Tea Crush produces sparkling tea tonics in Northern California. Their founder Rosa Li grew up in China drinking her grandmother's immunity-boosting herbal tonics. Inspired by these tonics, Rosa later began exploring plants, medicinal herbs, and rare spices from around the world. Rosa launched Tea Crush in 2017 to share the health benefits of these tonics with more people. All of Tea Crush's tea tonics are USDA certified organic, GMO-free, and gluten-free. Each bottle contains only 5g of sugar from real fruit juice, with no added sugars or sweeteners of any kind.
