Reason One for Smoky Flavor in Pu'er Tea:
Tea leaves themselves may have a smoky flavor, or it may be caused by the processing method. Generally, if the smoky taste is not strong, it can fade over time. In some Pu'er teas, such a flavor can enhance the tea's quality and benefit its subsequent fermentation.
Good aromas are always pleasant and comforting. A smoky note that gradually fades with time, or one that brings a sense of comfort during tasting, can be considered acceptable.

Reason Two for Smoky Flavor in Pu'er Tea:
The other type of smoky flavor is an undesirable off-flavor, also caused by processing methods or storage conditions. This kind of smoky taste is usually pungent and irritating to both the nose and the palate, with little room for improvement.
Poor "off-flavor" smoky notes, besides being strongly irritating, often have a numbing or stimulating effect on the taste buds and oral mucosa. Therefore, when purchasing Pu'er tea, consumers should choose high-quality products to avoid teas with unpleasant smoky flavors.
