The caffeine content in coffee varies significantly depending on several factors:

  • Regular drip coffee: 95-200mg per 8 oz cup
  • Espresso: 63mg per 1 oz shot
  • Cold brew: 100-200mg per 8 oz
  • Instant coffee: 30-90mg per 8 oz

Factors affecting caffeine content include:

  • Bean type (Robusta has more caffeine than Arabica)
  • Roast level (contrary to popular belief, light roasts have slightly more caffeine)
  • Brewing method and time
  • Serving size

For reference, the FDA suggests a safe daily caffeine limit of 400mg for healthy adults, equivalent to about 4-5 cups of regular coffee.
