Of the plain and flavored kombuchas that One Lucky Duck makes in-house, the best is their Passionfruit Kombucha ($7/bottle).
Both tart and rounded, One Lucky Duck's version is significantly less fizzy than Brooklyn Kombucha and the popular GT's Kombucha. Here the kombucha culture is coupled with organic black Darjeeling tea for a subtle, light note of smokiness. The passionfruit puree shines though confidently and there is just a touch of agave for sweetness. Though it's nearly twice the price of other brands, it's kombucha worth the indulgence.
