Simple Cold Brew Coffee Recipe With Regular Grounds

Quick answer

• Use a coarse grind, but regular grounds work in a pinch.
• Aim for a 1:8 coffee-to-water ratio.
• Steep for 12-24 hours at room temp or in the fridge.
• Strain thoroughly. Cold brew concentrate is strong, dilute it.
• Taste and adjust for your next batch.

Who this is for

• Anyone who wants smooth, less acidic coffee without a fancy setup.
• People who have regular coffee grounds on hand and don’t want to buy a special grind.
• Campers or travelers looking for a simple, portable coffee solution.

What to check first

Brewer type and filter type

You can use a French press, a large jar, or even a pitcher. The key is having something to hold the grounds and then strain them out. For straining, cheesecloth, a fine-mesh sieve, or even a clean t-shirt can work. Paper filters can clog, so a reusable or metal filter is often better for cold brew.

Water quality and temperature

Use filtered water if your tap water has a strong taste. Cold brew is mostly water, so good water makes good coffee. Temperature isn’t as critical as hot brew. Room temperature or fridge temps are fine for steeping.

Grind size and coffee freshness

Ideally, you want a coarse grind. Think breadcrumbs or coarse sea salt. But regular grounds? Yeah, they’ll work. They might just make the final brew a bit murkier or harder to strain. Fresher coffee is always better, but cold brew is forgiving.

Coffee-to-water ratio

A good starting point is 1:8. That’s 1 part coffee to 8 parts water by weight. For example, 100 grams of coffee to 800 grams (or ml) of water. If you don’t have a scale, roughly 1 cup of grounds to 4 cups of water is a decent ballpark.

Cleanliness/descale status

Make sure your brewing vessel and any filters are clean. Old coffee oils can go rancid and make your brew taste funky. If you use a machine for hot water to clean, make sure it’s descaled too.

Step-by-step (brew workflow)

1. Measure your coffee grounds.

• What “good” looks like: You have the right amount for your batch size.
• Common mistake: Guessing. This throws off the ratio. Use a scale or at least a consistent measuring cup.

2. Add grounds to your brewing vessel.

• What “good” looks like: All grounds are in the container, ready for water.
• Common mistake: Spilling grounds. Do this over your vessel to catch any strays.

3. Add about half your water.

• What “good” looks like: The grounds are saturated and starting to bloom.
• Common mistake: Adding all the water at once. This can create pockets where grounds don’t get wet.

4. Stir gently.

• What “good” looks like: All grounds are wet and no dry clumps remain.
• Common mistake: Over-stirring or stirring too vigorously. You want to wet the grounds, not agitate them like hot coffee.

5. Add the remaining water.

• What “good” looks like: The vessel is filled to your desired level, covering all grounds.
• Common mistake: Overfilling. Leave some headspace for stirring and to prevent spills.

6. Cover the vessel.

• What “good” looks like: It’s sealed to keep dust and fridge smells out.
• Common mistake: Leaving it uncovered. Bugs or odors can get in. A lid, plastic wrap, or foil works.

7. Steep.

• What “good” looks like: The coffee is steeping undisturbed for 12-24 hours.
• Common mistake: Not steeping long enough. This results in weak, watery coffee. Or steeping too long, which can lead to bitter flavors.

8. Prepare to strain.

• What “good” looks like: You have your straining setup ready over a clean container.
• Common mistake: Not having a clean container ready. You’ll end up with a mess.

9. Strain the coffee.

• What “good” looks like: The liquid is mostly free of grounds. You might need to strain twice for clarity.
• Common mistake: Rushing the strain. This lets more sediment through. Be patient.

10. Discard the grounds.

• What “good” looks like: The grounds are out of the way. Compost them if you can.
• Common mistake: Leaving grounds in the sink. They can clog drains.

11. Dilute the concentrate.

• What “good” looks like: You’ve mixed the strong concentrate with water or milk to your preferred strength.
• Common mistake: Drinking the concentrate straight. It’s usually too strong and can be harsh.

12. Chill and serve.

• What “good” looks like: Cold, refreshing coffee.
• Common mistake: Serving it warm. Cold brew is best chilled.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Using finely ground coffee	Cloudy brew, difficult straining, over-extraction	Use a coarser grind next time. For now, strain twice or accept some sediment.
Not steeping long enough	Weak, watery, sour coffee	Steep for at least 12 hours, up to 24. Adjust time based on taste.
Steeping for too long	Bitter, astringent, unpleasant taste	Reduce steeping time. 18-20 hours is often a sweet spot.
Incorrect coffee-to-water ratio	Too weak or too strong concentrate	Start with 1:8 and adjust. A scale is your best friend here.
Using tap water with off-flavors	Coffee tastes like tap water	Use filtered water. Cold brew highlights water quality.
Not straining thoroughly	Gritty, muddy coffee	Strain multiple times, use a finer filter, or let it settle.
Not cleaning equipment	Rancid, stale coffee flavors	Wash all brewing gear thoroughly after each use.
Drinking concentrate straight	Jitters, stomach upset, overpowering flavor	Dilute with water, milk, or ice. Start with a 1:1 ratio and adjust.
Not covering the brew	Dust, fridge odors, or bugs in coffee	Always cover your brew vessel tightly.
Using stale coffee	Flat, dull flavor	While cold brew is forgiving, very old beans won’t yield great results. Use reasonably fresh beans.

Decision rules (simple if/then)

• If your cold brew tastes weak, then add more coffee to water next time because your ratio might be too dilute.
• If your cold brew tastes too strong, then dilute it more or use less coffee next time because your concentrate is too concentrated.
• If your brew is bitter, then reduce the steeping time or use a coarser grind because you might be over-extracting.
• If your brew is sour, then increase the steeping time or ensure all grounds are saturated because you might be under-extracting.
• If you have sediment in your cup, then strain your brew again with a finer filter because your initial straining wasn’t thorough enough.
• If your coffee smells like your refrigerator, then cover your brew vessel tightly next time because odors can transfer.
• If you’re using regular grounds and they seem to be clogging your filter, then try a coarser grind if possible or strain more gently because fine particles are harder to filter.
• If you experience stomach upset, then dilute your cold brew more or try a different bean because the acidity or strength might be the issue.
• If you want a smoother, less acidic cup, then stick to the recommended steeping times and avoid over-extraction because that’s the key benefit of cold brew.
• If your cold brew tastes flat, then use fresher coffee beans next time because freshness impacts flavor significantly.

FAQ

Can I really use any coffee grounds?

Yes, you can use regular grounds. They might produce a murkier brew and be harder to strain than coarse grounds, but it will still work.

How long should I steep my cold brew?

A good range is 12 to 24 hours. Room temperature steeping is faster than in the fridge. Experiment to find what tastes best to you.

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

A common starting point is 1:8 by weight (e.g., 100g coffee to 800g water). If you don’t have a scale, try about 1 cup of grounds to 4 cups of water.

Do I need special equipment for cold brew?

Nope. A simple jar, pitcher, or French press works fine. A fine-mesh sieve or cheesecloth is handy for straining.

My cold brew tastes bitter. What did I do wrong?

You likely steeped it too long, or your grind might have been too fine. Try a shorter steep time or a coarser grind next time.

My cold brew is weak. How can I fix it?

You probably didn’t steep it long enough, or you used too much water for the amount of coffee. Increase your steeping time or use a stronger coffee-to-water ratio.

Can I make cold brew concentrate without a fancy maker?

Absolutely. A mason jar and a sieve are all you really need. It’s a super simple process.

How long does cold brew last in the fridge?

It’s best consumed within 7-10 days. After that, the flavor can start to degrade.
