Therefore, by controlling the heat radiation from the leaf tobacco, the temperature of the leaf tobacco can be maintained at 70 to 100 ° C. without heating.
As specific methods for maintaining the temperature of leaf tobacco at 70 to 100 ° C. without heating, there are a method of storing leaf tobacco in a heat insulating container, and a method of using leaf tobacco by leaf tobacco.
The state of the leaf tobacco in the heat retaining step is preferably the above-described unpacked packaged tobacco, particularly preferably a packaged tobacco that satisfies all the following conditions (a) to (c).
(A) The volume is 0.1 m 3 or more.
(B) The density is 150 kg / m 3 or more.
