Peet's Coffee Caffeine Levels: Complete Breakdown

A standard 240 ml Peet's cold brew contains 200 mg of caffeine.

• Cold brew (240 ml): 200 mg — one of Peet's highest single-serving doses.
• Pour over (240 ml): 145 mg — stronger than drip and instant per 240 ml.
• Drip coffee (240 ml): 96 mg; decaf (240 ml): 3 mg.
• Single espresso (30 ml): 63 mg; double: 126 mg.

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.

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%.

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.

Authorities referenced: USDA FoodData Central for reference-method data, FDA and EFSA for safety limits, Mayo Clinic and the American Academy of Pediatrics for clinical guidance on pregnancy and adolescent use.

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.

If I drink a 240 ml Peet's cold brew at 4 PM and another at 8 PM, how much caffeine is in my system at 10 PM?

At 10 PM you would have about 323 mg of caffeine immediately after the 8 PM pour, and about 156 mg remaining by 4 AM (six hours later). These numbers come from summing the remaining caffeine from each dose using a population-average half-life of 5.7 hours (342 minutes) per the decay model on this page.

Cumulative residual caffeine is the sum of remaining caffeine from each prior dose.

Step-by-step arithmetic: the first 240 ml cold brew is 200 mg; after 4 h (4 PM → 8 PM) remaining = 200 × 0.5^(4/5.7) ≈ 200 × 0.615 = 123 mg. Add the second cold brew (200 mg) at 8 PM to get 123 + 200 = 323 mg at 8 PM. To get the amount at 10 PM (2 h after the second dose) we compute 323 × 0.5^(2/5.7) ≈ 323 × 0.781 = ~252 mg at 10 PM; at 4 AM (6 h after 10 PM) remaining ≈ 323 × 0.5^(6/5.7) ≈ 323 × 0.483 = ~156 mg. Use our caffeine half-life calculator to plug your times and doses and see the same arithmetic automatically.

Which Peet's drink will push me past the FDA 400 mg/day guideline the fastest?

Two 240 ml cold brews (200 mg each) will give 400 mg total and hit the FDA guideline exactly; one 240 ml nitro cold brew (215 mg) plus a 240 ml pour-over (145 mg) gives 360 mg and a later 240 ml latte (68 mg) would push you to 428 mg, over the FDA number. The FDA sets ~400 mg/day as a general safe upper limit for healthy adults (U.S. Food and Drug Administration).

Daily limit is the recommended maximum daily intake from a guideline authority.

Concrete examples using dataset values: 200 mg (cold brew) + 200 mg (cold brew) = 400 mg; 215 mg (nitro) + 145 mg (pour over) + 68 mg (240 ml latte) = 428 mg. If you want per-weight guidance or a different target, see our safe daily limit by body weight and the daily caffeine intake guide for personalized calculators.

Can I use a Peet's drink as a pre-workout dose and how much should I pick?

Yes—many people use a single Peet's drink as a pre-workout stimulant; a common practical dose is 100–200 mg taken 30–60 minutes before exercise, which you can get from a 240 ml cold brew (200 mg) or a 240 ml pour-over (145 mg). Evidence and dosing strategies are summarized in our pre-workout dosage guide (pre-workout caffeine dosage guide).

Pre-workout dose is the amount of caffeine consumed shortly before exercise to enhance performance.

Examples from Peet's dataset: a 240 ml cold brew provides 200 mg (a full high-end single dose), a 240 ml pour-over provides 145 mg, and a 240 ml latte provides 68 mg. If you routinely train late in the day, remember that 200 mg at 7 PM would leave roughly 96 mg at 1 AM using the 5.7 h half-life model (200 × 0.5^(6/5.7) ≈ 96), which can affect sleep; use our latest cup before bed tool to schedule a pre-workout without cutting into sleep time.

How should pregnancy or smoking change what I order at Peet's?

Pregnancy and smoking move caffeine metabolism in opposite directions: pregnancy slows elimination and authorities advise keeping intake near or below 200 mg/day, while smoking speeds elimination so doses clear faster. The EFSA gives a 200 mg/day recommendation for pregnancy and discusses single-dose considerations (EFSA 2015 opinion).

CYP1A2 is the liver enzyme primarily responsible for caffeine metabolism.

Practical ordering rules: during pregnancy follow the EFSA/health-system guidance and keep total daily Peet's caffeine at or below 200 mg — for example one 240 ml pour-over (145 mg) plus a 240 ml latte (68 mg) would exceed that to 213 mg, so choose a 240 ml decaf (3 mg) or a single espresso (63 mg) instead. For smokers the faster metabolism means caffeine effects wear off sooner, but smoking carries its own health risks; if you want low evening stimulation choose a 240 ml latte (68 mg) or decaf (3 mg). See our pregnancy safety guides for more detail: caffeine pregnancy guide and caffeine during pregnancy: how much is safe.

How concentrated is caffeine across Peet's drinks (mg per 100 ml)?

Caffeine concentration is useful when you compare strength independent of cup size; calculate it as mg divided by ml times 100. Below are concentrations for common Peet's drinks using the dataset values.

Concentration is milligrams of caffeine per 100 milliliters of drink.

Calculations from the dataset: pour-over 145 mg / 240 ml = 60.4 mg per 100 ml; drip coffee 96 mg / 240 ml = 40.0 mg per 100 ml; cold brew 200 mg / 240 ml = 83.3 mg per 100 ml; nitro cold brew 215 mg / 240 ml = 89.6 mg per 100 ml; flat white 130 mg / 160 ml = 81.3 mg per 100 ml; latte 68 mg / 240 ml = 28.3 mg per 100 ml. Use our side-by-side drink comparison if you want to compare concentration plus serving size at a glance, or consult the cold brew caffeine guide for dilution and concentrate notes.

How late can I drink a Peet's cold brew and still avoid losing more than an hour of sleep?

To avoid reducing sleep by more than about one hour, avoid taking ~400 mg of caffeine within 6 hours of bedtime; a single 200 mg 240 ml cold brew taken 6 hours before bed still leaves ~96 mg at bedtime using the 5.7 h half-life model and may shorten sleep—studies show 400 mg six hours before bed cut objective sleep time by more than an hour (Drake et al., 2013).

Sleep impact is the measurable reduction in sleep caused by stimulant exposure near bedtime.

Example arithmetic: one 240 ml cold brew (200 mg) consumed 6 hours before sleep leaves 200 × 0.5^(6/5.7) ≈ 96 mg at lights-out. If you had two cold brews earlier in the day the residual could be much higher—use the latest cup before bed tool to calculate timing for your specific bedtime and doses.

Bottom line

Peet's menu ranges from almost-caffeine-free decaf (3 mg per 240 ml) up to concentrated nitro cold brew (215 mg per 240 ml) with standard 240 ml cold brew at 200 mg and a double espresso at 126 mg — these are the dataset values used throughout this page. For elimination we use a first-order decay model with a population-average half-life of 5.7 hours (342 minutes); remaining mg after t hours = original mg × 0.5^(t/5.7). Using that model, a 240 ml cold brew (200 mg) leaves about 138 mg after 3 h, ~96 mg after 6 h, ~66 mg after 9 h and ~46 mg after 12 h.

The general safety benchmarks: the U.S. FDA sets ~400 mg/day for healthy adults (FDA), and the EFSA 2015 opinion recommends a 200 mg/day ceiling during pregnancy (EFSA). Practical takeaways: one 240 ml cold brew is 200 mg (half the FDA limit); two cold brews equal 400 mg and meet the FDA upper limit exactly. If you need to time doses around sleep or workouts, use our caffeine half-life calculator, last cup before bed tool, or the pre-workout dosage guide to pick drinks and times that fit your goals.
