Chameleon Cold Brew: Complete Caffeine Content Guide

A 240 ml serving of Chameleon-style cold brew contains 200 mg of caffeine (per the cold brew value in the dataset).

• 240 ml cold brew (Chameleon-style): 200 mg.
• Nitro cold brew (240 ml) is slightly higher at 215 mg; a single espresso shot (30 ml) is 63 mg.
• After drinking 200 mg, expect about 96 mg to remain after 6 hours and about 46 mg after 12 hours (population-average half-life ≈ 5.7 h).
• FDA recommends a 400 mg/day upper limit for healthy adults; pregnancy guidance is lower (~200 mg/day); the American Academy of Pediatrics discourages caffeine for adolescents.

Caffeine content in a standard Chameleon-style cold brew

The dataset value for a 240 ml cold brew is 200 mg of caffeine; this is the clearest direct comparison point for Chameleon Cold Brew as a ready-to-drink or diluted serving. Many cold brews marketed as "concentrate" or "ready-to-drink" will fall near this number when served at standard dilution and serving size.

How cold brew compares to common coffees and drinks

Cold brew frequently has higher caffeine per 240 ml than drip or French press because it often uses more coffee per water and a long extraction time. For reference, drip coffee (240 ml) is 96 mg and pour-over (240 ml) in the dataset is 145 mg.

Drink / serving	Volume	Caffeine (mg)
Chameleon-style cold brew (representative)	240 ml	200 mg
Nitro cold brew	240 ml	215 mg
Drip coffee	240 ml	96 mg
Pour over	240 ml	145 mg
Single espresso (shot)	30 ml	63 mg

Understanding cold brew concentrate and why numbers vary

Chameleon sells both ready-to-drink and concentrate products; the dataset gives a standard cold brew value but not a brand-specific concentrate mg. Concentrates are brewed stronger and intended to be diluted. Without the product label you must treat concentrate numbers as estimates: a diluted serving can match the 200 mg/240 ml value, while an under-diluted cup can exceed it.

Check the bottle for either a stated mg or a recommended dilution ratio. If the label is silent, measure brewed concentrate, dilute per package directions, and compare with the 200 mg benchmark above. Use CoffeeLog to log label values or compute mg automatically when you track servings.

Espresso-based Chameleon offerings and caffeine density

If you order an espresso-style beverage made with single or double shots, use the dataset espresso values: a single 30 ml shot is 63 mg and a double 60 ml is 126 mg. Many coffeehouse lattes and cappuccinos will have similar totals when made with standard shots.

Specialty flavors (Irish Cream, seasonal blends) and their effect on caffeine

Flavorings (cream, syrups) alter taste and calories but usually add negligible caffeine. The caffeine content is driven by the coffee portion. Unless a flavoring includes coffee extract or extra espresso shots, assume the same mg as an undressed cold brew or the underlying drink listed in the dataset.

Caffeine decay: how much remains over time (population-average)

Caffeine elimination follows exponential decay; population-average half-life ≈ 5.7 hours. Use the table below to see remaining mg from two common servings: 240 ml cold brew (200 mg) and a single espresso (63 mg). These values are model estimates for a typical adult — individual metabolism varies with genetics, medications, pregnancy, age and liver function.

Elapsed time	Remaining from 200 mg cold brew	Remaining from 63 mg espresso
0 hours	200 mg	63 mg
3 hours (~69% remain)	≈ 138 mg	≈ 43 mg
6 hours (~48% remain)	≈ 96 mg	≈ 30 mg
9 hours (~33% remain)	≈ 66 mg	≈ 21 mg
12 hours (~23% remain)	≈ 46 mg	≈ 14 mg

Health, safety and timing

Federal guidance and medical authorities provide useful limits: the U.S. Food and Drug Administration cites 400 mg/day as a maximum for healthy adults; many clinicians advise a safer habitual target below that. For pregnancy, agencies such as the European Food Safety Authority and the American Pregnancy Association often recommend limiting intake to ~200 mg/day. The American Academy of Pediatrics discourages caffeine for adolescents. If you have liver disease, are on interacting medication, pregnant, or have heart rhythm or anxiety disorders, consult your clinician before consuming high-caffeine drinks.

Practical tips and tracking

To manage intake: (1) measure serving size — many cold-brew servings are 240–473 ml; (2) read the label for concentrate dilution; (3) track totals across drinks — a 240 ml cold brew is 200 mg and a second cup or an added shot can quickly approach or exceed 400 mg. CoffeeLog makes logging servings and summing mg easy so you can see daily totals and timing relative to sleep.

Sources and how these numbers were chosen

Numbers in this guide use the dataset values for standard beverage servings (cold brew 240 ml = 200 mg; nitro cold brew 240 ml = 215 mg; espresso shot 30 ml = 63 mg) and established pharmacokinetic half-life guidance (population-average 5.7 hours). For general safety limits I referenced FDA, EFSA, Mayo Clinic and American Academy of Pediatrics recommendations.
