The transformation of coffee cherry to a green coffee bean is a complex biotechnological process. The process involves fermentation where microorganisms (yeast, bacteria and fungi) use the mucilage in the coffee cherry digest the carbohydrates and produce complex metabolites. These metabolites when roasted provide the wonderful aroma and taste of a cup of coffee.
In this very special lot we took fresh coffee cherry from the Zilli and Sampieri families, pulped them carefully, and added a starter culture to the fermentation tank. We allowed the fermentation to extend about two to three times the normal fermentation while monitoring the pH and other indicators. Finally we washed the coffee and dried it. The secret behind our starter culture is that it changes the microbiological makeup of the fermentation to both encourage good flavour and discourage the negative flavour elements. Hence when evaluating our coffee we found that the extended submerged fermentation using a starter culture enhanced the fruity and sweet attributes and reduced unfavourable volatiles, resulting in an improved aroma.

History of Coffee in Mexico
With seeds from the Caribbean, cultivation began in Veracruz, where custom house records indicate a few hundred bags of coffee were exported as early as 1802. But these exports were apparently anomalous because after 1805 coffee would not be exported again for twenty years, after the war of independence. Production did increase over this period, presumably for domestic trade and consumption. In 1817, a planter named Don Juan Antonio Gomez started “intensive cultivation” further south, where coffee thrived at high altitudes. By 1826 there were half a million trees in Cordoba and Mexican coffee was being exported. In 1828, seeds—or possibly plants—from Arabia (Yemen) were planted in Uruapan, near the Pacific coast west of Mexico City, by Jose Mariano Michelena. Trees were brought from Guatemala to be planted in the southern state of Chiapas in 1847, and Oaxaca would become the third largest producer of Mexican coffee by 1889.
Growing Coffee in Mexico
Mexican coffee grows in 15 states throughout the southern half of the country but over 90% comes from four states: Veracruz, Oaxaca, Chiapas, and Puebla. Specialty coffee comes from the highlands of Veracruz on the gulf coast, the mountains of Oaxaca and Chiapas at the southern tip of Mexico. In Veracruz coffee grows from 1,100-1,660 m.a.s.l. In Chiapas coffee grows from 1,300-1,700 m.a.s.l. In Oaxaca coffee grows from 900-1,650 m.a.s.l. Coffee is grown by more than half a million farmers, 95% of these being smallholders cultivating less than three hectares and 85% of Mexico’s coffee farmers are indigenous Mexicans. Most Mexican coffee is grown under shade and Mexico is one of the world’s largest producers of certified organic coffee and Fair Trade coffee. Most Mexican coffee is Bourbon, Catura, Maragogype, or Mundo Novo, though other varieties can be found. Mexico grows almost no Robusta.
