GABA Oolong vs Oriental Beauty

GABA Oolong

GABA oolong is processed in a nitrogen-rich environment that converts glutamate into gamma-aminobutyric acid, giving the tea a distinctive tangy-sweet profile. The cup is smooth and fruity — often compared to sour plum or dried apricot — with a thick, cooling body and a long, clean finish. It is typically made from mid-oxidation Taiwanese leaf and is popular as an evening tea.

Oriental Beauty

Oriental Beauty is a heavily oxidized Taiwanese oolong whose honeyed sweetness comes from leafhoppers nibbling the leaves before harvest. The cup is rich and aromatic: ripe honey, muscat grape, and a warm spice undertone with a smooth, cooling finish. It is one of the most distinctive oolongs and often surprises drinkers expecting something floral.
