Our signature brew, Lemongrass Kombucha, is fermented with lemongrass instead of tea, which makes it naturally caffeine-free. It's the most thirst-quenching and hydrating kombucha ever brewed, with fruity citrus notes and floral sweetness. Our organic lemongrass is sourced from Egypt, which delivers earthy and floral notes. At Shen Zen Tea, we do more than just flavor kombucha, we create new cultures. Our Lemongrass Kombucha Culture was selectively grown by our Master Brewer and owner, James F. Chang, based on insights from peer reviewed scientific articles regarding optimal ways to brew kombucha for health benefits. Much like tea, lemongrass is a strong pre-biotic, which helps probiotics flourish.
