It is a tea leaf made from 100% olive leaves produced in Yanagawa City, Fukuoka Prefecture and Wamizu Town, Kumamoto Prefecture. The leaves were carefully removed one by one from the pruned branches by hand, steamed and processed into tea leaves. It can only be produced during the spring pruning period every year, and it is necessary to process it while maintaining its freshness, and mass production is not possible, so the annual shipment volume is negligible. Thank you for your understanding. Like other flavors, this product is caffeine-free and can be enjoyed by anyone without worry. The refreshing taste like herbal tea and the sparkling golden brown tea will create a special time. A gem that you can enjoy during relaxation time or before going to bed. It is also useful in hospitality.
