Tim Hortons Coffee Caffeine: Size and Drink Breakdown

A medium Tim Hortons Original Blend (295 ml) contains 140 mg of caffeine.

• 140 mg — caffeine in a medium Tim Hortons Original Blend (295 ml).
• 68–200 mg — typical Tim Hortons espresso-based and cold-brew ranges: latte 240 ml = 68 mg; cold brew 240 ml = 200 mg.
• 3 mg — a 240 ml decaf at Tim Hortons, per dataset, contains only 3 mg.
• ~68 mg — after about 6 hours roughly half of 140 mg (~68 mg) remains in the average person (half-life ≈ 5.7 h).

How Tim Hortons compares to other chains

Comparisons use exact dataset values: medium Tim Hortons brewed coffee (295 ml = 140 mg) fits in the mid-range when compared to other chains. Below shows standard servings from the dataset.

Decay over time: how much remains after drinking a medium (140 mg)

Use a population-average half-life of 5.7 hours (caffeine elimination approximated as first-order). Fraction remaining = (1/2)^(t/5.7). For a 140 mg dose these are the expected averages:

Time after dose	Fraction remaining	Approx. caffeine remaining (mg)
0 h	100%	140 mg
3 h	~69.4%	~97 mg
6 h	~48.2%	~68 mg
9 h	~33.4%	~47 mg
12 h	~23.2%	~33 mg

Why the numbers vary: brewing, shots and serving size

Caffeine per cup is a function of concentration (mg/100 ml in the dataset), shot count, and serving volume. Examples from the dataset show wide spread: pour over 240 ml = 145 mg (60.4 mg/100 ml) versus drip 240 ml = 96 mg (40 mg/100 ml) and cold brew 240 ml = 200 mg (83.3 mg/100 ml). Espresso-based drinks vary by shot: a single espresso (30 ml) is 63 mg while a double is 126 mg.

Common variables

• Bean origin and roast — lighter roasts often measure higher caffeine by volume than darker roasts, though bean density matters.
• Brew method — cold-brew and pour-over in the dataset are substantially higher than drip or instant per the same 240 ml standard.
• Shot count and drink size — lattes with one shot (240 ml = 68 mg) versus two-shot large lattes (350 ml = 126 mg).

Decaf, iced drinks and the Iced Capp question

The dataset lists decaf coffee at 240 ml = 3 mg; that’s residual caffeine, not zero. Many iced specialty drinks (Iced Capp is not in the dataset) combine coffee, milk, cream and sugar; caffeine will vary with whether they use instant coffee, espresso shots, or a brewed concentrate. If you need a quick estimate for an Iced Capp, treat it like a 1–2 shot blended drink: expect roughly 60–130 mg depending on shot count — mark that as an estimate unless the chain supplies a specific value.

Health context and timing vs sleep

Authoritative guidance: the FDA notes 400 mg/day as a typical safe upper limit for healthy adults; many organizations advise lower limits in pregnancy (~200 mg/day) and the American Academy of Pediatrics discourages caffeine for adolescents. If you drink a 140 mg medium Tim Hortons in the afternoon, expect roughly 68 mg to remain at 6 hours — which can still affect sleep for sensitive individuals. For personalized tracking and to avoid exceeding daily limits, log drinks in an app such as CoffeeLog to sum milligrams across beverages and snacks.

Bottom line: practical advice

A medium Tim Hortons coffee is 140 mg of caffeine—enough for most adults to feel alert and for some to notice jitteriness. Choose decaf (3 mg per 240 ml in the dataset) or smaller sizes if you need to limit intake; consider brew-method differences if you want higher or lower caffeine. Track totals against FDA and specialty guidance and consult a clinician for pregnancy, pediatric, or medical concerns.
