❓ How much caffeine is in different types of coffee drinks?

Caffeine content varies significantly among coffee beverages:

• Regular brewed coffee: 95-200mg per 8 oz cup
• Espresso: 63mg per 1 oz shot
• Cold brew: 150-240mg per 12 oz
• Instant coffee: 60-80mg per 8 oz cup
• Decaf coffee: 2-12mg per 8 oz cup

Factors affecting caffeine content include bean type (Robusta has more caffeine than Arabica), roast level (lighter roasts have slightly more caffeine), brewing method, and serving size. The FDA recommends limiting caffeine intake to 400mg per day for healthy adults, equivalent to about 4-5 cups of regular coffee.
