Since diagrams help me understand, I found this:
Which shows 5 criollo primings, not 3. (I am ignoring the corojo primings shown on the right of the diagram, because quite frankly I have never seen these offered for sale on the websites I purchase from.) I assume that each leaf gathers strength as it occurs on successively higher points on the plant, and the "primings" are merely arbitrary lines drawn on a linear progression.
Now my question
when shopping to purchase leaf, should I be aware of what type of plant/country of origin the leaf is, or are all leaves sold retail to folks like us graded and packaged to a common standard, IE Volado is milder than seco is milder than visio.... etc.
Also, how come I never see corona leaf offered for sale?
Finally, Why are binder and wrapper leaves not identified by primings? Are they uniformly gathered from the volado priming?
