Tea leaf processing methods for the six most common types of tea. Tea processing is the method in which the leaves from the tea plant Camellia sinensis are transformed into the dried leaves for brewing tea. The categories of tea are distinguished by the processing they undergo.
ISO 3103 is a standard published by the International Organization for Standardization (commonly referred to as ISO), specifying a standardized method for brewing tea, possibly sampled by the standardized methods described in ISO 1839. [1]
Crush, tear, curl (sometimes cut, tear, curl) is a method of processing tea leaves into black tea in which the leaves are passed through a series of cylindrical rollers with hundreds of sharp teeth that crush, tear, and curl the tea into small, hard pellets. This replaces the final stage of orthodox tea manufacture, in which the leaves are ...
Common processing methods of tea leaves. After basic processing, teas may be altered through additional processing steps before being sold [88] and is often consumed with additions to the basic tea leaf and water added during preparation or drinking. Examples of additional processing steps that occur before tea is sold are blending, flavouring ...
The United States Food and Drug Administration tested tea until 1996.. Tea tasting is the process in which a trained taster determines the quality of a particular tea. [1] Due to climatic conditions, topography, manufacturing process, and different cultivars of the Camellia sinensis plant (tea), the final product may have vastly differing flavours and appearance.
Steeping, or brewing, is the process of making tea from leaves and hot water, generally using 2 grams (0.071 oz) of tea per 100 millilitres (3.5 imp fl oz; 3.4 US fl oz) of water or about 1 teaspoon of green tea per 150 millilitres (5.3 imp fl oz; 5.1 US fl oz) cup. Steeping temperatures range from 61 °C (142 °F) to 87 °C (189 °F) and ...
Fermented tea (also known as post-fermented tea or dark tea) is a class of tea that has undergone microbial fermentation, from several months to many years.The exposure of the tea leaves to humidity and oxygen during the process also causes endo-oxidation (derived from the tea-leaf enzymes themselves) and exo-oxidation (which is microbially catalysed).
Green tea leaves steeping in a gaiwan (type of tea cup) Steeping is the soaking of an organic solid, such as leaves, in a liquid (usually water) to extract flavours or to soften it. The specific process of teas being prepared for drinking by leaving the leaves in heated water to release the flavour and nutrients is known as steeping.
