Snobbism among coffee drinkers can rival that of wine drinkers, but the fact is that an astonishing world of coffee tastes awaits anyone willing to venture beyond mass-marketed commercial brands. Specialty coffees that clearly state the country, region or estate of origin can provide a lifetime of tasting experiences. By all means look for 100% pure Arabica beans. The cheap alternatives may contain Robusta beans, noted for their higher caffeine content but harsh flavors. “Nasty” is a term commonly linked to Robusta coffees by Arabica devotees.
