What I really want to do here is post as much for my own reference as for any, what ingredients I put in my Go To Kombucha.
6 oz kombucha (which I make with 2/3 green tea and 1/2 black)
6 oz guava tea (cold pressed ie a bag left overnight in fridge in a glass of water)
A huge glass of ice
1 to 2 TBS Cherry Torani syrup (or coconut or blood orange or any other flavor/s)
If I have sweet oranges on my tree their juice substitutes for some or all of the syrup depending on how long the booch has been fermenting. My oranges are still green at present so I am glad to use the Torani, which contains real sugar, not corn syrup (bleagh). Torani has about 12 grams of sugar in one tablespoon which is 1/2 ounce of syrup. The pictured glass holds my beverage plus 2 cups of ice, and so the drink pictured is about 45 calories.
