Simple Cold Brew Coffee Recipe for Pitchers

Quick answer

• Use a 1:4 coffee-to-water ratio for a strong concentrate.
• Coarse ground coffee is key. Think sea salt consistency.
• Steep for 12-24 hours at room temperature or in the fridge.
• Filter it well. Paper filters or a fine-mesh sieve work.
• Dilute your concentrate with water or milk to taste.
• Start with a clean pitcher and equipment.

Who this is for

• Anyone who loves smooth, low-acid coffee.
• Folks who want to prep coffee ahead of time for busy mornings.
• Home brewers looking for a simple, forgiving method.

What to check first

• Brewer type and filter type: For pitchers, you’re usually just using the pitcher itself and then a separate filtering method. A fine-mesh sieve is common, or you can line one with cheesecloth or a coffee filter. Make sure whatever you use is clean and won’t clog too easily. I like using a dedicated cold brew maker with a built-in filter, but a simple pitcher and sieve works fine.
• Water quality and temperature: Use filtered water. Tap water can have off-flavors that will come through in your cold brew. Temperature matters less for cold brew since it’s, well, cold. Room temperature or fridge temps are both good.
• Grind size and coffee freshness: This is a big one. You want a coarse grind, like coarse sea salt or breadcrumbs. Too fine, and you’ll get sludge and over-extraction. Freshly ground beans are always best, but for cold brew, even pre-ground can work in a pinch if it’s not too old.
• Coffee-to-water ratio: A common starting point is 1:4 (coffee to water by weight). This makes a concentrate that you’ll dilute later. Some go 1:5 or even 1:8 for a less intense concentrate. Experiment to find your sweet spot.
• Cleanliness/descale status: Any old coffee oils or residue can make your cold brew taste bitter or stale. Give your pitcher and any filtering equipment a good wash before you start. If you’ve got a machine, make sure it’s descaled according to the manufacturer’s instructions.

For this recipe, you’ll need a good pitcher to do the steeping. A simple glass pitcher works perfectly for making cold brew concentrate.

Step-by-step (brew workflow)

1. Gather your gear: You’ll need a pitcher, coffee grounds, filtered water, and a way to filter the grounds out later. A scale is helpful for precision, but you can eyeball it.

• What “good” looks like: Everything is clean and ready to go. You know your ratio.
• Common mistake: Using dirty equipment. This ruins the taste. Always wash up first.

2. Measure your coffee: For a 1:4 concentrate, if you’re using 4 oz of coffee, you’ll need 16 oz of water. A standard 32 oz pitcher might use 8 oz of coffee and 32 oz of water for a strong batch.

• What “good” looks like: Coffee measured out, ready for the water.
• Common mistake: Guessing the amount. This leads to inconsistent brews. Use a scale if you can.

3. Add coffee to the pitcher: Dump your coarsely ground coffee into the clean pitcher.

• What “good” looks like: All the coffee is in the pitcher.
• Common mistake: Not using a coarse grind. You’ll get sediment and bitterness.

4. Add water: Pour your filtered water over the coffee grounds. Make sure all the grounds are saturated.

• What “good” looks like: All the grounds are wet. No dry pockets.
• Common mistake: Not stirring to ensure all grounds are wet. Some grounds might stay dry and under-extract.

5. Stir gently: Give it a gentle stir to make sure all the coffee grounds are fully immersed in the water. Don’t go crazy; you don’t want to break up the grounds too much.

• What “good” looks like: A uniform mixture of coffee and water.
• Common mistake: Over-stirring, which can lead to finer particles breaking off and making your brew muddy.

6. Cover and steep: Cover the pitcher tightly. You can let it steep at room temperature on your counter or in the refrigerator.

• What “good” looks like: The pitcher is sealed and sitting in its steeping spot.
• Common mistake: Leaving it uncovered. This can let in odors or dust.

7. Steep for 12-24 hours: Longer steeping generally means a stronger, more flavorful brew. 18 hours is a good starting point for many.

• What “good” looks like: The coffee has had ample time to extract.
• Common mistake: Steeping too short. You’ll get weak, watery coffee. Steeping too long can lead to bitterness.

8. Prepare for filtering: Set up your filtering setup. This might be a fine-mesh sieve over another container, or a sieve lined with cheesecloth or a paper filter.

• What “good” looks like: Your filtering station is ready.
• Common mistake: Using a filter that’s too fine for the amount of liquid, leading to slow draining or clogs.

9. Filter the coffee: Slowly pour the steeped coffee mixture through your filter. You might need to do this in batches.

• What “good” looks like: The grounds are separated from the liquid.
• Common mistake: Rushing the filtering process. This can push fine sediment through.

10. Discard grounds: Once filtered, discard the spent coffee grounds.

• What “good” looks like: All grounds are out of your concentrate.
• Common mistake: Not filtering thoroughly enough. You’ll end up with sludge in your cup later.

11. Dilute to taste: Your filtered liquid is a concentrate. Pour some into a glass with ice. Add water or milk to your liking. A 1:1 or 1:2 ratio of concentrate to diluent is common.

• What “good” looks like: A balanced, delicious cup of coffee.
• Common mistake: Drinking the concentrate straight. It’s super strong!

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Using fine coffee grounds	Muddy brew, over-extraction, bitter taste, sludge	Use coarse grounds (sea salt consistency).
Incorrect coffee-to-water ratio	Weak or overly strong concentrate	Start with 1:4 (coffee:water) and adjust.
Insufficient steeping time	Weak, watery, underdeveloped flavor	Steep for at least 12 hours, ideally 18-24.
Over-steeping	Bitter, astringent, unpleasant flavor	Stick to the 12-24 hour window. Taste test at 12 hours.
Not saturating all grounds	Uneven extraction, weak spots, wasted coffee	Stir gently after adding water to ensure all grounds are wet.
Using dirty equipment	Off-flavors, stale taste, potential mold growth	Wash pitcher and filters thoroughly before brewing.
Not filtering thoroughly	Sediment in the final cup, gritty texture	Filter slowly, possibly in batches. Use a fine-mesh sieve.
Storing without a lid	Absorbs fridge odors, can dry out, contamination	Always cover your pitcher tightly.
Not diluting the concentrate	Extremely strong, undrinkable coffee	Dilute with water or milk to your preferred strength.
Using stale coffee	Flat, dull, or off-flavors in the final brew	Use freshly roasted beans if possible, or at least not very old.

Decision rules (simple if/then)

• If your cold brew tastes weak, then add a little more coffee next time because you might need a stronger ratio.
• If your cold brew tastes too bitter, then reduce your steeping time or ensure your grounds are coarse enough because over-extraction is likely.
• If you see a lot of sediment in your finished coffee, then filter it again more slowly or use a finer filter next time because you might not be removing all the fine particles.
• If your coffee smells like your refrigerator, then make sure to cover your pitcher tightly next time because it likely absorbed odors.
• If you’re in a hurry, then steep for the minimum 12 hours, but know that longer steeping usually yields better results because flavor develops over time.
• If you prefer a smoother, less acidic coffee, then cold brew is definitely the way to go because the cold water extraction process reduces acidity.
• If you want a stronger concentrate, then increase the coffee-to-water ratio (e.g., go from 1:4 to 1:3) because more coffee means a more concentrated brew.
• If you’re using pre-ground coffee and it tastes a bit dull, then try grinding your own beans coarsely next time because freshness makes a difference.
• If you notice a slightly metallic taste, then check your water quality because tap water can sometimes impart unwanted flavors.
• If you want to experiment with flavor, then consider adding a cinnamon stick or a few cardamom pods to the grounds before steeping because botanicals can add subtle notes.

FAQ

What’s the best coffee bean for cold brew?

Medium to dark roasts often work well, offering chocolatey or nutty notes. However, you can use any bean you enjoy. The key is the coarse grind and brew method.

How long does cold brew last in the fridge?

Your cold brew concentrate should last about 1-2 weeks when stored properly in a sealed container in the refrigerator. Always check for off smells or tastes before consuming.

Can I use hot water to speed up cold brew?

No, that defeats the purpose of cold brew. Using hot water will extract different compounds, leading to a hot coffee flavor profile and potentially bitterness. Stick to cold or room temperature water.

Why is my cold brew cloudy?

This is usually due to using grounds that are too fine or not filtering thoroughly enough. The fine particles slip through the filter, making the brew cloudy.

What’s the difference between cold brew concentrate and ready-to-drink cold brew?

Concentrate is a strong, undiluted brew that needs to be diluted with water or milk before drinking. Ready-to-drink is already diluted to a drinkable strength.

Can I reuse the coffee grounds?

While you can technically steep them again, the flavor will be significantly weaker and less complex. It’s generally not recommended for good tasting coffee.

Do I need a special cold brew maker?

Nope! A simple pitcher, a sieve, and some patience work perfectly well. Dedicated makers can be convenient but aren’t essential for great cold brew.

How much caffeine is in cold brew?

Cold brew typically has more caffeine than drip coffee, especially if you’re drinking the concentrate. The exact amount varies based on the coffee-to-water ratio and steeping time.
