The caffeine content in coffee can vary significantly based on several factors:
- Regular brewed coffee: 95-200mg per 8 oz cup
- Espresso: 63mg per 1 oz shot
- Cold brew: 100-200mg per 8 oz
- Instant coffee: 60-80mg per 8 oz
- Decaf: 2-12mg 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 limiting caffeine intake to 400mg per day for healthy adults.
