: steep at room temperature for up to 12–14 hours, then move it to the fridge. Room temperature extracts a little faster.
Around 16 hours is a reliable sweet spot for most people. Twelve hours gives a lighter, brighter brew; closer to 24 gives a bolder, richer one. Try not to push much past 24 hours — that is when flavors can turn woody and over-extracted.
Step 5: Strain Out the Grounds
Once it has steeped, separate the coffee from the grounds. If you used a dedicated maker, just lift out the filter. With a jar, pour the brew through a fine-mesh sieve. For an extra-clean cup, strain a second time through a paper coffee filter to catch fine sediment.
Do not press or squeeze the grounds to get every last drop — that pushes bitter compounds into your brew. Let it drain naturally for the smoothest result.
Step 6: Serve and Store
Pour your cold brew over a glass of ice. If you made concentrate, dilute it first — start with equal parts concentrate and water (or milk) and adjust to taste. Add a splash of cream, a little simple syrup, or a pinch of salt if you like.
Store the rest in a sealed container in the fridge. Ready-to-drink cold brew stays good for about 7–10 days; concentrate keeps up to about two weeks. An airtight container keeps it freshest.
The Easiest Way to Make Cold Brew
You can do all of this with a jar and a sieve. But if you brew cold brew often, a dedicated maker with a built-in filter removes the messiest step — straining. Our favorite for beginners is the Takeya Patented Deluxe: airtight, leakproof, and just three parts.

Troubleshooting Your First Batch
- Too strong? Add more water, milk, or ice. (If you made concentrate, this is normal — dilute it.)
- Too weak or watery? Use more grounds next time, or steep a few hours longer.
- Gritty or muddy? Your grind was too fine. Go coarser, and strain through a paper filter.
- Bitter or woody? You steeped too long. Aim for 16 hours and do not exceed 24.
Frequently Asked Questions
How long does it take to make cold brew?
Active time is about 5 minutes. The steep takes 12–24 hours, so plan to start it the day before you want to drink it. Around 16 hours is a great default.
Can I make cold brew without a special maker?
Absolutely. A large mason jar and a fine-mesh sieve (or paper filter) work perfectly. A dedicated maker just saves you the straining step.
Do I steep cold brew in the fridge or on the counter?
Either works. The fridge is the most foolproof. Room temperature extracts a bit faster, so if you steep on the counter, keep it to about 12–14 hours before refrigerating.
- Grind coarse (like raw sugar), combine with cold water, steep 12–24 hours, then strain.
- Use 1:8 for ready-to-drink cold brew or 1:4 for a concentrate you dilute.
- About 16 hours is the sweet spot; do not exceed 24 hours.
- Store sealed in the fridge — 7–10 days for ready-to-drink, up to 2 weeks for concentrate.
- It is one of the most forgiving coffee methods, so experiment freely.
That is all there is to it. Start a batch tonight and you will have smooth, homemade cold brew waiting for you tomorrow. Once you have the basics down, dial in your ratio and explore the rest of our complete cold brew guide.
