Remedy Kombucha Lemonade is an alcohol-free kombucha from Australian brand Remedy, and one of its newer flavours. Kombucha is a fermented tea, and this one is aged for 30 days and kept live cultured, so the active cultures stay in the bottle. Each serving has less than 10mg of caffeine. It tastes like old-school lemonade, tangy with a bit of bite, and has a zesty aroma.
