The quality of spice raw materials plays a decisive role in the final presentation of aroma. These raw materials are essentially medicinal herbs, so it is crucial to select high-quality varieties from each production region—whether from the Tibetan Plateau, the Gobi Desert, tropical jungles, or the Erhai tea villages, the core standards are authenticity of origin and superior quality.
The prices of spice raw materials vary greatly. Take osmanthus, for example: ordinary quality sells for about 50-60 RMB per kilogram, while high-quality osmanthus can reach 200-300 RMB per kilogram. The higher prices of premium ingredients are due to meticulous selection and scientific drying processes that preserve their true flavor to the greatest extent.
My favorite fresh danshen, I personally wash and sun-dry it. This allows me to control the quality of the raw materials throughout the process, as well as effectively avoid impurities, pests, and other issues that could affect the purity of the aroma, ensuring that every batch of material meets the strict standards for incense making.
