Tobacco grading method:

The classification method is generally divided into "classes" first, then into "groups", and finally into several different "grades" according to the quality of each group of tobacco leaves. In terms of grading standards, groups and series in different countries vary greatly, but the basic principles of grading are still relatively consistent. For example, when Zimbabwe's flue-cured tobacco is graded, it is divided into eight leaf groups according to some characteristics of appearance, namely upper leaves, top leaves, middle leaves, lower leaves, bottom leaves, mature leaves, lower loose leaf groups and upper loose leaf groups, and then divided into several subgroups according to different colors.

After being divided into parts and colors twice, each group was divided into several grades according to the scoring factors, with a total score of 1225. The main grouping factors are location, color and thickness. The scoring factors are various and not uniform, but they are all based on the principle of "what seems to be the same".
