Commercial tea blends are created by combining 20 to 40 different teas to achieve a consistent, high-quality product for the consumer. This practice serves several key purposes:

Consistency and Character: Blending allows producers to maintain a reliable flavor profile, ensuring that the tea tastes the same regardless of seasonal variations or specific harvest conditions. While many blends aim for a good average character, others are crafted to highlight specific traits, such as the pungency of Assam tea or the unique flavor of seasonal Ceylon tea.1
Economic Balance: Price is a significant factor in the blending process. Producers incorporate lower-cost teas, known as fillers, to balance the overall cost of the blend while maintaining the desired quality.1

By sourcing leaves from various estates and countries, blenders can effectively manage both the sensory experience and the affordability of the final product.1
