Tea BIOSHAN Dairy oolong wholesale. Weight: 80 g. Minimum order 89 pcs. One of the most popular types of tea in recent years. Oolong tea is a special kind of tea that takes pride of place between green and black teas. It is produced in such a way that only the edges of the tea leaf are fermented, so oolong tea combines the noble aroma of green tea and the rich taste of black tea. A milky-creamy aftertaste adds new emotions from tea drinking.
