If you take a Camelia sinensis leaf and pour hot water over it, you’l get nothing from it. The leaf needs to be roughened up first in order to release its aromas and flavours when it comes into contact with water. Immediately after picking, the producer will process the leaves, which removes much of their moisture and eventually breaks down their structure without breaking the leaves themselves, so that the juices contained within their many cells can be extracted. This is one of the machines that’s used here in West Java (Indonesia). A cloth sack is packed with tea leaves then squeezed hard between two metal discs. This tool is widely used in Taiwan for making Oolongs, and is also used to make green teas that are rolled into balls.
