Immerse your senses like never before with our selection of hand-picked, natural Oolong teas and blends. When it comes to tea, a true connoisseur knows the term “oxidation” is crucial. Tea masters carefully watch over the production process, creating lighter oolongs with less oxidation and darker oolongs that are more thoroughly oxidized - the oxidation can vary from 20% to 80%. Oolong Tea contains about 25% as much caffeine as one cup of coffee.
