Teneur en caféine selon la taille du Dunkin Cold Brew (valeurs exactes et estimées)

Only one official Dunkin Cold Brew value is published in the dataset: the Medium size (710 ml) is listed at 260 mg. Smaller and larger Dunkin sizes are commonly offered in stores but exact official mg values are not in the dataset; below are transparent estimates and the single confirmed number you can rely on.

Confirmé

Dunkin Cold Brew (Medium, 710 ml): 260 mg — this is the dataset value you should use when counting caffeine.

Estimates for other sizes

• Small (estimate): roughly 1/2–2/3 of Medium → estimate ~130–175 mg (not in dataset).
• Large (estimate): roughly 1.25–1.5× Medium → estimate ~325–390 mg (not in dataset).

When exact labeling matters (pregnancy, medication, sleep), use the Medium 260 mg figure or ask staff for an official nutrition sheet at the location.

How Dunkin Cold Brew compares to other popular drinks

Cold brew is among the higher-caffeine brewed coffees because it uses a higher coffee-to-water ratio and long extraction time. The table below compares Dunkin Cold Brew (Medium) to several dataset values from Dunkin, other coffees, and popular chains.

Drink	Serving	Caffeine (mg)
Dunkin Cold Brew	710 ml (Medium)	260 mg
Dunkin' Original Blend (hot)	414 ml (Medium)	210 mg
Dunkin Latte	414 ml (Medium)	119 mg
Cold brew (generic)	240 ml	200 mg
Nitro cold brew (generic)	240 ml	215 mg
Drip coffee	240 ml	96 mg
Starbucks Cold Brew (Grande)	473 ml	205 mg

Caffeine decay: how much remains in your body after drinking Dunkin Cold Brew

Population-average half-life for caffeine is ~5.7 hours. That means caffeine concentration roughly halves every 5.7 hours; practical remaining percentages are: after 3 h ≈ 69%, after 6 h ≈ 48%, after 9 h ≈ 33%, after 12 h ≈ 23%.

Starting from the confirmed Dunkin Medium dose of 260 mg, here are concrete remaining amounts (rounded):

Time after dose	% remaining	Mg remaining (from 260 mg)
0 hours	100%	260 mg
3 hours	≈69%	≈179 mg
6 hours	≈48%	≈125 mg
9 hours	≈33%	≈86 mg
12 hours	≈23%	≈60 mg

Example interpretation: if you drink a 260 mg Dunkin Cold Brew at 4 PM, a population-average person would still have ~125 mg of caffeine at 10 PM — likely enough to affect sleep for some people.

Factors that make the caffeine number vary

Cold brew caffeine can shift because of:

• Concentration: many shops serve a cold-brew concentrate diluted to taste; concentrate has more mg per ml.
• Bean and roast: lighter roasts can yield slightly more extractable caffeine; grind and origin matter.
• Steep time and coffee-to-water ratio: longer steep and higher ratio → more caffeine.
• Serving variability: real-world pours and added shots change mg; always use the labeled figure when available.

Health, safety and timing

Recommendations from authorities: the FDA cites 400 mg/day as a reasonable upper limit for most healthy adults; during pregnancy many experts and EFSA advise limiting to roughly 200 mg/day, and the American Academy of Pediatrics discourages caffeine for adolescents. For acute concerns (palpitations, severe anxiety), contact a healthcare professional immediately.

Practical guidance: a single Dunkin Medium (260 mg) is over half the 400 mg-adult limit and meets or exceeds pregnancy day limits, so pregnant people and those sensitive to caffeine should avoid or choose smaller servings. For sleep, consider avoiding cold brew within 6–10 hours of planned bedtime because substantial caffeine remains during that window.

Track your intake and next steps

If you drink cold brew regularly, track exact servings and times — apps like CoffeeLog can log the 260 mg Medium value automatically and sum daily totals so you stay under your personal limit. For medication interactions, pregnancy, heart conditions or seizure disorders, discuss caffeine use with a clinician and use the FDA, Mayo Clinic, and EFSA guidelines as reference points.
