"Water pressure is one of the most                              important factors which influences in                     the final quality of espresso coffee"                             (Andueza, et al)

           There are two major kinds of coffee that                 are produced in the world. Coffea arabica             and Coffea robustas.

  • Coffea Arabica: grows best in altitudes from 1500 to 1600 feet, and in environments that are like the subtropic regions. While this coffee is the most popular coffee bean, it is very difficult to grow. It also has a tastier bean.
  • Coffea Robustas: grows best in altitudes from sea level to 3200 feet, and does good in areas with higher temperatures and higher humidity levels. Of the two C.Robustas is the least popular, but is must less picky to grow. While this bean is less tasty than the C. Arabica, its bean has higher caffeine quantities.
