Tea vs. Coffee Quiz - 5 Quiz Challenges for you

There are two main breakfast drinks around the world: tea and coffee. Do you know how they compare? Try out this quick little quiz and see what you know when it comes to comparing these two perennial morning favorites.

1. Which is Older?

Tea is undoubtedly the elder of the two beverages. Indeed, tea is thought to be even older than wine! Tea has been accompanying meals for almost 5,000 years, which is most of humanity’s documented history.

Coffee, on the other hand, only entered the arena in the 11th century at the earliest. Its use was high in the Middle East for some time before entering the western world in the 1700s. Coffee’s actual discovery is still left open to interpretation since no one is quite sure how it came to be used by humans.

Both drinks are venerable, but when it comes to history, there are few drinks that can compete with tea. Depending on who you ask, tea may even be older than beer, which is most often considered the oldest manufactured drink!

2. Which Has More Caffeine?

Tea loses out in this category, having only 45–70 mg of caffeine per cup. Black teas can reach the upper end of this scale and even be comparable to a weak cup of coffee, however.

On the other hand, black coffee contains 95–200 mg of caffeine per cup. By volume, it clearly has more of the good stuff, but there’s a little bit more to the picture here. Both contain a lot more than caffeine, but tea has some very interesting compounds to accompany your caffeine fix.

Tea is less likely to make you jittery since it contains a compound called L-theanine, which balances caffeine while providing a bit of an extra boost. So it comes out to a net draw if you’re looking to boost energy levels.

Those with anxiety should give tea a shot over coffee if they’re not willing to kick their caffeine habit. L-Theanine is actually an anxiolytic, helping to calm a person down. That’s why the energetic buzz from tea is much more subtle and calm!

3. Which is Healthier?

Both drinks have some healthy qualities.

Tea is a known source of antioxidants, which help prevent damage to your DNA from agents called free radicals. The profile of chemicals in green tea, for instance, just seems to make you overall healthier.

Less inflammation, less heart disease, antiviral, and even neuroprotective properties are all found in the tea leaf.

Meanwhile, coffee also has a great reputation for being healthy. A meta-analysis shows lower mortality for all causes across the board. It also showed some minor harmful effects, but they seemed to even out once the study took smoking into account.

Coffee’s health benefits are far more controversial, however. Studies are conflicting and ongoing.

We’re going to have to give this one to tea. While coffee may have some great health effects, tea has a more stable relationship with studies, and the polyphenol compounds within it are all healthy stuff on their own.

4. Which is Better for Weight Loss?

Caffeine is known to increase the metabolism of those who drink it. Unfortunately, the effects taper off as your tolerance to the compound increases.

Coffee’s weight-loss effects are primarily derived from its caffeine content. The effect is, therefore, short-lived, and using coffee to promote weight loss requires cycling it in and out.

Tea, on the other hand, seems to have a lasting effect on the metabolism, which is sustained despite daily tea drinking. It may also come from the fact that tea drinkers tend to abstain from sugary drinks during the day, but many people drink their tea sweetened.

Neither is a magic bullet, and both can help, but tea seems to be the better of the two for those who are looking for a smaller waist.

5. Which is More Widely Consumed?

Those who live in the Western world might assume that coffee is the drink of choice around the world. That’s certainly not the case, but which is more widely consumed?

Tea, by a good margin. The per capita consumption of tea is second only to bottled water in the beverage industry. It’s simply the most widely consumed flavored drink around!

Actually, coffee has some competition here as well. Coffee is actually behind carbonated drinks like Coca-Cola when it comes to worldwide consumption. The impression an American might get that everyone drinks coffee is just wrong; when it comes to worldwide popularity, nothing beats tea!

How’d You Score?

There are some surprises when we compare tea and coffee, in both their histories and their inherent physical qualities. Neither is a bad choice for the morning, but in the end, it appears that tea simply wins out in most categories. How did you score on this short quiz?

FAQs about Tea vs Coffee Comparisons

Which has more caffeine, tea or coffee?

Coffee, by a clear margin. A standard 8oz cup of brewed coffee has 95-120 mg of caffeine. A cup of standard sencha has 25-35 mg. Matcha is in the middle (60-80 mg per bowl) — between sencha and coffee. So drinking the same number of cups, coffee delivers 3-4x more caffeine than tea.

This is partly counter-intuitive because dry coffee beans actually contain less caffeine by weight than tea leaves do. The difference is that coffee uses more dry product per cup (about 10g) compared to tea (about 2-3g for steeped, 2g for matcha) — plus brewing methods extract caffeine differently.

Practical: if you're managing daily caffeine intake, account for what you're actually drinking. Three cups of green tea + one cup of coffee is about 200 mg total caffeine, which is moderate. Three cups of coffee alone is 300+ mg, which is more concentrated.

Which has more antioxidants, green tea or coffee?

Roughly comparable per cup. Green tea provides 50-150 mg of catechins per 8oz cup; coffee provides 70-200 mg of chlorogenic acids per 8oz cup. Both are antioxidant-rich; the specific compound profiles differ. The matcha (抹茶) delivers more total antioxidants per cup than steeped tea or coffee because you ingest the whole leaf.

On total antioxidant capacity (ORAC) measures, coffee usually scores slightly higher per ml. On EGCG specifically (the most-studied tea catechin for cancer-prevention research), green tea wins easily because coffee has essentially no EGCG.

Practically, the difference between green tea and coffee on antioxidants is smaller than the difference between drinking either one and drinking neither. Both contribute meaningfully to total daily polyphenol intake; both stack with antioxidants from food for cumulative benefit.

Which is better for sleep — tea or coffee?

Tea, by a clear margin. The lower caffeine content alone makes tea less sleep-disruptive than coffee. Beyond that, the L-theanine in green tea modulates the caffeine effect to be smoother and gentler — less acute stimulation that can interfere with sleep onset.

For evening drinking specifically, hojicha (ほうじ茶) with its very low caffeine (7-10 mg per cup) is essentially sleep-safe — you can drink hojicha 2 hours before bed without disrupting sleep for most people. Coffee at the same time would be a clear sleep disruptor.

Decaf coffee exists but isn't quite a green-tea equivalent. Removing caffeine from coffee reduces the alertness without adding the calm-focus mechanism that L-theanine provides. So decaf coffee has less sleep impact than regular coffee but doesn't replicate green tea's specifically calming profile.

Which is better for cognitive performance — tea or coffee?

Different rather than better. Coffee provides sharper acute alertness — best for short, intense cognitive tasks. Green tea (especially matcha) provides flatter, longer-duration focus — better for sustained cognitive work over hours.

For peak performance on a 1-hour test or presentation, coffee may have the edge. For 4-8 hours of focused study, writing, or research, tea's sustained-focus profile usually produces better cumulative output. Many committed cognitive workers maintain both — coffee for high-output bursts, tea for deep work blocks.

Both produce real cognitive enhancement compared to no caffeine. The mistake is treating them as competing — they serve different roles. Match the beverage to the work pattern.

Can I just drink both tea and coffee daily without problems?

Easily, with caffeine awareness. Most committed tea-and-coffee drinkers consume both daily — coffee for one part of the day (often morning), tea for another (often afternoon and evening). The total caffeine should be considered (a typical pattern is 1-2 cups of coffee + 3-4 cups of tea daily, totaling around 300-400 mg caffeine), but the combination is normal for many adults.

Watch for: caffeine sensitivity (jitters, anxiety, sleep issues), iron-absorption interference if you have iron-status concerns, gastric discomfort from drinking both daily on a sensitive stomach. If any of these emerge, reduce one or the other.

My typical day: coffee in the morning (alertness boost, social ritual), sencha mid-morning (sustained focus), gyokuro or matcha early afternoon (umami pleasure), hojicha in the evening (low-caffeine wind-down). The two beverages serve different roles in different windows; both are present without conflict.
