A varietal — properly a cultivar — is the specific variety of Coffea arabica the plant belongs to, in the same way a wine grape is Pinot Noir or Cabernet.
Why it matters
Varietal sets the potential of the cup. Some varieties are capable of extraordinary aromatics; others are capable of reliable, decent, high yields.
Geisha is famous because it tastes of jasmine and bergamot in a way most varieties cannot, regardless of how well they are grown.
The two ancestors
Almost everything traces to Typica and Bourbon, both descended from a tiny founding population taken out of Yemen. That genetic narrowness is why coffee is so vulnerable to disease.
The families
Heirloom — Ethiopia’s thousands of undocumented local varieties. Traditional — Typica, Bourbon, Caturra, Catuai, SL28. Hybrids — Catimor, Sarchimor, Castillo: bred for leaf rust resistance, usually at some cost to the cup. Exceptional — Geisha, SL28, Pacamara, Sudan Rume.
The trade-off
Disease resistance and yield generally cost cup quality. A farmer choosing Castillo over Caturra is choosing survival over score, and that is a rational choice.
Does it override origin
No. Varietal, terroir, processing and roasting all matter, and a great varietal grown badly is not great coffee.
