Green tea is known for being packed with antioxidants, but oolong tea has its own set of health benefits! Both of these teas also have their own unique flavors: green tea is sweet, earthy, and a little grassy, where oolong often has more depth of flavor, depending on what it's blended with and where it's grown. Oolong has historically had flavors more characteristic of black teas, but with shorter oxidation time can take on more green tea flavors.
