How much caffeine is in Brewed Coffee?

A standard 8 oz cup of drip coffee carries about 95 mg of caffeine, the everyday baseline most other drinks get measured against. It's the reference point for a typical morning lift, though the real number drifts with roast, grind and how long the water sits with the grounds.

Typical drip coffee; ranges ~70–140 mg/8oz by roast, grind and brew time.

Will Brewed Coffee affect your sleep?

From 95 mg, a single cup needs roughly five hours to fall under 50 mg, so an afternoon coffee can still be half-present at dinner. A cup with lunch is usually clear by bedtime; one after 5 p.m. is the kind that lingers.
