Whether you’re a kombucha enthusiast or a coffee lover looking to branch out, this review will help you decide if this drink is worth trying.
What Is Onyx Cascara Kombucha?
Cascara, also known as coffee cherry tea, is made from the dried skins and pulp of coffee cherries. It has a naturally sweet, fruity flavor with hints of hibiscus, cherry, and raisin. Onyx Coffee Lab has taken this ingredient and fermented it with kombucha cultures, creating a sparkling beverage that’s both refreshing and complex.
The result is a drink that’s less acidic than coffee but more complex than traditional kombucha. It’s a coffee tea hybrid that offers the best of both worlds: the subtle earthiness of coffee and the tangy effervescence of kombucha. Onyx has positioned this as a specialty kombucha, and it’s available in select retail locations and online.
- Cascara is the dried fruit of the coffee cherry, not the bean.
- Kombucha fermentation adds probiotics and a tangy flavor.
- Onyx Cascara Kombucha is a limited-edition release, so grab it when you see it.
Taste Test: What Does It Really Taste Like?
When you first pour Onyx Cascara Kombucha, you’ll notice a deep amber color with a slight cloudiness, typical of unfiltered kombucha. The aroma is immediately fruity, with notes of dark cherries, raisins, and a hint of apple cider vinegar. The first sip is a burst of tangy acidity, followed by a mellow sweetness that’s reminiscent of dried figs.
The carbonation is moderate, giving it a pleasant fizz without being overpowering. As you drink, you’ll notice a subtle earthiness that comes from the coffee cherry, which sets it apart from regular kombucha. The finish is clean and slightly dry, making it a great palate cleanser. Overall, it’s a well-balanced drink that’s both refreshing and intriguing.

- Pair it with dark chocolate to enhance the fruity notes.
- Serve chilled in a wine glass to appreciate the aroma.
- It’s less sweet than commercial kombucha, so expect a dry finish.
How to Brew and Serve Onyx Cascara Kombucha
Onyx Cascara Kombucha is ready to drink straight from the bottle, but you can also use it as a base for creative cocktails or mocktails. For a simple spritzer, mix it with sparkling water and a squeeze of lime. It also pairs well with gin or vodka for a unique coffee cocktail.
If you’re feeling adventurous, you can use it in a marinade for meats or as a glaze for roasted vegetables. The acidity and sweetness make it a versatile ingredient in the kitchen. Just remember to store it in the fridge and consume within a few days of opening to maintain its fizz and flavor.
- Try a cascara kombucha spritz with lime and mint for a refreshing summer drink.
- Use it as a base for a coffee cherry Moscow mule.
- Experiment with it in salad dressings for a tangy twist.
Onyx Cascara Kombucha vs. Traditional Kombucha
Traditional kombucha is typically made from black or green tea, sugar, and a SCOBY. Onyx Cascara Kombucha swaps the tea for cascara, which changes the flavor profile significantly. While traditional kombucha has a more neutral base that takes on the flavor of added fruits or herbs, cascara kombucha has a distinct fruity and slightly earthy taste on its own.
In terms of health benefits, both are fermented and contain probiotics, but cascara also contains antioxidants from the coffee cherry. However, it’s important to note that cascara contains a small amount of caffeine, so it’s not entirely caffeine-free. If you’re sensitive to caffeine, you might want to limit your intake.
- Cascara kombucha has about 25mg of caffeine per 8oz serving, similar to green tea.
- It’s a great alternative for those who want the benefits of kombucha with a unique flavor.
- You can find Onyx Cascara Kombucha at specialty coffee shops and online retailers.
Onyx Cascara Kombucha is a delightful coffee tea hybrid that’s sure to impress. Its unique flavor, health benefits, and versatility make it a standout in the world of specialty kombucha. Whether you’re a coffee connoisseur or a kombucha lover, this drink is worth trying. Keep an eye out for it at your local specialty store or online—it’s a limited release, so don’t miss out!
