how much caffeine in one shot of espresso starbucks

A single shot of Starbucks espresso has about 75 mg of caffeine.

Quick Scoop

• A standard Starbucks solo espresso (about 1 oz / 30 ml) ≈ 75 mg caffeine.

• A double shot (doppio) is roughly 150 mg caffeine.

• This is a bit higher than the general average for espresso, which is usually quoted around 63–64 mg per 1 oz shot.

Why the number can vary

• Grind size, bean type, and roast level all change how much caffeine ends up in the cup.

• Different cafes and machines can produce shots ranging from about 25 mg up to over 200 mg, though that extreme range is not typical for Starbucks because their process is standardized.

How this fits into your day

Many health guidelines suggest most healthy adults can have up to about 400 mg of caffeine per day, so one Starbucks shot is under a quarter of that rough limit. For example, a latte with two shots (about 150 mg) will usually have less caffeine than a 12 oz strong drip coffee or cold brew of the same size.
