I think the "blond/brun" classification is too limited, when I begun learning more about tobacco, I didn't understand why in France we only talk about these two types...Thanks for reply, yes, blond and brun is sufficient, the others are possibly over-classifying it. For example I never understood why to divide tobacco plant into five different qualities of the leaf when Low, middle and top seem enough. Don't think I am a French tobacco fanatic, i am satisfied with any dark rolling tobacco. With me it is not problem of variety but of processing tobacco, If I learn how to do it well, I can make good rolling mixture with varieties I have (Adonis, Gooose Creek Red, Tabaco Negro, some fire cured and oriental to make the taste more interesting). Yesterday i mixed 10g of GCR low leafs, 20g of GCR mid Leafs, 10g of Adonis mid leafs, 20g of Balikesir top leafs and 10g of my fire cured, the result is smokable.
I see that you are from Italy, I was collecting lighters, Italian Saffa lighters from 30s were one of my favourites. I have three from this manufacturer, Classic lift arm, smaller version for ladies and Saffa Aksum with wind shield, nice work.
The separation of leaves depending on their position on the stalk is mostly over detailed for commercial manufacturers. For us small growers, we don't need to have as many "stalk positions", it's all up to you
P.S. I am from France, @Alpine is in Italy, he might know better about the lighters
