Blending (or recipe creation) is one of the important steps in the refining process of almost all teas, not just Pu'er tea. It involves processing a mixture of tea leaves according to a formula, using leaves from different origins, different qualities, or different sieve grades/levels from the same origin. This can highlight strengths and conceal weaknesses, balance highs and lows, thereby not only ensuring the tea's color, aroma, taste, and shape meet standards and guaranteeing product quality stability and consistency, but also producing products with more distinctive style characteristics. Blending is actually a form of excellent creation, similar in spirit to the "blending" process in liquor production.

Tea produced using pure material is processed from tea leaves grown within a very small specific area. It might have relatively prominent characteristics in certain aspects, such as aroma or taste, but its overall harmony often has certain deficiencies. Additionally, due to the limited geographical production of the raw material, it is difficult to ensure long-term quality stability.

It can be said that "pure material is a relative concept, while blending is an absolute concept in tea processing." Therefore, it is incorrect to say that pure material tea is better than blended tea. Some manufacturers, lacking blending capability and sufficient reserves of various raw materials, excessively emphasize pure material to drive up tea prices. This is not a concept truly worthy of promotion.
