Cafe Bustelo Caffeine: Complete Espresso Guide

A single 30 ml shot of Cafe Bustelo espresso contains 63 mg of caffeine (a double is 126 mg).

• Single espresso (30 ml): 63 mg.
• Double espresso (60 ml) / large latte (350 ml, 2 shots): 126 mg.
• Instant Cafe Bustelo-style coffee (240 ml): 62 mg; cold brew (240 ml): 200 mg.
• Decaf (240 ml) contains 3 mg — essentially negligible but not zero.

Cafe Bustelo caffeine by product type

Cafe Bustelo is sold and brewed in multiple ways: espresso shots from ground espresso roast, brewed drip/pourover, instant, and cold-brewed preparations. Use the table below for the mg values most relevant when you're measuring cups or shots.

Drink (common Cafe Bustelo style)	Volume	Caffeine (mg)
Espresso (single)	30 ml	63 mg
Espresso (double)	60 ml	126 mg
Ristretto	20 ml	63 mg
Americano	240 ml	126 mg
Latte (single shot)	240 ml	68 mg
Latte (large, 2 shots)	350 ml	126 mg
Cappuccino	180 ml	63 mg
Instant coffee (prepared)	240 ml	62 mg
Cold brew	240 ml	200 mg
Decaf (prepared)	240 ml	3 mg

Instant vs. ground espresso: practical differences

Instant coffee (240 ml) is listed at 62 mg per cup in the dataset; that’s similar to a single espresso in total mg but much lower concentration per ml. By contrast, espresso shots concentrate the same or more caffeine into 20–60 ml (a 20 ml ristretto still contains 63 mg), so strength perception is higher. Decaf remains ~3 mg per 240 ml.

How Cafe Bustelo compares to other brands and styles

Single shots from Cafe Bustelo-style espresso (63 mg/30 ml) are lower than a Starbucks Blonde espresso shot (85 mg/30 ml) in the dataset. For brewed coffees, pour over clocks 145 mg per 240 ml while drip is 96 mg — both can be what you get if you brew Cafe Bustelo as a pour over or drip. Cold brew is much higher at 200 mg per 240 ml.

Brewing methods and what changes the caffeine amount

Primary factors that change caffeine in your cup: coffee dose (grams of coffee), grind size, extraction time, water temperature and brew method. Specific notes:

• Espresso vs ristretto: a ristretto uses less water but the dataset shows the same 63 mg for ristretto (20 ml) and single espresso (30 ml), so ristretto has higher mg/ml concentration.
• Brew strength: pour over (240 ml) is 145 mg in the dataset — far stronger than drip at 96 mg, because grind, ratio and extraction differ.
• Cold extraction: cold brew (240 ml) is 200 mg and nitro cold brew is 215 mg per 240 ml — considerably higher caffeine per cup.

Caffeine decay and timing: how much remains over hours

The population-average half-life for caffeine is about 5.7 hours. That means caffeine roughly halves every ~5.7 hours (after 3 h ≈ 69% remains, after 6 h ≈ 48%, after 9 h ≈ 33%, after 12 h ≈ 23%). The table below shows remaining mg for common Cafe Bustelo-style doses.

Dose	0 h	3 h (~69%)	6 h (~48%)	9 h (~33%)	12 h (~23%)
Single espresso — 63 mg	63 mg	43 mg	30 mg	21 mg	14 mg
Double espresso — 126 mg	126 mg	87 mg	60 mg	42 mg	29 mg
Cold brew — 200 mg	200 mg	138 mg	96 mg	66 mg	46 mg
Nitro cold brew — 215 mg	215 mg	148 mg	103 mg	71 mg	49 mg

Health, safety and recommended limits

U.S. FDA guidance lists 400 mg/day as a common upper limit for healthy adults; for pregnancy many authorities (including EFSA and clinical guidance summarized by Mayo Clinic) recommend ~200 mg/day. The American Academy of Pediatrics discourages caffeine for adolescents. If you have heart disease, anxiety disorders, are pregnant, or take medication, consult your clinician before changing intake.

Practical tracking and tips

Measure caffeine by recording the preparation: count espresso shots (63 mg per single shot), note cup sizes (cold brew 200 mg per 240 ml), and log decaf as 3 mg per 240 ml. Apps like CoffeeLog let you log shots and cups and compute total mg, decay over time and daily totals so you don’t surprise your sleep or exceed 400 mg/day.
