The BREWT™ Infuser is a revolutionary method for making your favourite fine tea. The BREWT™ lets you brew a perfect cup of loose tea with no mess. It is ideal for the home, the office, school, and in restaurants. Its design is elegantly simple. The unique and patented shut-off valve keeps the liquid in the BREWT™ until your tea is brewed perfectly to your taste. When you place it on your cup, the weight opens the valve and the infused tea flows through the specially designed filtration system. When you lift the BREWT™ from your cup, the valve automatically closes again, to keep the leaves and any remaining liquid in the infuser. The is BREWT™ brilliant !
