Four Season Yushan Gaba Oolong 2026

An excellent and delicate, hand-picked and traditionally processed high-mountain GABA oolong from the Four Season cultivar - Si Ji Chun (“Four Seasons”).

The tea leaves grew on the slopes of the Yushan range (also known as “Jade Mountain”) in the Xin Yi area (Taiwan) at an altitude of 1,200 to 1,300 metres, in the shadow of the island’s highest peak, which rises to almost 4,000 metres above sea level. In the taste you can detect notes of fruit, dried apples and pears, caramel, cane sugar, cream and raisins. With each infusion the taste becomes fuller and more pronounced, and the colour of the tea gradually develops to a honey-gold, typical of quality high-mountain oolongs. GABA oolong tea is known for its beneficial effects on health; it contains an exceptionally high amount of antioxidants such as catechins, flavonoids and polyphenols. These substances protect cells from oxidative stress, support immunity and can reduce the risk of lifestyle diseases. GABA oolong is created by oxidation in a nitrogen atmosphere, which increases the GABA content in the tea. To be labelled “GABA”, a tea must, according to international standards, contain at least 150 mg of GABA per 100 g of dry tea; in practice the values most often range between 150-450 mg/100 g. GABA also significantly affects sleep quality - it shortens the time needed to fall asleep, promotes deeper sleep and improves the overall sleep cycle. In addition, it helps reduce stress and anxiety by regulating the levels of stress hormones such as cortisol and stabilising the emotional state. GABA also has a positive effect on cognitive function, supports memory and concentration, and can stimulate the release of growth hormone, which is important for muscle recovery and growth.
