Q: Which coffee bean has more caffeine?

Robusta generally has about double the caffeine of arabica. That's why it's often used in espresso blends for a stronger kick—handy if you need an extra jolt on an early flight.

Q: Can I brew robusta with the same gear as arabica?

Absolutely. Any standard brewing method—drip, French press, pour-over—works with both. The main differences are taste and grind size preferences, not equipment compatibility.

Q: Which bean is better for a week-long camping trip?

Robusta. It's more resilient to temperature swings and moisture, and its bolder flavor holds up even if your brewing gets a little rough. Arabica can go stale faster and its subtle notes get lost outdoors.
