The Pu erh red tea from Cafés Guilis is an exquisite fermented tea that has matured in barrels for fifteen years. Also known as Pu Erh tea, its name comes from the Pu-Erh region in Yunnan, China, and it is famous for its earthy and intense flavor. This type of tea is not only delicious but is also recognized for its health benefits, aiding digestion and supporting weight loss. Its caffeine content is medium, higher than green tea but less than black tea. For the best flavor, it is recommended to steep at 95º C for 4 minutes, using 3 grams of tea for every 300 ml of water.
