A tea whisk, often referred to as a chasen, is a traditional tool used in the preparation of matcha, a finely ground green tea. Typically made from bamboo, the whisk features numerous thin prongs that help to aerate and froth the tea when mixed with hot water. This process creates a smooth, creamy texture essential for enjoying matcha. Using a tea whisk is an important part of the Japanese tea ceremony, where the preparation and serving of matcha is a ritualistic practice. The whisk allows for the even distribution of the tea powder, ensuring a well-blended drink that highlights the unique flavors of the tea.
