Article: Wholesale tea merchants need to have a deep understanding of the processing techniques of tea leaves to ensure product quality. Roasting is an important process in tea leaf processing that can give tea leaves a special flavor and aroma. When roasting black tea and Longjing tea, it is important to be careful and meticulous to ensure the quality of the final product.

When roasting black tea, wholesale tea merchants need to combine processes such as roasting, killing green, rolling, and drying to produce high-quality black tea with a bright color and a rich taste.
