The higher-grown the coffee, the better. Arabica coffee is the only species that grows at higher altitudes. Coffee is classified by its relative density - the denser the finer. These beans have a higher concentration of complex sugars.
3 factors that contribute to these complex sugars:
- Harsh growing conditions - this helps to slow the bean's maturation process allowing ample time for complex sugars to develop.
- Mountain Drainage - drainage down the mountains reduces the absorption of water. This results in higher concentrations of flavor.
- Less probability of disease - a lower number of plants grow at higher altitudes because of the harsh conditions. The space between each plant is greater, helping to reduce the spread of disease.
