The materials used in “云烟（5mg印象）” are sourced from the leaves of the Impression Tobacco Estate, where each premium leaf is hand-selected by skilled artisans, with only one-eighth of the essence retained from each top-quality leaf. The tobacco is aged in oak barrels, akin to the process of winemaking; this aging process reduces the harshness and off-flavors of the tobacco. The formula of “云烟（5mg印象）” uniquely incorporates concentrated blackberry juice, enhancing the comfort of the flavor while making the aroma more delicate and smooth. It is also blended with concentrated sour cherry juice, effectively softening the smoke, improving the taste, ensuring good harmony, and adding a sense of naturalness.
