Types Of Coffee Beans
Most specialty coffee is Arabica, but bean type is only one layer. Origin, variety, processing, roast, freshness, and brewing often matter more than the species name on the bag.
Arabica
Arabica is the species most associated with specialty coffee. It can taste floral, citrusy, berry-like, tea-like, nutty, chocolatey, or sweet depending on where and how it was grown and processed.
It is harder to grow than Robusta and often prefers cooler highland conditions. That difficulty is one reason good Arabica can cost more.
Robusta
Robusta generally has more caffeine, more body, and more bitterness. It is often used in espresso blends because it can add crema and intensity.
Bad Robusta can taste rubbery, woody, or harsh. Good Robusta can taste cocoa-like, nutty, dense, and sweet. Do not dismiss it completely, but do brew it with care.
Single origin
Single origin means the coffee comes from a specific place: sometimes a country, sometimes a region, farm, estate, cooperative, or even a tiny lot.
The point is traceability. It lets you taste a more specific expression of place and processing. It does not guarantee quality by itself.
Blends
A blend combines coffees to create consistency or a specific flavor profile. A roaster might blend for chocolatey espresso, milk-friendly sweetness, or year-round availability.
Blends are not inferior. A good blend can be more forgiving than a very delicate single origin.
Variety, cultivar, estate, and lot
Variety or cultivar refers to the genetic type of the coffee plant, such as Bourbon, Typica, Caturra, SL28, or Gesha.
Estate usually means the coffee is associated with a specific farm or producer. Lot means a separated batch. Smaller lots are often used when a producer wants to keep a special harvest separate.
