Matcha maker, matcha maker, make me a March matcha latte, please. Bantam + Biddy Crescent Avenue and Lenox Square locations are crafting matcha lattes this month to celebrate St. Patrick’s Day. Matcha, a powdered green tea that is shade grown, is a naturally sweet superfood rich in antioxidants. Its caffeine level parallels that of coffee but without the post-cup crash. Bantam + Biddy uses Rishi tea in its lattes, which can be enjoyed hot or iced with your choice of milk.
