If you’re a coffee lover who enjoys the bold, smooth flavor of cold brew, you’ve probably come across STōK Cold Brew Unsweetened. Known for its refreshing and strong taste, STōK has become a popular choice for those seeking a cold brew with an extra boost of caffeine. But how much caffeine does STōK Cold Brew Unsweetened really have, and how does it compare to other coffee beverages? In this article, we’ll explore the caffeine content in STōK Cold Brew, factors that affect its caffeine levels, and what you should know about consuming it.
Caffeine Content Per Serving
STōK Cold Brew Unsweetened is packed with caffeine, offering anywhere from 120 to 170 milligrams (mg) per 12 fl oz serving. This caffeine range is typical for a strong cold brew coffee, though the exact amount can vary depending on factors such as the coffee bean type, brewing method, and concentration of the coffee.
To put this in perspective:
Regular iced coffee typically contains about 80–120 mg of caffeine per 12 oz serving.
Brewed coffee usually has around 95 mg of caffeine per 8 oz cup.
Espresso offers about 63 mg of caffeine per 1 oz shot.
As you can see, STōK Cold Brew Unsweetened provides a higher caffeine kick than regular iced coffee, making it a great choice for those who want a more potent boost.
Comparison with Other Cold Brews
STōK Cold Brew Unsweetened is competitive with other popular cold brew coffee brands in terms of caffeine content. Many cold brews range from 100 to 200 mg of caffeine per 12 oz serving, so STōK’s caffeine levels are right in the middle of the pack. Some brands, like High Brew Coffee, contain around 180 mg per serving, while others like Chameleon Cold-Brew have slightly lower caffeine content.
However, STōK stands out for its smooth and rich flavor. Many cold brews can have an overpowering bitterness, but STōK’s unsweetened variety maintains a clean, crisp taste without the extra sweetness, allowing the coffee’s natural flavors to shine through. For those looking for a strong yet smooth coffee experience, STōK provides a great balance of caffeine and flavor.
Factors Affecting Caffeine Levels
There are several factors that affect the caffeine levels in cold brew coffee. Here are the main variables that contribute to the caffeine content:
1. Coffee Bean Type
The type of coffee bean used plays a significant role in determining caffeine levels. There are two main types of coffee beans: Arabica and Robusta.
Arabica beans are commonly used for cold brew because they offer a smoother, less bitter taste.
Robusta beans tend to have higher caffeine content but also a more bitter flavor.
STōK uses a blend of beans that are typically high in quality and are likely a mix of Arabica and Robusta, contributing to both the bold flavor and higher caffeine content.
2. Grind Size
The size of the coffee grounds influences the extraction process. For cold brew, a coarse grind is typically used. The grind size affects how much caffeine is extracted during the steeping process. Finer grinds tend to result in a stronger extraction of caffeine, but in cold brew, the grind size is larger to slow down the extraction, creating a smoother taste and a more controlled caffeine level.
3. Brewing Time
Cold brew coffee is made by steeping coarsely ground coffee in cold water for an extended period (usually 12 to 24 hours). The longer the coffee grounds sit in water, the more caffeine is extracted. Since STōK Cold Brew is brewed for an extended time, it allows for more caffeine to be pulled from the beans, contributing to its stronger caffeine content.
4. Coffee-to-Water Ratio
The amount of coffee used relative to the amount of water is crucial in determining the strength of the brew. A higher coffee-to-water ratio results in a stronger cold brew, meaning more caffeine in each serving. STōK’s coffee concentrate is likely made with a higher ratio of coffee to water, which explains its potent caffeine punch compared to standard iced coffee.
Health Considerations
Before you reach for that bottle of STōK Cold Brew Unsweetened, it’s important to consider your daily caffeine intake, especially if you’re sensitive to it. According to the U.S. Food and Drug Administration (FDA), the recommended maximum amount of caffeine for a healthy adult is 400 mg per day, which is roughly equivalent to 4 cups of brewed coffee.
Effects of Caffeine on the Body
Energy & Focus: Caffeine is a stimulant that blocks adenosine, a neurotransmitter that promotes sleep. This leads to increased alertness and energy. For many people, a boost in caffeine helps improve focus, productivity, and mental clarity, making it a popular choice for early mornings or mid-afternoon slumps.
Sleep: While caffeine provides an energy boost, it can also interfere with sleep. The half-life of caffeine (the time it takes for half of the caffeine to leave your system) is about 5 to 6 hours, so drinking cold brew late in the day may make it harder to fall asleep.
Digestive Effects: For some, caffeine can stimulate the digestive system and cause upset stomachs or acid reflux. It’s a good idea to drink cold brew on an empty stomach if you don’t have sensitivity to caffeine.
If you’re someone who tends to be sensitive to caffeine, it’s important to monitor your intake and consider adjusting your consumption accordingly.
Serving Size & Consumption Tips
If you’re not accustomed to high-caffeine beverages, it’s a good idea to start with a smaller serving of STōK Cold Brew Unsweetened. For instance, you could start with half a serving (about 6 oz) and see how it affects your energy levels and focus. If you feel energized and alert, you can gradually increase the amount as you get used to the caffeine content.
If you’re sensitive to caffeine or don’t want a strong boost, you can also dilute the cold brew with water or milk, which will lower the caffeine concentration per serving while maintaining the rich flavor.
For those who enjoy iced coffee with a creamier taste, adding a splash of milk or a non-dairy alternative like oat milk is a great way to soften the strong flavor without losing the caffeine kick.
Alternative STōK Products
If you enjoy the flavor and smoothness of STōK Cold Brew but prefer a lower caffeine option, STōK offers a variety of alternatives:
STōK Decaf Cold Brew: For those who enjoy the taste of cold brew but want to avoid the caffeine, the decaf version is an excellent option. It still provides the smooth, rich taste without the jittery side effects of caffeine.
Flavored Cold Brews: STōK also offers flavored cold brew options, like Vanilla and Mocha, which can offer a different take on the cold brew experience. While these still contain caffeine, the flavors can make your cold brew experience more exciting without increasing the caffeine level significantly.
These alternatives allow you to enjoy the signature STōK experience while adjusting your caffeine intake according to your preferences.
