Species comes first
Arabica and Robusta are species-level commercial categories. A cultivar or cultivated variety describes plant material more specifically. World Coffee Research maintains catalogues covering varieties and their agronomic characteristics.
Neither species alone nor a variety name guarantees cup quality. Growing environment, management and post-harvest preparation also matter.
Origin describes place
Names such as Gayo, Chikmagalur or Guji give a coffee geographical context. A region can contain many farms, cultivars and processes. A regional offer is therefore not one uniform product.
Request traceability records before making origin claims. Where geographical indications apply, verify eligibility rather than relying on marketing wording.
Process describes treatment
Washed, natural, wet-hulled and monsooned describe different post-harvest approaches. They are not interchangeable with cultivar or certification terminology. A natural coffee is not necessarily organic.
Processing descriptions should be backed by supplier records and a representative sample. Experimental terminology requires particularly clear definitions.
Grade and score add other dimensions
Bean size and defect grades describe a preparation standard, while a sensory score describes an evaluation under a stated protocol. Neither should be invented from an origin name.
A useful purchase specification separates species, cultivar if documented, producing area, processing, harvest, grade and sample approval. Keeping the categories separate reduces misunderstandings and helps make repeat orders comparable.
