What Is Royal Flush? An Overview of Diverse Products
The name "Royal Flush" is used across several different product categories, leading to confusion about its caffeine content. Unlike a single product with a consistent formula, the caffeine level is entirely determined by which specific Royal Flush you are consuming.
Royal Flush Kombucha by REAL Drinks Co.
This is a non-alcoholic sparkling fermented tea brewed from First Flush Darjeeling tea, known as the "Queen of Teas". As a tea-based product, it is not caffeine-free, but the fermentation process significantly reduces the caffeine level. The manufacturer states that their Royal Flush contains about one-fifth to one-sixth the caffeine of a typical cup of coffee. This results in a much lower caffeine kick compared to a standard coffee or tea, but it is still present.
The East India Company's Royal Flush Black Tea
This product is a loose-leaf black tea blend. All black tea naturally contains caffeine, and The East India Company explicitly states this in their product FAQs. The caffeine level in this product is generally comparable to other traditional black teas, which typically contain 40-70mg of caffeine per 8-ounce cup, depending on the brewing time and strength.
Royal Flush Cold-Pressed Juice
Offered by companies like Green Press, this is a cold-pressed vegetable and fruit juice blend. The ingredients for this juice typically include spinach, beets, celery, and apple, which are naturally caffeine-free. Therefore, this version of Royal Flush contains no caffeine.
Royal Flush IV Therapy
This is a medical or wellness intravenous infusion therapy offered by clinics like REVIV. It contains a blend of vitamins, minerals, and antioxidants, but no caffeine. The purpose of this treatment is for detoxification and recovery, not for providing a caffeine boost.
Caffeine Comparison: Royal Flush vs. Other Beverages
To better understand the caffeine levels associated with the different products named Royal Flush, here is a comparative table.
| Beverage | Typical Caffeine Content per 8 fl oz | Royal Flush Product Type | Caffeine Present? | Source Tea/Ingredients |
|---|---|---|---|---|
| Brewed Coffee | 95 mg | N/A | High | Coffee Beans |
| Black Tea | 40-70 mg | Loose Leaf Black Tea | Moderate | Black Tea Leaves |
| Real Kombucha Royal Flush | ~1.5–3 mg/oz (10-25mg/8oz) | Fermented Sparkling Tea | Low | First Flush Darjeeling Tea |
| Decaf Coffee | ~2 mg | N/A | Very Low | Decaffeinated Coffee |
| Royal Flush Juice | 0 mg | Cold-Pressed Juice | No | Fruits & Vegetables |
| Royal Flush IV | 0 mg | IV Drip Therapy | No | Vitamins & Minerals |
Factors Influencing Caffeine in Kombucha
For the caffeinated kombucha versions, several factors can influence the final caffeine content:
- Type of tea used: Kombucha is traditionally brewed from black or green tea, both of which contain caffeine. The manufacturer of REAL Royal Flush uses Darjeeling tea.
- Brewing time: The length of the initial tea brewing process before fermentation affects how much caffeine is extracted from the leaves.
- Fermentation process: The yeast and bacteria cultures in the SCOBY (Symbiotic Culture of Bacteria and Yeast) consume some of the caffeine during fermentation. This is why kombucha has less caffeine than the tea it was brewed from.
- Brewing temperature: The temperature at which the tea is brewed can also influence the rate of caffeine extraction.
Making the Right Choice for Your Caffeine Needs
If you are mindful of your caffeine intake, it is crucial to identify the specific Royal Flush product you intend to consume. For those seeking a rich tea flavor with a moderate caffeine level, the loose-leaf black tea is the appropriate choice. If you prefer a very low-caffeine, fermented beverage with probiotic benefits, the sparkling kombucha is the better option. For those who need to avoid caffeine entirely, a cold-pressed juice version is available. Always check the ingredients and product description to confirm what you are getting.
Conclusion
The name "Royal Flush" does not indicate a specific caffeine content, as it is used for a range of products with vastly different formulations. While the REAL Kombucha version contains a small amount of caffeine from its Darjeeling tea base, and The East India Company's black tea contains a moderate amount, the juice and IV therapy versions are caffeine-free. To be certain about what you are consuming, the best practice is to always read the product label and ingredient list carefully.

How the Fermentation Process Reduces Kombucha Caffeine
- Origin of caffeine: The initial tea leaves used to brew kombucha contain natural caffeine.
- Yeast metabolism: During fermentation, the yeast in the SCOBY consumes some of the available caffeine as a nutrient source.
- Significant reduction: The combined action of brewing at lower strength and the fermentation process means a large portion of the original caffeine is removed.
- Residual amount: A trace amount of caffeine remains in the final product, but it is typically far less than in the starting tea or a cup of coffee.
- Variability: The exact caffeine level in kombucha can fluctuate based on the specific culture used, fermentation time, and the original tea's strength.
Factors Affecting Black Tea Caffeine
- Tea variety: The specific type of black tea leaf (e.g., Darjeeling, Assam) affects initial caffeine content.
- Brewing temperature and time: Steeping black tea for longer periods or at higher temperatures will extract more caffeine.
- Processing: Black tea leaves are fully oxidized, a process that does not remove the inherent caffeine.
Health Implications of Caffeine in Royal Flush Products
- Low-caffeine boost: The kombucha version offers a mild lift without the jitters associated with high-caffeine beverages.
- Energy and focus: The East India Company's black tea can provide a more noticeable energy boost, similar to other black teas.
- Safe for sensitive individuals: Caffeine-free Royal Flush options like the juice are suitable for those with caffeine sensitivities or for consumption at night.
- Alternative benefits: Caffeine-free versions offer other health benefits, such as antioxidants from fruits and vegetables or detoxification properties from IV therapies.
