Studies have shown that consuming tea regularly can improve health. However, steeping tea leaves in hot water doesn’t necessarily give you the full breadth of antioxidants and nutrients found in tea. When you grind the leaves to a powder, you enhance the flavor and release the powerful nutrition of tea. Kyocera’s advanced ceramic millstones will grind whole leaves from a coarse to a fine powder, giving you optimal nutritional intake, flavor, and convenience. We recommend buying high-quality tea and herb leaves for best results.
