Frequently Asked Questions
Is Arabica better than Robusta?▼
Not necessarily. Arabica has more complex flavors preferred in specialty coffee, but Robusta produces better crema in espresso and has nearly double the caffeine. Many Italian espresso blends deliberately include Robusta.
Which has more caffeine?▼
Robusta has almost twice the caffeine of Arabica (2.2-2.7% vs 1.2-1.5%). This higher caffeine also makes Robusta plants more resistant to pests.
Why is Arabica more expensive?▼
Arabica requires specific growing conditions (high altitude, moderate temperatures, shade), is more susceptible to disease, and yields less fruit per plant. These factors increase production costs.
