How much caffeine is in Club-Mate?

Club-Mate (330 ml) contains 66 mg of caffeine (USDA FoodData Central).

Caffeine is a central nervous system stimulant; the concentration here is 20 mg per 100 ml by the same source (USDA FoodData Central), which makes a 330 ml bottle 66 mg in total. Compared with a normal cup of drip coffee (96 mg per 240 ml, reference: Drip coffee entry), this single 330 ml bottle is about 0.7× a 240 ml drip coffee serving (calculation: 66 mg ÷ 96 mg = 0.6875) and therefore produces a smaller, shorter-lived stimulant load than a full cup of drip coffee (Drip coffee reference). The physical feeling from 66 mg is typically mild alerting for people who are not highly sensitive — measurable increase in wakefulness that usually peaks within 30–90 minutes after ingestion and then declines as caffeine is eliminated (population-average kinetics; see halflife and timing below). For side-by-side numeric comparisons, see our internal caffeine comparison tool at /tools/caffeine-comparison/ (internal dataset links inside).

How long Club-Mate stays in your system

A half-life is the time it takes for the amount of a substance in the body to fall by half; for caffeine we use a population-average half-life of 5.7 hours (TrackCaffeine model). Using first-order elimination, the remaining caffeine after t hours is calculated as Remaining = 66 mg × 0.5^(t / 5.7). For common checkpoints the arithmetic is: 3 h → 66 × 0.5^(3/5.7) = 66 × 0.695 ≈ 45.9 mg (≈46 mg); 6 h → 66 × 0.5^(6/5.7) = 66 × 0.482 ≈ 31.8 mg (≈32 mg); 9 h → 66 × 0.5^(9/5.7) = 66 × 0.335 ≈ 22.1 mg (≈22 mg); 12 h → 66 × 0.5^(12/5.7) = 66 × 0.232 ≈ 15.3 mg (≈15 mg) (model: TrackCaffeine half-life = 5.7 h).

If a bottle is finished at 15:00, the model predicts at 23:00 (8 hours later) Remaining = 66 × 0.5^(8/5.7) = 66 × 0.378 ≈ 25.0 mg remaining in the body (TrackCaffeine model); this means measurable central nervous system exposure persists into the evening for a typical adult but is substantially reduced from the original 66 mg.

For personalized timing estimates use the half-life calculator at /tools/caffeine-calculator/ (internal tool); the numeric checkpoints above assume the population average and do not account for age, pregnancy, liver function, drug interactions, or genetic differences that change half-life (caveat: individual half-life may be longer or shorter than 5.7 h).

Sixty-six milligrams is 17% of the 400 mg per-day guidance for healthy adults; that 400 mg guidance is stated by the U.S. Food and Drug Administration (FDA) (FDA, 400 mg/day), so up to five to six similar bottles would exceed that daily guidance if combined with other sources (calculation: 400 mg ÷ 66 mg ≈ 6.06 bottles). The European Food Safety Authority recommends a lower limit for pregnancy (200 mg/day) in its 2015 opinion, so 66 mg would represent about 33% of that pregnancy recommendation (EFSA Scientific Opinion on the Safety of Caffeine, 2015).

Using the first-order elimination model above, if a 330 ml bottle is finished at 15:00 then roughly 25 mg remains at 23:00 (66 × 0.5^(8/5.7) ≈ 25 mg; TrackCaffeine model), which is still measurable and could be relevant to sleep. A randomized controlled study found that 400 mg consumed six hours before bedtime still cost over an hour of sleep on average (Drake et al., 2013); that finding indicates timing matters but does not give a universal safe cutoff for 66 mg, so individuals sensitive to evening caffeine should allow several hours between a bottle and a 23:00 bedtime or use the dedicated calculator at /tools/last-cup-before-bed/ (internal).

Adolescents, pregnant people, and those with known sensitivity to stimulants should use stricter limits: EFSA recommends ≤200 mg/day in pregnancy (EFSA Scientific Opinion, 2015), and many pediatric guidance sources urge lower per-day totals for adolescents (reference: EFSA and public health guidance). For precise weight-based guidance see our tool at /tools/safe-daily-limit/ (internal).

Within the soft-drink category, Club-Mate at 66 mg (dataset, USDA FoodData Central) sits above common colas: Coca-Cola 330 ml contains 32 mg and Coca-Cola 355 ml contains 34 mg (dataset), so one 330 ml Club-Mate has roughly double the caffeine of a 330 ml Coca-Cola by our data. It is lower than many mainstream energy drinks: for example, Red Bull (250 ml) is 80 mg and Monster Energy (473 ml) is 160 mg (reference: Other reference points), so Club-Mate gives more caffeine than cola but less than most branded energy drinks.

Against coffee, a typical 240 ml cup of drip coffee contains 96 mg (Drip coffee entry), so Club-Mate’s 66 mg is about 0.7× that cup (calculation: 66 ÷ 96 ≈ 0.6875) and is very close to a single 30 ml espresso shot at 63 mg in our reference points (espresso single: 63 mg). These direct comparisons use values from our dataset and standard reference points (dataset and coffee reference entries) to show where 66 mg sits on the caffeine spectrum.

What changes the number for Club-Mate

The 66 mg figure is tied to the standard 330 ml serving measured in the open dataset; serving size is the primary factor that moves the absolute caffeine amount (source: USDA FoodData Central and our /dataset/ listing). If you consume a different volume, caffeine scales proportionally: double the volume (660 ml) would double the mg, half the volume would halve it (arithmetic based on 20 mg per 100 ml from the dataset).

Other causes of variation for sodas include formulation differences between product lines and measurement methods; ingredient lists and manufacturer testing can vary by batch and country, and analytical results reported to databases like USDA FoodData Central or manufacturer lab sheets may differ by a few mg. There is no widely distributed “decaf” Club-Mate product documented in the dataset, so the 66 mg value applies to the standard caffeinated recipe (dataset, USDA FoodData Central).

The same-category entries in our dataset show how brand and serving size change caffeine content; the exact comparisons in our data are:

• Coca-Cola (330 ml): 32 mg (dataset).
• Coca-Cola (355 ml): 34 mg (dataset).
• Coca-Cola Diet Coke (355 ml): 46 mg (dataset).
• Coca-Cola Coke Zero (355 ml): 34 mg (dataset).
• Pepsi (355 ml): 38 mg (dataset).
• Diet Pepsi (355 ml): 35 mg (dataset).
• Mountain Dew (355 ml): 54 mg (dataset).
• Dr Pepper (355 ml): 42 mg (dataset).
• Barq's Root Beer (355 ml): 22 mg (dataset).
• Sunkist Orange (355 ml): 41 mg (dataset).

Because of this variability, the single 66 mg number should be treated as the best available standardized estimate for a 330 ml bottle in our dataset and not as a precise constant for every bottle sold worldwide.

Where this figure comes from

The 66 mg caffeine value for Club-Mate in this page comes from entries compiled in the open dataset and from FoodData Central where available (USDA FoodData Central, dataset). Published values differ because laboratories use different analytical methods, product formulations change over time, and manufacturers report results per country or per production run; these causes explain most small disagreements between sources (USDA FoodData Central; manufacturer disclosures when available).

We will update this page if new, higher-quality lab analyses, manufacturer statements, or regulatory updates replace the current dataset value; the open dataset page /dataset/ lists version history and provenance for the entry (internal dataset listing).

Bottom line

Bottom line: a 330 ml bottle of Club-Mate contains 66 mg of caffeine (20 mg per 100 ml) according to our dataset (USDA FoodData Central); that is about 0.7× a 240 ml cup of drip coffee (66 ÷ 96 ≈ 0.69, drip coffee reference) and equals 17% of the FDA 400 mg daily guidance (FDA, 400 mg/day). Using a 5.7 h population half-life model, expected remaining amounts are roughly 46 mg at 3 h, 32 mg at 6 h, 22 mg at 9 h, and 15 mg at 12 h after drinking (TrackCaffeine model arithmetic shown above), so a bottle consumed mid-afternoon still leaves measurable caffeine in the evening.
