Loose leaf green tea (Chá Verde). The Portuguese Hysson green tea is produced using the top three leaves of the Camellia Sinensis plant which are harvested in July and August when the sun is strong. This results in a brownish-green tea with a delicate aroma and intense flavor. It is suitable to be enjoyed at any time of the day and is known for its high levels of tannins and antioxidants, which offer various health benefits. This tea is unique to the region of Azores and is highly valued for its unique flavor, which is a result of the volcanic soil and the mild climate of the region. Chá Gorreana is a brand of tea that is grown and produced on the island of São Miguel in the Azores, Portugal.
