About this drink
A single espresso shot is the building block of most coffee shop drinks. Despite the small volume, the caffeine concentration is intense — but the total dose is less than a brewed cup. Two shots ≈ one Grande Latte ≈ one short drip coffee.
Ingredients: Finely ground espresso beans, 9 bars pressurized hot water
When will it clear your system?
65 mg metabolizes quickly thanks to the small volume. An espresso shot at 4pm typically clears by bedtime for most adults.
Based on caffeine's 5-hour half-life, a Espresso Shot consumed at 2:00 PM drops below the sleep-safe threshold (~20 mg) by approximately 22:30 the same evening.
Where this fits in a daily limit
That's about 33% of the 200 mg pregnancy guideline and 16% of the 400 mg general adult daily limit — comfortably moderate.
