Do you know how much caffeine in coffee?

Regular Coffee: A standard 8-ounce cup of brewed coffee typically contains about 95 milligrams of caffeine.

Espresso Shot: A 1-ounce shot of espresso contains around 63 milligrams of caffeine.

Instant Coffee: An 8-ounce cup of instant coffee usually has between 30 to 90 milligrams of caffeine.

Decaf Coffee: While decaffeinated coffee isn't entirely caffeine-free, it typically has only 2 to 5 milligrams of caffeine per 8-ounce cup.

Cold Brew Coffee: Cold brew coffee can pack a punch, with caffeine levels ranging from 100 to 200 milligrams or more in an 8-ounce serving.

Roast Type: Dark roast coffee isn't necessarily stronger; caffeine content remains similar to light and medium roasts.

Bean Type: The type of coffee bean (e.g., Arabica or Robusta) can affect caffeine levels, with Robusta having more caffeine.

Serving Size Matters: Remember, these numbers are for typical 8-ounce cups, so adjust for larger or smaller servings accordingly.
