Starbucks Cold Brew Coffee Copycat Recipe

Making Starbucks cold brew coffee at home takes a little patience but almost zero effort, and the result is a smooth, low-acid concentrate you can keep in the fridge all week.

Once you have the concentrate ready, you’re just minutes away from a cold, slightly sweet coffee that tastes like the real thing, for a fraction of the cost.

Why I Love This Recipe

The concentrate is less bitter than regular iced coffee because the grounds never touch hot water. That slow steep pulls out the sweetness and a kind of chocolatey depth you just don’t get from brewing hot and chilling it down.

This is the version I keep coming back to. It takes about 5 minutes of actual work, and the rest happens in the fridge overnight.

Recipe Ingredients

• 2 cups coarse-ground coffee – Use a medium-dark roast for the closest match to Starbucks; a Sumatra or Espresso Roast works well
• 8 cups cold filtered water – Filtered water makes a noticeable difference; tap works but the flavor is cleaner with filtered
• Ice – For serving; as much as you like
• 1/2 cup cold water (for diluting, per serving) – Cold brew concentrate is strong; this brings it to a drinkable ratio
• 1 to 2 tsp simple syrup (optional, per serving) – Starbucks uses their own vanilla-free classic syrup, which is just equal parts sugar and water
• 2 tbsp heavy cream or milk (optional, per serving) – Adds richness; leave it out to keep it black

Variations / Substitutions

• Light roast instead of medium-dark – You’ll get a brighter, more acidic cup with floral notes rather than chocolatey depth.
• Oat milk instead of heavy cream – Works great; adds a mild sweetness and keeps it dairy-free without watering down the flavor.
• Brown sugar syrup instead of simple syrup – Stir together 1 cup brown sugar with 1 cup hot water until dissolved; it adds a light caramel note.
• Vanilla sweet cream cold foam – Blend 2 tbsp heavy cream, 1 tbsp vanilla syrup, and a splash of 2% milk until foamy, then spoon it over the top. This is the base for the Starbucks Vanilla Sweet Cream Cold Brew, if that’s the version you’re after.
• Unsweetened – Skip the syrup entirely; the concentrate has enough natural sweetness from the slow steep that many people don’t miss it.

How To Make Cold Brew Coffee

Step 1: Combine the Coffee and Water

Add the 2 cups coarse-ground coffee to a large jar, pitcher, or French press. Pour in the 8 cups cold filtered water and stir gently for about 30 seconds until all the grounds are wet.

There’s no heat here, so the grounds just need contact with the water. You’ll see some floating at the top at first; that’s fine. Once you stir, most will sink.

Step 2: Steep the Grounds Overnight

Cover the jar with a lid or plastic wrap and transfer it to the fridge. Let it steep for 18 to 24 hours. The longer you go, the stronger and slightly more bitter the concentrate gets; 20 hours is a reliable sweet spot.

Don’t leave it on the counter. A cold steep in the fridge slows extraction just enough to avoid the harsh, sour notes you’d get at room temperature over the same time.

Step 3: Strain the Concentrate

Set a fine-mesh strainer lined with a coffee filter or cheesecloth over a large bowl or second pitcher. Pour the steeped mixture through slowly. It takes 3 to 5 minutes for the liquid to fully drip through; don’t press or squeeze the grounds or the concentrate will turn cloudy and slightly bitter.

What’s left in the bowl is your concentrate. It should be a deep, dark mahogany with no visible sediment. Discard the grounds and rinse the jar, then pour the concentrate back in for storage.

Step 4: Build and Serve Your Cold Brew

Fill a tall glass with ice. Pour in about 1/2 cup cold brew concentrate, then add the 1/2 cup cold water to dilute it to a standard drinking strength. If you’re adding sweetener, stir in 1 to 2 tsp simple syrup now. Add the 2 tbsp heavy cream or milk if you like, poured slowly over the back of a spoon so it drifts down through the glass.

Serve immediately while the ice is still fresh, and the glass is still frosty.

Recipe Tips

• Use coarse grounds, not medium or fine. Fine grounds slip through even a coffee filter and leave grit in your concentrate; they also over-extract and add bitterness.
• The 1:4 ratio is the key number. Two cups of coffee to 8 cups of water gives you a concentrate that dilutes well 1:1 with water. Scale it up or down keeping that same ratio.
• Don’t skip the second filtration. Running it through a coffee filter after the strainer removes the fine sediment that makes cold brew feel gritty on the back of your throat.
• Taste before you dilute. The concentrate on its own should taste strong and slightly sweet. If it tastes sour or thin, your grind was probably too coarse or the steep was too short.

How To Store

• Refrigerate – Keep the concentrate in a sealed jar or pitcher for up to 2 weeks. The flavor is best in the first 10 days; after that it can develop a slightly flat, stale taste.
• Serve Cold – Cold brew concentrate is meant to be served over ice; no reheating needed. If you want a hot version, dilute the concentrate with hot water 1:1 instead.

What To Serve With Cold Brew Coffee

A slice of something with a little fat and sugar balances the low-acid bitterness of cold brew better than a sweet-only pairing. A buttery croissant or a slice of banana walnut bread works well because the richness softens the coffee’s intensity. If you want something lighter, a plain almond biscotti gives you a bit of crunch without competing with the flavor of the coffee itself.

Frequently Asked Questions

Can I make cold brew without a special brewer?

Yes. A large mason jar and a fine-mesh strainer lined with a coffee filter is all you need; no dedicated cold brew equipment required.

What coffee brand does Starbucks actually use for their cold brew?

Starbucks uses their Nariño 70 Cold Brew blend, which is a Latin American medium-dark roast. A Sumatra or Espresso Roast from any brand is a close match at home.

Can I freeze the concentrate to make it last longer?

Yes. Pour it into an ice cube tray, freeze solid, then transfer the cubes to a bag. Use within 3 months. Drop a few cubes directly into a glass so they melt into the drink without diluting it.

Why does my cold brew taste sour or weak?

Sourness usually means under-extraction: the grind was too coarse, the steep too short, or the coffee-to-water ratio was off. Try steeping for the full 24 hours and check that your grind is genuinely coarse, not medium.

Ingredients Method Notes

Ingredients

  

• 2 cups coarse-ground medium-dark roast coffee
• 8 cups cold filtered water
• Ice, for serving
• 1/2 cup cold water per serving, for diluting
• 1 to 2 tsp simple syrup per serving (optional)
• 2 tbsp heavy cream or milk per serving (optional)

Method

 

1. Combine the 2 cups coarse-ground coffee and 8 cups cold filtered water in a large jar or pitcher. Stir for 30 seconds until all the grounds are wet.
2. Cover and refrigerate for 18 to 24 hours.
3. Strain the steeped mixture through a fine-mesh strainer lined with a coffee filter into a large bowl or second pitcher. Let it drip for 3 to 5 minutes without pressing the grounds, then discard the grounds and transfer the concentrate back to a clean jar.
4. To serve, fill a tall glass with ice, add 1/2 cup concentrate and 1/2 cup cold water, stir in 1 to 2 tsp simple syrup if using, and pour 2 tbsp heavy cream or milk slowly over the top.

Notes

The active prep time here is about 5 minutes; the rest is hands-off fridge time. For the smoothest concentrate, don’t rush the strain through the coffee filter. If you want to prep ahead for the week, a full batch gives you 8 servings and keeps well for up to 10 days in the fridge.
