Packaged Iced Coffee: Caffeine Content Comparison

International Delight ready-to-drink iced coffee isn’t listed in the dataset; a reasonable estimate is 80–150 mg of caffeine per 355–473 ml bottle depending on flavor and formulation.

• 80–150 mg — estimated caffeine range for a typical 355–473 ml bottled iced coffee (International Delight not listed in the dataset).
• 200 mg — a 240 ml cold brew in the dataset contains 200 mg of caffeine (one of the highest per-serving values listed).
• 400 mg/day — FDA guideline upper limit for most healthy adults; pregnant people should limit to ~200 mg/day (Mayo Clinic, FDA).
• ~96 mg — a 240 ml dripped cup in the dataset contains 96 mg, roughly half the caffeine of a 240 ml cold brew (200 mg).

Packaged iced coffee caffeine overview

“Packaged iced coffee” covers refrigerated dairy-blended bottles, shelf-stable RTD (ready-to-drink) cans, and bottled cold-brew concentrates. The dataset shows large differences by method: concentrated cold brew and nitro cold brew are the most caffeine-dense by volume, while milk-forward lattes and bottled iced teas are much lower. Always check the label; brands vary formulation and serving size.

How International Delight compares (what we know and what we estimate)

International Delight bottled iced coffee is not included in the provided dataset, so we must rely on product labels and manufacturer disclosures: many flavored RTD coffees fall in roughly 80–150 mg per 355–473 ml. Lower values appear when the product is milk-forward or uses decaf/instant; higher values appear when the label advertises "extra caffeine" or uses cold-brew concentrate. If you need accuracy, scan the nutrition facts and log it in an app like CoffeeLog to track exact mg.

Caffeine across popular drinks (dataset comparison)

Drink / serving	Serving size	Caffeine (mg)
Cold brew	240 ml	200 mg
Nitro cold brew	240 ml	215 mg
Starbucks Cold Brew (Grande)	473 ml	205 mg
Drip coffee	240 ml	96 mg
Starbucks Blonde Espresso (shot)	30 ml	85 mg
Espresso (double)	60 ml	126 mg
Iced tea (bottled)	355 ml	45 mg
Monster (energy)	473 ml	160 mg
5-Hour Energy	57 ml	200 mg
Coca-Cola	355 ml	34 mg

Note the per-serving volume differences: a 473 ml Starbucks Cold Brew at 205 mg is similar in total caffeine to a concentrated 240 ml cold brew at 200 mg; per 100 ml, cold brew is much stronger.

What determines caffeine in packaged iced coffee

Key variables: bean origin and roast, brew method, coffee-to-water ratio, extraction time, dilution with milk or water, and whether the product uses arabica, robusta, or a blend. Dataset examples show method effects: pour-over (240 ml) contains 145 mg while drip (240 ml) is 96 mg; cold brew (240 ml) is 200 mg. USDA FoodData Central compiles similar variability for brewed coffee types.

How long caffeine from a bottle lasts (half-life math and concrete examples)

Population-average caffeine half-life ≈ 5.7 hours. That means roughly 69% remains after 3 hours, 48% after 6 hours, 33% after 9 hours, and 23% after 12 hours. Below is the decay applied to two dataset doses so you can plan sleep timing.

Time after drinking	% remaining (approx)	Remaining from 200 mg cold brew (240 ml)	Remaining from 205 mg Starbucks Cold Brew (473 ml)
0 h	100%	200 mg	205 mg
3 h	~69%	138 mg	141 mg
6 h	~48%	96 mg	98 mg
9 h	~33%	66 mg	68 mg
12 h	~23%	46 mg	47 mg

Practical: a 240 ml cold brew taken at 4 pm still leaves ~96 mg at 10 pm — often enough to disrupt sleep. Mayo Clinic and sleep research commonly recommend avoiding caffeine 6–8 hours before bedtime for sensitive people.

Health, safety, and special populations

Guidelines: FDA recommends ≤400 mg/day for most healthy adults; Mayo Clinic and FDA advise pregnant people to limit to about 200 mg/day. The American Academy of Pediatrics discourages caffeine-containing energy drinks and recommends limiting caffeine in adolescents. Excessive intake risks palpitations, anxiety, and sleep disruption; seek medical advice for symptoms or concerns.

Shopping and tracking tips

Read serving size and caffeine disclosure on the bottle. If the label lacks mg, compare to similar items in USDA FoodData Central or use an app like CoffeeLog to record and sum milligrams across drinks and foods. To lower intake: choose milkier formulas, diluted concentrates, half-caff blends, or decaf (dataset: decaf 240 ml = 3 mg).

Bottom line

Packaged iced coffees span a wide range; use the label when available. If you assume a typical RTD bottled iced coffee falls between 80–150 mg per 355–473 ml, you’ll be conservative; cold-brew RTDs can match 200+ mg per serving, so treat them like a strong cup of coffee when planning sleep or daily totals.
