GABA Tea Tasting Night
不時會有茶友問：「GABA 到底是甚麼茶？」
GABA（γ-胺基丁酸）是胺基酸的一種，茶葉本身便含有少量 GABA。
所謂 GABA 茶，是在製作過程中經過缺氧處理，促使 GABA 大量累積。因此，GABA 茶並非特定的茶類；綠茶、烏龍茶、紅茶等，都可以製成 GABA 茶。一般來說，每100g 乾茶的 GABA 含量需達到150 mg 或以上，才會被稱為 GABA 茶。
GABA 是人體重要的抑制性神經傳導物質，參與調節神經興奮，與放鬆、壓力調節及血壓調控等生理作用有關。不過，現有研究認為，口服 GABA 難以通過血腦屏障，因此未必能直接進入大腦並發揮作用。部分研究提出，攝取的 GABA 可能透過腸道中的 GABA 受體、腸腦軸及周邊神經系統間接產生影響；亦有研究觀察到，攝取 GABA 後，參與者的壓力及焦慮相關指標有所改善，但其實際作用機制與效果仍未有定論。
即使如此，撇開 GABA 的實際生理作用，不同茶類、不同品種，以 GABA 製程製作後，會呈現怎樣不同的香氣、滋味與口感？
9月19日的晚上，我將準備 6–7 款不同的 GABA 茶，涵蓋不同茶類、品種與品質，以評茶及茶藝兩種方式沖泡，一起品飲和記錄，交流彼此的感受與喜好。
What exactly is GABA tea?
GABA (γ-aminobutyric acid) is an amino acid naturally found in tea leaves. Through oxygen-free processing, GABA levels increase significantly. GABA tea is not a specific tea category — green, oolong and black teas can all be made into GABA tea.
GABA is an inhibitory neurotransmitter associated with relaxation, stress regulation and blood pressure. While oral GABA does not readily cross the blood-brain barrier, some studies suggest possible effects through the gut-brain axis and peripheral nervous system.
Its exact mechanisms, however, remain inconclusive.
Beyond its potential physiological effects, how different can GABA teas actually taste?
On September 19, we’ll taste 6–7 GABA teas across different tea types, cultivars and quality levels, using both comparative evaluation and traditional brewing methods.
Taste, compare, take notes, and share what we find in the cup.
