Decaffeination
Decaffeination is the process of removing most of the caffeine that naturally occurs in coffee. There are three methods of decaffeination: the solvent-water method, the Swiss water process method, and the carbon dioxide method. While chemicals are used to decaffeinate most coffee, the Swiss Water Process uses only water. Water decaffeination results in great tasting coffee. The use of chemicals could distort the true coffee flavor.

Drip Brewing
Drip brew is a method for brewing coffee which involves pouring water over coffee contained in a paper filter. Water seeps through the coffee, absorbing its oils and essences, solely under gravity then passes through the bottom of the filter. The used coffee grounds are retained in the filter with the liquid falling (dripping) into a collecting vessel such as a carafe or pot. Drip brewing is the most popular method of coffee brewing, owing to the overwhelming popularity of the automatic drip brewing coffee machine. There are, however, several manual drip-brewing devices on the market, offering a little more control over brewing parameters than automatic machines.

Dry Method
A coffee processing method that involves removing the husk or fruit after the coffee berries have been dried, also known as the Natural method. The result is often inferior to washed coffee or coffee that is wet-processed.
