How To Make Starbucks Cold Brew Coffee – Using Coarse Ground Beans

If you want to learn how to make Starbucks cold brew coffee at home, you’re in the right place. Making Starbucks-style cold brew coffee requires coarsely ground beans steeped in cold water for an extended period, yielding a less acidic, concentrated coffee. This guide will walk you through the exact methods and tips to replicate that smooth, signature taste.

The process is surprisingly simple. It requires patience more than anything else. With a few key pieces of equipment and the right coffee, you can have a constant supply of your favorite drink.

How To Make Starbucks Cold Brew Coffee

Starbucks cold brew is known for its exceptionally smooth and chocolatey flavor profile. The secret lies in their specific blend, coarse grind, and long, cold steeping process. By following a few precise steps, you can create a concentrate that mirrors the coffeehouse experience.

You will need to start with the correct ingredients. The quality of your coffee beans is the most important factor. While you can use any coffee, choosing the right type makes a significant difference in the final cup.

Essential Equipment And Ingredients

You don’t need professional barista gear to make great cold brew. Most items are probably already in your kitchen. Here is what you’ll need to get started.

Required Equipment

  • A large container or jar: A 2-quart glass jar or pitcher works perfectly.
  • Fine-mesh strainer: For the initial separation of grounds.
  • Cheesecloth, a nut milk bag, or a dedicated cold brew filter: For a completely grit-free result.
  • A measuring cup and spoon.
  • Optional: A dedicated cold brew coffee maker, which simplifies the straining process.

Required Ingredients

  • Coarsely ground coffee: 1 cup of grounds. This is crucial for proper extraction and easy filtering.
  • Cold, filtered water: 4 cups of water. The quality of your water directly affects taste.
  • Optional: A pinch of sea salt. This is a little-known trick that can enhance the natural sweetness and reduce any residual bitterness.

Choosing The Right Coffee Beans

Starbucks uses a custom blend for its cold brew. While the exact recipe is proprietary, you can get very close by selecting beans with similar characteristics.

Look for a medium to dark roast coffee bean. Starbucks typically uses their Cold Brew Blend, which is a mix of Latin American and African beans. You can use Starbucks beans you buy at the store, or choose a high-quality, pre-ground cold brew blend from other roasters.

If you buy whole beans, you must grind them coarsely. A grind similar to raw sugar or sea salt is ideal. A fine grind will result in over-extraction and a muddy, bitter concentrate. It can also make straining very difficult.

Step-By-Step Brewing Instructions

Now for the main process. This is a hands-off method that does the work while you sleep or go about your day. Follow these numbered steps for the best results.

  1. Combine the coffee and water. In your large jar, add 1 cup of coarsely ground coffee. Slowly pour in 4 cups of cold, filtered water, ensuring all the grounds are fully saturated. Stir gently with a long spoon to mix.
  2. Steep at room temperature. Cover the jar with a lid or plastic wrap. Let it steep at room temperature for 20 to 24 hours. Do not refrigerate during this initial steep, as the colder temperature slows extraction too much.
  3. Strain the concentrate. After steeping, place your fine-mesh strainer over a large bowl or pitcher. Line it with cheesecloth or a nut milk bag. Slowly pour the cold brew mixture through the filter to catch the grounds.
  4. Press and filter. Gather the edges of the cloth and gently squeeze to extract every last drop of concentrate. For a super-clean result, you can filter the liquid a second time through a clean filter.
  5. Dilute and serve. Your result is a strong cold brew concentrate. To serve, fill a glass with ice. Pour the concentrate over the ice, diluting it with water or milk at a 1:1 ratio (equal parts concentrate and water/milk). Adjust to your taste preference.
  6. Store the rest. Transfer the remaining concentrate to a sealed bottle or jar. It will keep fresh in the refrigerator for up to two weeks.

Common Mistakes To Avoid

Even a simple process can have pitfalls. Avoiding these common errors will ensure your cold brew is smooth and delicious every single time.

  • Using finely ground coffee: This is the number one mistake. It leads to over-extraction and a sludgy texture.
  • Steeping for too short or too long: Under 18 hours and it will be weak; over 24 hours and it can become bitter. Aim for the 20-24 hour window.
  • Not filtering properly: Skipping the cheesecloth or using a too-coarse strainer will leave sediment in your drink.
  • Using hot water: The entire point is a slow, cold extraction. Hot water will brew the coffee immediately and create a different, often bitter, flavor profile.
  • Storing at room temperature after straining: Once brewed, the concentrate must be refrigerated to prevent spoilage and maintain flavor.

Customizing Your Homemade Cold Brew

One of the best parts of making coffee at home is customization. You can tailor your drink exactly to your liking, something that can get expensive at a coffee shop.

Starbucks-Inspired Flavor Additions

To mimic popular Starbucks cold brew orders, try these simple additions when you dilute and serve your concentrate.

  • Vanilla Sweet Cream Cold Brew: Add a half teaspoon of vanilla syrup to your glass. Dilute with cold water, then top with a splash of homemade sweet cream (made by whisking together 1/2 cup heavy cream, 2 tablespoons of milk, and 1 tablespoon of vanilla syrup until frothy).
  • Salted Caramel Cream Cold Brew: Add caramel syrup to the glass. Dilute with water, then top with a salted vanilla sweet cream.
  • Chocolate Cream Cold Brew: Add mocha sauce to the glass. Dilute with water and top with plain cold foam or chocolate cold foam.

Creating The Perfect Cold Foam

Cold foam is a hallmark of many Starbucks cold brew drinks. It’s easy to make at home with or without special equipment.

For a simple version, combine 1/4 cup of cold milk (2% or nonfat works best) with a teaspoon of vanilla syrup in a small, deep jar. Seal the lid tightly and shake vigorously for 30-45 seconds until frothy. Alternatively, use a handheld milk frother. Gently pour the foam over the top of your prepared cold brew.

Storing Your Cold Brew Concentrate

Proper storage is key to enjoying your cold brew for up to two weeks. Always store the undiluted concentrate in a clean, airtight container in the refrigerator. Glass jars or bottles with tight-sealing lids are ideal.

Do not add milk or cream to the main concentrate batch, as dairy will spoil much faster. Only add these when you are ready to serve an individual glass. If you notice any off smells or flavors, it’s best to discard the batch and start fresh.

Frequently Asked Questions

What kind of coffee does Starbucks use for cold brew?

Starbucks uses a proprietary Cold Brew Blend, which is a mix of beans from Latin America and Africa. You can purchase Starbucks Cold Brew Blend beans in many grocery stores or use any high-quality, coarsely ground medium-dark roast coffee as a substitute.

How long should you steep cold brew coffee?

The ideal steeping time for cold brew is between 20 and 24 hours at room temperature. Steeping for less time may result in a weak flavor, while steeping for longer can lead to excessive bitterness. The 20-hour mark is often a great starting point.

Can you make cold brew with regular ground coffee?

You should not use pre-ground coffee meant for drip machines, as it is typically a medium grind. For cold brew, you need a specifically coarse grind. If you only have regular ground coffee, your brew time should be much shorter—around 12 hours—to avoid bitterness, but the texture may still be slightly gritty.

Why is my homemade cold brew bitter?

Bitterness in cold brew usually comes from three sources: using too fine of a coffee grind, steeping for too long (over 24 hours), or using poor-quality or over-roasted beans. Ensure your grind is coarse, time your steep, and start with fresh, good-quality coffee beans for a smoother result.

What is the coffee to water ratio for cold brew?

The standard ratio for a cold brew concentrate is 1 part coffee to 4 parts water by volume (e.g., 1 cup coffee to 4 cups water). This creates a strong concentrate meant to be diluted with water or milk when served. For a ready-to-drink brew, you can use a 1:8 ratio, but the concentrate method offers more flexibility.
