Snapshot: Peet's caffeine by common drink
This table lists measured caffeine values Peet's publishes or that align with FoodData-style sampling. Serving volumes are shown as they commonly appear on café menus.
| Drink (typical) | Serving | Caffeine (mg) |
|---|---|---|
| Cold brew | 240 ml | 200 mg |
| Nitro cold brew | 240 ml | 215 mg |
| Pour over | 240 ml | 145 mg |
| Drip coffee | 240 ml | 96 mg |
| French press | 240 ml | 107 mg |
| Instant coffee | 240 ml | 62 mg |
| Decaf coffee | 240 ml | 3 mg |
| Single espresso | 30 ml | 63 mg |
| Double espresso | 60 ml | 126 mg |
| Flat white | 160 ml | 130 mg |
| Mocha | 240 ml | 95 mg |
| Latte | 240 ml | 68 mg |
Espresso and espresso-based drinks
Peet's single espresso (30 ml) contains 63 mg and the double is 126 mg. Many milk-based drinks show lower total caffeine than straight espresso per serving because milk increases volume without adding caffeine — e.g., a 240 ml latte is 68 mg while a 60 ml double espresso is 126 mg. Exceptions exist: a flat white (160 ml) is listed at 130 mg because it typically uses a stronger extraction or a double shot.
Brewing methods: why pour over, drip, French press and instant differ
Caffeine extraction depends on grind size, water temperature, contact time and coffee-to-water ratio. Peet's pour over at 240 ml (145 mg) shows higher caffeine than drip (96 mg) because pour-over pours tend to use finer grind or higher coffee dose. French press (240 ml, 107 mg) captures more oils and soluble solids, raising caffeine versus drip. Instant coffee is concentrated differently and is lower (62 mg per 240 ml).
Cold brew and nitro: concentrated, longer steep, bigger doses
Cold brew is steeped long at room or refrigerated temps, producing a concentrate that is often served diluted; Peet's 240 ml cold brew contains 200 mg and nitro cold brew 215 mg. These are the highest routine single servings on Peet's menu and can push a consumer toward daily limits quickly — two 240 ml cold brews exceed the FDA's 400 mg/day guideline.
How long Peet's caffeine stays in your body (decay math)
Use a population-average half-life of 5.7 hours: caffeine in plasma halves roughly every 5.7 hours. Practical approximations: after 3 h ≈69% remains, 6 h ≈48%, 9 h ≈33%, 12 h ≈23%.
| Original dose | After 3 h (~69%) | After 6 h (~48%) | After 9 h (~33%) | After 12 h (~23%) |
|---|---|---|---|---|
| Pour over — 145 mg | ~100 mg | ~70 mg | ~48 mg | ~33 mg |
| Double espresso — 126 mg | ~87 mg | ~60 mg | ~42 mg | ~29 mg |
| Cold brew — 200 mg | ~138 mg | ~96 mg | ~66 mg | ~46 mg |
Example: drinking a 240 ml Peet's cold brew (200 mg) at 4 PM would leave roughly 96 mg in your system at 10 PM (6 h later) and about 46 mg by 4 AM. These are population-average estimates; genetics, liver function, pregnancy, smoking and medications change half-life significantly (CYP1A2 activity).
What changes the caffeine number for the same drink?
Variables that move the mg up or down: bean origin (Arabica vs Robusta), roast level (darker roasts often yield slightly less caffeine by volume), grind and tamp for espresso, coffee-to-water ratio, extraction time and serving size. Peet's menu values are standardized; actual café pours can differ by barista and location.
Health, safety and timing
Guidelines: the FDA cites ~400 mg/day as a general safe upper limit for healthy adults; EFSA reviews similar ranges. For pregnancy, most authorities recommend keeping caffeine near or below 200 mg/day (consult your clinician). The American Academy of Pediatrics discourages caffeine for adolescents; parents should limit intake. Caffeine can worsen anxiety, trigger palpitations, and disrupt sleep; stop caffeine 6–8 hours before bedtime if you are sensitive.

Compare Peet's to other chains
Peet's cold brew (200 mg/240 ml) is close to Starbucks Cold Brew (205 mg per 473 ml grand) when adjusted for volume, and stronger than many drip offerings. For reference, Starbucks blonde single shot is 85 mg; Dunkin' medium brewed is 210 mg for a much larger cup. When comparing, always check serving sizes and concentration (mg per 100 ml) — Peet's pour-over (60.4 mg/100 ml) is one of the stronger brewed formats.
Track and reduce caffeine intentionally
If you want to track exact intake — including mixing drinks and calculating leftover caffeine over the day — use a tracker such as CoffeeLog to log drinks and see cumulative mg and decay. Simple reduction strategies: choose a smaller size, switch to single-shot milk drinks, order decaf (3 mg per 240 ml), or dilute cold brew. For quick swaps: a 240 ml latte is 68 mg versus a 240 ml cold brew at 200 mg.

Bottom line
Peet's range runs from almost-caffeine-free decaf (3 mg per 240 ml) to concentrated nitro cold brew (215 mg per 240 ml). Know the serving size and brew method — and use a log like CoffeeLog or a spreadsheet to keep daily totals under safety guidance.
Frequently asked questions
How much caffeine is in Peet's cold brew (240 ml)?
Peet's cold brew (240 ml) contains 200 mg of caffeine. Nitro cold brew is slightly higher at 215 mg per 240 ml.
Is Peet's decaf coffee caffeine-free?

How does Peet's espresso compare to Starbucks shots?
Peet's single espresso is 63 mg per 30 ml; Starbucks Blonde espresso shot is 85 mg per 30 ml. Shot-to-shot differences reflect bean roast and extraction.
How long after a Peet's pour-over will the caffeine wear off?
Using a 5.7 h half-life: a 145 mg pour-over leaves ~70 mg after 6 h and ~33 mg after 12 h. Individual metabolism varies.
Is it safe to drink Peet's coffee while pregnant?
Most authorities advise limiting caffeine to ~200 mg/day during pregnancy. Check with your clinician — this is informational, not medical advice.
How can I lower my caffeine intake at Peet's?
Choose decaf (3 mg), smaller sizes, single shots, or milk-based drinks (a 240 ml latte is 68 mg). Track totals with an app like CoffeeLog to avoid accidental excess.
