GABA Taiwan Oolong Premium is a unique Taiwanese oolong made using a special oxygen, free technology that significantly increases the content of gamma-aminobutyric acid (GABA). The taste is rich and deep, with notes of ripe fruits, caramel and light woody sweetness. The aftertaste is long, enveloping, without bitterness. It gently reduces anxiety, improves sleep and helps to recover from stress, thanks to the record GABA content among all types of tea.
