What Does Salted Grapefruit Kombucha Juice Taste Like?
Salted grapefruit kombucha juice tastes sweet and tangy. It’s fizzy and cold—great for a summer afternoon. You’ll taste just a hint of salt that balances the tangy sweetness.
Black tea kombucha brings a strong tea taste. If you prefer, use white or green tea kombucha. The earthy, floral scents will complement the fresh grapefruit juice.
What Are the Health Benefits of Salted Grapefruit Kombucha Juice?
Kombucha is full of antioxidants and probiotics that help your body function at its best. Antioxidants help protect your cells from damage. Probiotics help increase the good bacteria in your gut, which helps improve digestion and overall health. Kombucha is also high in vitamin C, which helps support a healthy immune system.
Grapefruit juice is full of vitamins and minerals. Grapefruit juice:
- Contains vitamin C, which helps strengthen your immune system
- Can help keep you hydrated
- Has antioxidants that help protect the cells in your body
- May help reduce cholesterol levels and is good for your heart
- May help reduce kidney stones
Grapefruits contain substances that interfere with the body’s ability to absorb some medications. Check with your doctor to make sure you can safely consume grapefruit juice.
Salt is a necessary part of a healthy diet. Salt helps balance plasma in your blood and keeps nerves and cells healthy. The World Health Organization recommends that adults limit salt intake to just under one teaspoon per day. Salt also helps maintain the correct balance of minerals and water in your body.
How to Choose a Grapefruit
Grapefruits come in many varieties, from white to pink and red. Most supermarkets have a small selection of ruby red or pink, but depending on your location, you may be able to find more varieties in-store.
When choosing a grapefruit, look for fruit that:
- is plump and heavy
- has fairly smooth skin
- easily bounces back after you squeeze it gently

Pink grapefruit is best for juicing, but you can also experiment with other varieties.
- Red grapefruits are easily available but more bitter than pink grapefruits. It will make your kombucha juice extra tart.
- Melogold grapefruits are hard to find but sweet with few seeds. They have pale green or bright lime-colored skin with yellow flesh.
- White and yellow grapefruits are very tart but juice well. If you choose this variety, you may prefer to add some sugar to your kombucha juice.
How Much Caffeine Is In Salted Grapefruit Kombucha Juice?
Salted grapefruit kombucha juice contains about 7 mg of caffeine per serving if made with black tea kombucha. If you make the recipe with green tea or white tea kombucha, it will contain less than 3 mg of caffeine per serving.
The caffeine in tea helps the SCOBY to ferment correctly, filling your kombucha with healthy probiotics and enzymes.
How Many Calories Are In Salted Grapefruit Kombucha Juice?
Salted grapefruit kombucha contains approximately 60 calories per serving. Since kombucha is low in calories, most calories come from grapefruit juice. Calculating the exact number of calories is difficult since each batch of kombucha and grapefruit is slightly different.
Should You Make This Recipe with Young, Sweet Kombucha or Older, Sour Kombucha?
Make this recipe with young, sweet kombucha. The sweetness of young kombucha will help balance the tartness of the grapefruit juice. It won’t have as much carbonation as an older kombucha but will provide a little fizz.
Use your older, sour kombucha as a starter tea for your next batch of kombucha.
