IAPAR 59 was developed by the Paraná agronomic institute in Brazil from Sarchimor material.
Where it spread
Well beyond Brazil. It is planted in Central America, and it is one of the varieties behind the specialty replanting in Yunnan and elsewhere in Asia.
The cup
Clean and sweet with a medium body and moderate acidity. Dependable rather than distinctive, and clearly better than the Catimors it often replaces.
Why it traveled
Good rust resistance, good yield, a compact habit, and adaptability to a wide range of conditions. For a national program choosing a variety to promote, those matter more than a competition score.
Brewing it
Filter or espresso at medium roast.
Sarchimor and Catimor
Both families take their rust resistance from the Timor hybrid, a natural arabica-robusta cross. Catimors use Caturra as the arabica parent, Sarchimors use Villa Sarchi. Sarchimor selections such as IAPAR 59, Parainema and Obatã are generally reckoned to cup better than early Catimors, though growing altitude and processing matter more than the family name.
On the label
Roasters rarely name it except on single-farm lots from Brazil, Central America or China. The institute behind it has since merged into IDR-Paraná, but the variety keeps the IAPAR name.
