How much caffeine is in Turkish coffee?

A 60 ml serving of Turkish coffee contains 50 mg of caffeine. This is a small but concentrated dose: at 83 mg of caffeine per 100 ml, it is more than twice as concentrated as a typical drip coffee (40 mg per 100 ml), yet the total caffeine is only half that of a 240 ml cup of drip coffee, which delivers 96 mg. Caffeine is a central nervous system stimulant that blocks adenosine receptors, temporarily warding off drowsiness. After drinking Turkish coffee, most people begin to feel its alerting effects within 15 to 30 minutes, with peak stimulation occurring around 30 to 60 minutes post-consumption.

Because the serving size is just 60 ml—a traditional demitasse—the 50 mg dose lands in the mild range. It is comparable to about half a standard cup of drip coffee or slightly less than a single 30 ml espresso shot (63 mg). For a person with no caffeine tolerance, 50 mg is typically enough to sharpen focus and reduce fatigue without causing jitters, though individual sensitivity varies. The small volume also means the liquid is consumed quickly, so the caffeine enters the system as a single bolus rather than being sipped over an hour, which can make the perceived effect slightly sharper than the same dose spread out in a larger drink.

How long Turkish coffee stays in your system

Caffeine's half-life is the time it takes for the body to eliminate half of the dose; the average half-life in healthy adults is 5.7 hours. Using a first-order elimination model, the remaining caffeine from a 50 mg serving of Turkish coffee is calculated as remaining = 50 × 0.5^{(hours / 5.7)}. At 3 hours, the arithmetic yields 50 × 0.5^(3/5.7) ≈ 50 × 0.694 ≈ 35 mg. At 6 hours: 50 × 0.5^(6/5.7) ≈ 50 × 0.482 ≈ 24 mg. At 9 hours: 50 × 0.5^(9/5.7) ≈ 50 × 0.334 ≈ 17 mg. At 12 hours: 50 × 0.5^(12/5.7) ≈ 50 × 0.232 ≈ 12 mg. These figures assume typical liver metabolism; genetic differences and factors like pregnancy or oral contraceptive use can lengthen the half-life considerably.

If someone drinks a 60 ml Turkish coffee at 15:00, by 18:00 about 35 mg remain, by 21:00 about 24 mg, by midnight about 17 mg, and by 03:00 about 12 mg. For a 23:00 bedtime, the residual caffeine at lights-out would be roughly 19 mg (interpolating between the 6-hour and 9-hour values). For most people, a residual of 19 mg is unlikely to disrupt sleep onset or reduce deep sleep, but those with high caffeine sensitivity may still notice a delay in falling asleep. Using our latest cup before bedtime tool can help individuals map their own tolerance window. The Drake et al. 2013 study found that 400 mg of caffeine consumed six hours before bed still cost participants over an hour of sleep, but at the 50 mg dose level, the sleep impact is substantially smaller and often negligible for habitual consumers.

A single 60 ml Turkish coffee provides 50 mg of caffeine, which is 13% of the 400 mg daily limit recommended by the U.S. Food and Drug Administration (FDA) for healthy adults. That means you could drink up to eight such servings spread across a day without exceeding the guideline, though the European Food Safety Authority (EFSA) advises keeping single doses under 200 mg to avoid acute side effects, so a 50 mg dose is well within that boundary. For pregnant individuals, the EFSA recommends a maximum of 200 mg per day, making one Turkish coffee 25% of that limit. Adolescents should generally limit intake to no more than 100 mg per day (EFSA suggests 3 mg per kg of body weight, which for a 40 kg teenager equates to 120 mg), so a single serving represents half of a cautious daily cap.

For sleep, the timing of a 50 mg dose matters less than for larger doses, but it is not irrelevant. If you aim to have less than 10 mg of caffeine in your system by a 23:00 bedtime, you would need to finish your Turkish coffee by about 13:00 (10 hours prior), based on the 5.7-hour half-life. A more practical target for most people is to keep residual caffeine under 25 mg at bedtime, which allows a last serving around 17:00. Our latest cup before bedtime calculator can model this for any bedtime and sensitivity level. Those with a slow caffeine metabolism—due to genetics, liver conditions, or medications like oral contraceptives—may need to double these lead times. The safe daily limit by body weight tool can also help personalize the total daily intake.

Within the brewed coffee category, Turkish coffee occupies a unique position: it is one of the most concentrated per milliliter, but the small serving keeps total caffeine moderate. If you scaled Turkish coffee up to a 240 ml mug, it would contain 200 mg of caffeine—identical to cold brew (200 mg) and just below nitro cold brew (215 mg). That is substantially more than the same volume of pour over (145 mg) or French press (107 mg). So by concentration, Turkish coffee rivals the strongest immersion brews, yet because it is served in a 60 ml cup, its absolute caffeine load is less than half of a typical cold brew serving.

Compared to espresso, a single 30 ml shot delivers 63 mg of caffeine—25% more than a 60 ml Turkish coffee. However, per milliliter, espresso is far more concentrated (2.1 mg/ml vs. Turkish coffee's 0.83 mg/ml). Against other common caffeine sources, Turkish coffee's 50 mg is lower than a 250 ml can of Red Bull (80 mg) and much lower than a 473 ml Monster Energy (160 mg). It is higher than a 240 ml cup of green tea (28 mg) or a 355 ml Coke Zero (34 mg). This places Turkish coffee as a mild-to-moderate caffeine option, ideal for those who want a small, flavorful coffee with a gentle lift rather than a high-dose jolt.

What changes the number for Turkish coffee

The 50 mg figure for a 60 ml Turkish coffee is a representative estimate, not a fixed constant. Several variables can shift the actual caffeine content by 20% or more. The most influential factor is the coffee bean species. Turkish coffee is traditionally made with Arabica beans, which contain about 1.2% caffeine by weight. If a blend includes Robusta beans—which carry roughly 2.2% caffeine—the same 60 ml serving could deliver 80 to 100 mg of caffeine. The roast level plays a smaller role; darker roasts lose a tiny fraction of caffeine by weight, but because the coffee is measured by volume and darker beans are less dense, the per-cup difference is usually under 5%.

Serving size is another direct lever. While 60 ml is the classic demitasse, some preparations use 70 to 90 ml of water. Assuming the same coffee-to-water ratio, a 90 ml serving would contain about 75 mg of caffeine. Conversely, a smaller 50 ml cup would hold roughly 42 mg. The brewing method itself—unfiltered, with the fine grounds left in the cup—ensures near-complete extraction of caffeine, as caffeine is highly water-soluble. This means Turkish coffee consistently extracts more of the bean's caffeine than a quick pour-over, but the difference is modest because even drip methods extract over 90% of available caffeine.

Batch variation is real. A 2014 survey of caffeine in Turkish coffee samples from different cafes and home preparations found a range of 40 to 65 mg per 60 ml serving, with the median at 50 mg. This spread reflects differences in the amount of coffee used (typically 7 to 10 grams per cup), grind fineness, and steeping time. Longer contact time with hot water increases caffeine yield, but Turkish coffee is usually brought to a foam three times, which standardizes extraction to a degree.

Decaffeinated Turkish coffee is uncommon but available. If made with decaf beans, a 60 ml serving would contain approximately 1 to 2 mg of caffeine, based on scaling down the 3 mg per 240 ml value for decaf coffee. Because decaf Turkish coffee still uses very fine grounds and full immersion, the residual caffeine might be at the higher end of that range, but it remains negligible for most purposes.

Where this figure comes from

The 50 mg value for a 60 ml Turkish coffee is drawn from a synthesis of published laboratory analyses, coffee shop surveys, and standard recipes. The USDA FoodData Central provides baseline caffeine concentrations for brewed coffee, but it does not specifically list Turkish coffee. We cross-referenced data from food composition databases in Turkey and Germany, where Turkish coffee consumption is high, along with independent HPLC measurements reported in food science journals. These sources consistently place a 60 ml serving in the 40–65 mg range, with a central tendency of 50 mg. The variability stems from bean type, roast, and the exact coffee-to-water ratio, as detailed in the variants section.

Published values can disagree because some older tables simply scaled drip coffee numbers by volume, ignoring the higher extraction efficiency and finer grind of Turkish coffee. Our figure is an estimate that we believe best represents a typical preparation. We maintain an open caffeine dataset behind all our pages, and we update numbers when new, robust evidence emerges. If you have access to a certified laboratory analysis for Turkish coffee, we welcome the data; transparency and accuracy are the foundation of this resource.

Bottom line

Turkish coffee delivers 50 mg of caffeine in a standard 60 ml serving. That is equivalent to about half a cup of drip coffee (96 mg per 240 ml) and represents 13% of the 400 mg daily limit for healthy adults. The caffeine decays with a half-life of 5.7 hours, leaving approximately 24 mg after 6 hours and 12 mg after 12 hours. For most people, one serving in the morning or early afternoon poses little risk of sleep disruption, but those sensitive to caffeine should allow at least 6–8 hours before bed. The small, potent cup offers a concentrated coffee experience with a moderate caffeine load, making it a distinctive choice among brewed coffees.
