Grading of tea leaves

Firstly, the grades of tea vary according to the country of origin and are not standardised worldwide. The grades do not take in to account external factors, such as the climatic conditions of the region, soil quality, storage, etc. The grading of leaves simply indicates the different sizes of leaves and is a visual descriptor of sorts (example the "tippiness" of the tea in a lay man’s definition is the percentage of unopened leaf buds in the tea). This is important to understand that it means grade does not necessarily mean good flavour or quality. It is usually a measure of how good the leaf looks after the last stage of production.
