If you’ve ever wondered what coffee does Starbucks use for cold brew, you’re not alone. Starbucks uses a particular, coarsely ground coffee blend optimized for their cold brew extraction process. The result is that signature smooth, rich, and slightly chocolatey cup that has become a warm-weather staple. This article will explain exactly which beans they choose, why they work so well, and how you can try to replicate that flavor at home.
The magic of Starbucks Cold Brew isn’t just in the long steeping time. It starts with the coffee bean itself. The company selects specific beans and roasts them in a way that stands up to cold water extraction, which highlights different flavors than hot brewing. Let’s look at what makes their choice so special.
What Coffee Does Starbucks Use For Cold Brew
Starbucks has confirmed that their primary coffee for cold brew is a unique blend called Starbucks Cold Brew Blend. This isn’t a single-origin bean but a crafted combination of beans from Latin America and Africa. The key characteristics of this blend are its low acidity and naturally sweet, chocolatey notes, which are perfect for a slow, cold extraction.
The beans are roasted to a medium level. This is crucial. A light roast might be too bright and acidic when brewed cold, while a very dark roast could become bitter. The medium roast provides a balanced foundation, allowing the smoother, sweeter flavor profile to shine through without harshness. The grind size is also specifically calibrated—it’s very coarse, similar to sea salt, which allows for proper water flow and extraction during the long steeping period.
The Starbucks Cold Brew Blend Profile
Understanding the flavor profile helps explain why this blend is the chosen one. Starbucks describes it as having notes of dark chocolate and citrus. The cold brewing process mutes the citrus acidity and amplifies the chocolate and sweet, rounded body. This creates that distinctively smooth taste that is less bitter and less acidic than iced coffee, which is simply hot-brewed coffee poured over ice.
The blend is typically available for purchase in whole bean form at Starbucks retail locations and online. However, its availability can sometimes be seasonal or vary by region. If you can’t find the official Cold Brew Blend, baristas and the company itself recommend a close alternative.
The Official Starbucks Cold Brew Method
Starbucks steeps its cold brew for a full 20 hours. This extended time is non-negotiable for their standard. The coarse grounds are steeped in cold, filtered water at room temperature or in a cool environment. This slow process extracts the sugars, oils, and subtle flavors from the coffee grounds while leaving behind most of the acids and bitter compounds that are soluble only at higher temperatures.
After steeping, the concentrate is double-filtered to remove all sediment, resulting in a clean, strong liquid. In stores, this concentrate is typically diluted with water when served. The standard ratio is usually one part cold brew concentrate to one part water, but this can be customized. The Nitro Cold Brew is infused with nitrogen gas from a tap, which gives it a creamy, cascading texture without any added dairy or sugar.
How To Make Starbucks-Style Cold Brew At Home
You can make a very close approximation of Starbucks Cold Brew in your own kitchen. It requires patience but very little active effort. The main components are the right coffee, the right grind, the right ratio, and the right time.
Choosing Your Coffee Beans
Your first goal is to find a bean with a similar profile. Look for these characteristics:
- Blend or Single-Origin: A blend of Latin American and African beans is ideal. Look for descriptions mentioning “balanced,” “smooth,” or “chocolate.”
- Roast Level: Stick to a medium roast. Avoid French or Italian dark roasts, as they can become overly bitter with cold brewing.
- Flavor Notes: Descriptors like cocoa, nuts, caramel, or brown sugar are good signs. Avoid beans with prominent fruity or wine-like notes if you want the classic Starbucks taste.
If you cannot find the official Starbucks Cold Brew Blend, a popular and widely available substitute that baristas often recommend is Starbucks® Guatemala Antigua. It’s a single-origin medium roast with notes of cocoa and soft spice that performs excellently as a cold brew.
The Step-By-Step Home Brewing Guide
Follow these steps for a reliable, smooth batch of homemade cold brew concentrate.
- Grind Your Coffee: Use a coarse grind. If you buy pre-ground, look for an option labeled “cold brew” or “French press.” The grounds should look and feel like rough breadcrumbs or sea salt.
- Measure Your Ratio: A standard ratio is 1 cup of coarse coffee grounds to 4 cups of cold, filtered water. This makes a concentrate. You can adjust this slightly based on your taste preference.
- Combine and Steep: Add the grounds to a large jar or a dedicated cold brew pitcher. Pour the water over them, ensuring all grounds are saturated. Stir gently to combine.
- Cover and Wait: Seal the container with a lid or plastic wrap. Let it steep at room temperature or in the refrigerator for 18-24 hours. Steeping in the fridge takes longer but is safer. Starbucks does 20 hours, which is a great target.
- Strain the Coffee: After steeping, strain the mixture through a fine-mesh sieve lined with a coffee filter, cheesecloth, or a nut milk bag. This may take some time as the thick concentrate drips through. A second straining ensures a grit-free result.
- Store and Serve: Transfer the finished concentrate to a clean bottle or jar. It will keep in the refrigerator for up to two weeks. To serve, dilute with an equal part water, milk, or your favorite creamer over ice.
Common Home Brewing Mistakes To Avoid
- Using a Fine Grind: This is the biggest error. A fine grind will over-extract and create a bitter, muddy cold brew. It can also clog your filter.
- Steeping Too Long: While 20 hours is ideal, steeping for more than 24 hours (especially at room temp) can lead to off-flavors and excessive bitterness.
- Inadequate Straining: Skipping the fine-filter step will leave sediment in your concentrate, making the final cup gritty and unpleasent.
- Using Tap Water: Since coffee is over 98% water, the quality matters. Use filtered water for the best, cleanest taste.
Why Starbucks Cold Brew Tastes Different From Iced Coffee
Many people use the terms “cold brew” and “iced coffee” interchangeably, but they are fundamentally different products. Understanding this explains why Starbucks Cold Brew has its unique appeal.
The Brewing Temperature Difference
Iced coffee is made by brewing hot coffee (often at double strength) and then cooling it down rapidly by pouring it over ice. This method extracts all the flavors, acids, and bitterness that hot water can pull from the beans. When poured over ice, it can sometimes taste diluted or sharp.
Cold brew, on the other hand, is never exposed to heat. The cold water extraction over many hours pulls out primarily the sugars and flavorful oils, resulting in a beverage that is inherently about 67% less acidic. This is why it tastes naturally smoother and sweeter, without the need for added sugar to balance acidity.
Flavor And Caffeine Content
The flavor profile is more mellow and rounded. While a hot-brewed coffee might have bright, fruity, or floral notes, those are often muted in cold brew. Instead, you get deeper, richer notes like dark chocolate, molasses, or nuts.
Regarding caffeine, cold brew concentrate is typically higher in caffeine per ounce than regular hot coffee because of the high coffee-to-water ratio. However, when served diluted (as Starbucks does), a grande Cold Brew has slightly more caffeine than a grande hot brewed coffee, but the difference is not extreme. The lack of acidity also makes it easier on the stomach for many people.
Frequently Asked Questions (FAQ)
Can I Buy Starbucks Cold Brew Coffee Beans?
Yes, you can. Starbucks sells its Cold Brew Blend in whole bean form at many retail stores and online. Availability can vary, so it’s best to check with your local store or the Starbucks website. If it’s out of stock, the Guatemala Antigua blend is the recommended alternative.
What Is The Best Grind For Cold Brew?
The best grind for cold brew is a very coarse grind. It should resemble raw sugar or rough sand. A coarse grind allows for a slow, even extraction without over-extracting bitter compounds and makes the final filtering process much easier and cleaner.
How Long Does Starbucks Cold Brew Last?
When you buy a bottle of Starbucks Cold Brew concentrate from the grocery store, it has a printed expiration date and should be consumed by then. For homemade cold brew concentrate, it will stay fresh and flavorful in a sealed container in the refrigerator for up to two weeks. Always give it a sniff test if you’re unsure.
Is Starbucks Cold Brew Sweetened?
The core Starbucks Cold Brew (the black, unsweetened version) is not sweetened. It is simply the diluted cold brew concentrate over ice. However, Starbucks offers many sweetened and flavored variations, like the Vanilla Sweet Cream Cold Brew, which have syrups and creams added. You can always customize your drink to be unsweetened.
Why Is My Homemade Cold Brew Bitter?
If your homemade cold brew tastes bitter, the most likely culprits are:
- The grind is too fine.
- The steeping time was too long.
- The coffee beans were roasted too dark.
- The water used was too warm during steeping.
Try adjusting these variables one at a time, starting with a coarser grind and a shorter steep time of 18 hours.
Final Thoughts On Starbucks Cold Brew Coffee
So, what coffee does Starbucks use for cold brew? The answer is their specially crafted Cold Brew Blend, a medium-roast combination of Latin American and African beans ground extra coarse. The secret to its iconic smoothness lies in this bean selection and the patient 20-hour cold water steep.
The good news is that you don’t need a commercial setup to enjoy something similar. By choosing a medium-roast bean with chocolatey notes, grinding it coarsely, and steeping it for around 20 hours, you can create a remarkably smooth and refreshing cold brew concentrate at home. Remember, the key is in the slow extraction—it’s a simple process that rewards patience with a deliciously smooth cup of coffee, every single time.
