Remove the leaves from one sprig of rosemary and chop very finely. Combine with sugar and transfer to a small plate or dish that is larger than the diameter of the glasses you will be using. Rub the edge of each glass with lemon, then invert the glass into the rosemary-sugar mixture to rim the glasses.
Combine pineapple juice, lemon juice and maple syrup in a pitcher. Stir to combine, as the maple syrup will sink to the bottom. Slowly add the kombucha.
Pour over ice-filled, rosemary-rimmed glasses and garnish with lemon slices and sprigs of fresh rosemary. Serve immediately.
Kombucha tends to cut the sweetness in a drink, so you may want to adjust the amount of maple syrup to suit your taste. Different brands of kombucha will also vary in sweetness, so play around with this drink to find the balance you like best.Calorie count does not include alcohol.
