Cold brew coffee has gained immense popularity over the years, and for good reason. Its smooth, rich flavor and lower acidity make it a favorite among coffee enthusiasts. One of the most well-known brands in the cold brew market is STōK, renowned for its bold and refreshing taste. If you’ve ever wondered how to replicate STōK’s signature cold brew at home, you’re in the right place. This guide will walk you through the process step-by-step, while also diving into the science behind cold brew and its potential health benefits.
What is Cold Brew Coffee?
Cold brew coffee is a method of brewing coffee that involves steeping coffee grounds in cold or room temperature water for an extended period, typically 12 to 24 hours. Unlike traditional hot brewing methods, cold brew relies on time rather than heat to extract flavor from the coffee grounds. This results in a smoother, less acidic, and highly caffeinated beverage.
The Science Behind Cold Brew
When coffee is brewed with hot water, the heat accelerates the extraction process, pulling out oils, acids, and compounds that contribute to bitterness. Cold brew, on the other hand, extracts these compounds more slowly, resulting in a mellower flavor profile. Additionally, the lower acidity makes it gentler on the stomach, which is why many people with acid reflux or sensitive stomachs prefer cold brew.
Why STōK Cold Brew Stands Out
STōK has mastered the art of cold brew by focusing on three key elements: high-quality beans, precise brewing ratios, and optimal steeping times. Their cold brew is known for its bold, chocolatey notes and smooth finish. To replicate STōK’s cold brew at home, you’ll need to pay attention to these same details.
Ingredients and Equipment You’ll Need
Before diving into the brewing process, gather the following ingredients and tools:
Ingredients
Coffee Beans: Use high-quality, freshly roasted coffee beans. STōK often uses a blend of Arabica beans for a balanced flavor.
Water: Filtered water is best to avoid any impurities that could affect the taste.
Equipment
Coarse Coffee Grinder: A burr grinder is ideal for achieving a consistent coarse grind.
Large Jar or Pitcher: A glass or food-grade plastic container works well.
Fine-Mesh Strainer or Cheesecloth: For filtering out the coffee grounds.
Optional: A coffee filter or nut milk bag for an even cleaner brew.
Step-by-Step Guide to Making Cold Brew Like STōK
Step 1: Choose the Right Coffee Beans
The foundation of any great cold brew is high-quality coffee beans. STōK uses a blend of Arabica beans, which are known for their smooth and slightly sweet flavor. Look for beans with tasting notes of chocolate, caramel, or nuts to mimic STōK’s profile.
Step 2: Grind the Beans Coarsely
Grind your coffee beans to a coarse consistency, similar to breadcrumbs. A coarse grind is essential for cold brew because it prevents over-extraction, which can lead to bitterness. If the grind is too fine, it can also make filtering more difficult.
Step 3: Measure the Coffee-to-Water Ratio
STōK uses a specific coffee-to-water ratio to achieve its signature strength. A good starting point is a 1:4 ratio (1 part coffee to 4 parts water). For example, if you use 1 cup of coffee grounds, you’ll need 4 cups of water. Adjust the ratio to suit your taste preferences.
Step 4: Combine Coffee and Water
Place the coarse coffee grounds in your jar or pitcher, then pour in the filtered water. Stir gently to ensure all the grounds are fully saturated. Cover the container with a lid or plastic wrap.
Step 5: Steep for 12-24 Hours
Let the coffee steep at room temperature for 12 to 24 hours. The longer the steeping time, the stronger and more concentrated the brew will be. STōK typically steeps its cold brew for around 20 hours to achieve the perfect balance of flavor and strength.
Step 6: Strain the Coffee
After steeping, strain the coffee using a fine-mesh strainer or cheesecloth to remove the grounds. For an even cleaner brew, you can strain it a second time through a coffee filter or nut milk bag.
Step 7: Dilute and Serve
STōK cold brew is often served as a concentrate, which can be diluted with water or milk to taste. A common ratio is 1 part cold brew concentrate to 1 part water or milk. Add ice and enjoy!
Tips for Perfecting Your Cold Brew
Experiment with Beans: Try different coffee bean varieties to find your preferred flavor profile.
Adjust Steeping Time: If your brew is too weak, steep it longer next time. If it’s too strong, reduce the steeping time.
Store Properly: Cold brew can be stored in the refrigerator for up to two weeks. Keep it in an airtight container to maintain freshness.
Health Benefits of Cold Brew Coffee
Cold brew coffee isn’t just delicious—it also offers several health benefits. Here’s a closer look at why cold brew might be a healthier choice for some people:
Lower Acidity
Cold brew coffee is significantly less acidic than hot-brewed coffee. This makes it easier on the stomach and may reduce the risk of acid reflux or heartburn.
Rich in Antioxidants
Coffee is a major source of antioxidants, which help combat oxidative stress and inflammation in the body. Cold brew retains these beneficial compounds, making it a healthy beverage choice.
Boosts Metabolism
The caffeine in cold brew can boost your metabolism and enhance physical performance. It also stimulates the central nervous system, improving focus and alertness.
May Improve Heart Health
Some studies suggest that moderate coffee consumption may reduce the risk of heart disease. The antioxidants in coffee can help improve blood vessel function and reduce inflammation.
Common Mistakes to Avoid
While making cold brew is relatively simple, there are a few pitfalls to watch out for:
Using the Wrong Grind Size: A fine grind can lead to over-extraction and a bitter taste.
Skipping the Filtering Step: Failing to strain the coffee properly can result in a gritty texture.
Over-Diluting: Be mindful of the dilution ratio to avoid a weak and watery brew.
Conclusion
Making cold brew like STōK at home is easier than you might think. By using high-quality beans, the right coffee-to-water ratio, and a patient steeping process, you can create a smooth, bold, and refreshing cold brew that rivals your favorite store-bought brand. Plus, with its lower acidity and potential health benefits, cold brew is a great addition to your daily routine. So, grab your coffee beans and start brewing—your perfect cup of cold brew is just a few steps away!
By following this guide, you’ll not only master the art of cold brew but also gain a deeper appreciation for the science and craftsmanship behind it. Whether you’re a coffee novice or a seasoned barista, making cold brew at home is a rewarding experience that’s well worth the effort. Cheers to your next cup of homemade STōK-style cold brew!
