Tea grades are a way of categorizing tea based on factors such as leaf size, quality, and processing method.

Whole Leaf Grades: These grades typically consist of the highest quality tea leaves, which are picked when they are young and tender. Whole leaf grades include Orange Pekoe (OP), Flowery Orange Pekoe (FOP), and Tippy Golden Flowery Orange Pekoe (TGFOP). These teas are prized for their delicate flavors and aromas, and are often more expensive than lower-grade teas.

Broken Leaf Grades: These grades consist of larger pieces of tea leaves that have been broken or crushed during processing. They include Broken Orange Pekoe (BOP), Flowery Broken Orange Pekoe (FBOP), and Golden Broken Orange Pekoe (GBOP). Broken leaf grades are generally less expensive than whole leaf grades, but can still offer excellent flavor and aroma.

Fannings: These grades consist of smaller, finer particles of tea that have been sifted out during processing. Fannings are commonly used in tea bags and are often less expensive than whole leaf or broken leaf grades. They can offer a strong, robust flavor but may lack the nuanced flavors and aromas of higher-grade teas.

Dust: These grades consist of the smallest particles of tea, which are often leftover after processing. They are also commonly used in tea bags and are the least expensive type of tea. Dust grades can offer a strong, bold flavor but may lack the complexity and depth of higher-grade teas.

Tea grades can be a helpful guide for understanding the quality and characteristics of different types of tea. While higher-grade teas may be more expensive, they often offer a more nuanced and satisfying drinking experience, while lower-grade teas can still be a great option for those on a budget or looking for a strong, bold flavor.
