4,000 Years of Being Taken Seriously — and For Good Reason
Green tea is one of the oldest deliberately cultivated drinks on earth. First recorded in China around 2737 BCE, it has been the daily drink of choice for vast populations across East Asia not simply because of its flavour, but because of how it makes people feel — alert but calm, focused but not anxious, energised without a subsequent crash.
That experience has a specific chemical explanation, and it sets green tea apart from every other hot drink you can order at Tea Oasis. Understanding it makes the choice to order it a more informed one.
The Science Behind the Feeling — EGCG and L-Theanine
Green tea contains two compounds that work together in a way no other common beverage replicates:
- EGCG (epigallocatechin gallate): the most abundant and studied antioxidant in green tea, associated with cardiovascular health, metabolic support, and cellular protection from oxidative stress. Research has consistently identified green tea as one of the richest dietary sources of polyphenol antioxidants of any food studied
- L-theanine: an amino acid found almost exclusively in tea — and in higher concentrations in green tea than in black tea. L-theanine promotes alpha brain wave activity, the state associated with alert, relaxed focus. Combined with caffeine (present in green tea at lower levels than coffee or black tea), it creates what researchers describe as ‘alert calmness’ — energy without jitteriness
This combination is why green tea produces a different subjective experience from coffee. Coffee’s caffeine creates a sharper, more immediate energy that also produces more pronounced peaks and crashes. Green tea’s caffeine, modulated by L-theanine, produces a gentler, more sustained focus without the anxiety or subsequent energy drop many people associate with coffee.
Plain Green Tea vs. Green Tea with Mint
Both are available at Tea Oasis, and the choice is more than a matter of taste:
- Plain green tea: the clearest way to taste the tea itself — its natural vegetal, slightly sweet, subtly grassy character. The flavour varies considerably with temperature and steeping time. This is the purist version
- Green tea with mint: a Middle Eastern food culture tradition, where fresh mint is paired with green tea to add brightness and digestive benefit. Mint’s natural menthol compounds complement green tea’s gentle bitterness, and the combination has been served across the Arab world and North Africa for generations. It’s a culturally rooted pairing, not a flavour novelty
If you’ve found green tea bland in the past, the mint version frequently changes that perception entirely.
Why Temperature and Steeping Matter
The single most common reason people find green tea bitter or unpleasant is incorrect preparation — specifically, water that’s too hot or tea that’s steeped for too long. Green tea, unlike black tea or karak, is sensitive to temperature: boiling water destroys some of its delicate compounds and produces excessive bitterness from the tannins. Proper green tea is brewed with water around 70-80°C, for 2-3 minutes — not boiling, and not long.
At Tea Oasis, we brew green tea at the correct temperature, steeped for the right amount of time. The result is a clean, balanced cup without the bitterness that puts people off the drink in the first place.
When to Choose Green Tea
- Mid-morning or afternoon: when you want focus without a strong caffeine effect — green tea’s L-theanine creates calm clarity that suits working or studying
- After a sweet chapati: green tea’s light bitterness and clean character acts as a palate refresher after something rich or sweet — particularly effective with honey, lotus, or hazelnut cream chapati
- When you’re watching caffeine intake: green tea has roughly one-third the caffeine of coffee, making it suitable for those monitoring their daily caffeine while still wanting a warm, energising drink
