Caffeine in Dunkin lattes by size and common equivalents

Dunkin lists a Medium Latte at 414 ml with 119 mg of caffeine in the provided dataset. Dunkin’s latte caffeine comes from espresso shots; the dataset’s single shot is 63 mg and a double is 126 mg, so shot count drives most variation.

Drink	Serv. size	Caffeine (mg)
Dunkin Latte (Medium)	414 ml	119 mg
Latte (standard)	240 ml	68 mg
Latte (large, 2 shots)	350 ml	126 mg
Espresso (single)	30 ml	63 mg
Espresso (double)	60 ml	126 mg
Dunkin' Original Blend (Medium) — brewed	414 ml	210 mg
Dunkin Cold Brew (Medium)	710 ml	260 mg

Iced latte caffeine: what to expect

Searches for "caffeine in dunkin donuts iced latte" are common; iced and hot lattes at Dunkin typically use the same espresso shots, so caffeine is similar by size. A 414 ml iced Dunkin Latte in the dataset is 119 mg. If you add an extra shot, add ~63 mg per single shot (dataset single shot = 63 mg).

Macchiatos, flat whites and other espresso-based differences

Not every espresso drink uses the same shot count or extraction: a Macchiato (60 ml) in the dataset is 63 mg; a Flat White (160 ml) is listed at 130 mg — because some drinks use a double shot by default. Use the dataset’s espresso values to estimate: each single shot ≈ 63 mg, double ≈ 126 mg.

Drink	Size	Caffeine (mg)
Macchiato	60 ml	63 mg
Flat white	160 ml	130 mg
Cortado	90 ml	79 mg
Affogato	90 ml	63 mg
Mocha	240 ml	95 mg

How Dunkin latte caffeine compares to other chain drinks

Use these dataset comparisons when choosing between chains: Dunkin Medium Latte = 119 mg (414 ml); McDonald’s medium latte = 110 mg (350 ml); Starbucks Grande Caffè Latte = 150 mg (473 ml). For brewed alternatives, Dunkin’s Medium brewed coffee (210 mg) and cold brew (260 mg) deliver substantially more caffeine than a latte of the same brand.

How long the caffeine from a Dunkin latte lasts (decay math)

Caffeine elimination follows an average half-life of about 5.7 hours (population average). That means caffeine halves roughly every 5.7 hours. For the dataset example of a Medium Dunkin Latte (119 mg), expected remaining caffeine is:

Time after drinking	Approx. % remaining	Approx. mg remaining (from 119 mg)
0 hours	100%	119 mg
3 hours	~69%	~82 mg
6 hours	~48%	~57 mg
9 hours	~33%	~39 mg
12 hours	~23%	~27 mg

Halfway at ~5.7 hours leaves about 59.5 mg from a 119 mg dose. Individual factors (age, pregnancy, liver enzymes, interacting drugs) change half-life; the numbers above are population averages, not personal prescriptions.

Health, safety and practical tips

Authoritative guidance: the U.S. FDA recommends up to 400 mg/day for healthy adults; guidance for pregnancy is about 200 mg/day (many sources including the Mayo Clinic and EFSA cite similar limits); the American Academy of Pediatrics discourages caffeine for adolescents. If you’re tracking totals (shots plus drinks), a Medium Dunkin Latte (119 mg) plus a medium Dunkin brewed coffee (210 mg) would exceed 300 mg — nearing the 400 mg daily limit.

To manage intake: ask for fewer shots, choose smaller sizes, or select decaf. Track cumulative caffeine with tools such as CoffeeLog to see exactly how many mg you’ve had across drinks and times.
