The word “caffeine-free” appears on tea menus and packaging across the hospitality industry — yet in most cases, no one has defined what it actually means. Is a tea with 3mg of caffeine per cup caffeine-free? Does “low caffeine” mean less than coffee, or something more precise?
Without a clear standard, these terms are marketing language, not useful information.
At TeaTach, every tea in our range is classified using a single consistent method: milligrams of caffeine per 100ml of brewed tea, measured under our standard brewing parameters for each product.
Why per 100ml?
Caffeine content is most meaningfully expressed per volume of beverage — the same unit used in food science and beverage regulation. Per-cup figures vary with cup size. Per-gram-of-leaf figures don’t reflect how much caffeine actually ends up in the drink. Per 100ml of brewed beverage is the only measurement that allows consistent, fair comparison across different tea types and preparation methods.
The Three Tiers
Caffeine Free — ≤ 2 mg / 100ml
No meaningful caffeine. The 2mg ceiling, rather than absolute zero, accounts for trace-level variation in natural plant material and measurement. Any tea in this category produces no physiological caffeine effect.
Low Caffeine — ≤ 10 mg / 100ml
Minimal caffeine — a small fraction of what is found in coffee or standard black tea. Suitable for guests who wish to reduce but not eliminate caffeine.
High Caffeine — above 10 mg / 100ml
A meaningful caffeine level. Teas in this category should be treated as caffeinated beverages when advising guests.
A Note on Brewing
All classifications are based on our recommended brewing ratio and temperature for each product. Caffeine extraction increases with higher water temperature, longer steeping time, and greater leaf-to-water ratio. For the caffeine content to match our classification, follow the recommended parameters.
Why This Matters for UAE Cafe Menus
The UAE has a higher proportion of caffeine-aware customers than most other hospitality markets. A significant share of the population avoids caffeine entirely for religious or health reasons. A growing segment — particularly among international expats — tracks caffeine intake deliberately for wellness reasons. And a standard customer base of health-conscious urban professionals increasingly asks about what is in their drinks.
For a cafe or restaurant, this means caffeine classification is not just a labelling exercise. It is a service decision. Knowing whether chamomile is genuinely caffeine-free (it is), whether jasmine green tea contains caffeine (it does), and what threshold separates low caffeine from caffeine-free in practical terms allows your team to answer questions accurately — and build guest trust in the process.
How to Apply the Classification on Your Menu
The classification system works best when it is visible, not buried. A simple label alongside each tea — caffeine-free, low caffeine or high caffeine — gives guests the information they need to choose without having to ask. For evening service, this is especially important: a guest managing their sleep should see at a glance which drinks are safe for them.
Consider grouping caffeine-free options together in one clearly labelled section of your tea menu. In hotel and spa settings, a separate Caffeine-Free Choices section has consistently increased herbal and botanical tea orders during evening service.
For staff, the classification standard also simplifies training. Rather than memorising every individual product, your team learns three clear tiers — and can make accurate recommendations based on what a guest tells them about their caffeine needs. A server who can say "that one is genuinely caffeine-free, this one has about the same caffeine as green tea" is providing real service value.
This standard applies to every product in the TeaTach range.
