Here is the answer to his question
"Most of the ammonia released during aging or fermentation is created from the enzymatic breakdown of albuminous proteins.
Formulas of amino acids:

Proteins are made up of various amino acids. The structure of every amino acid (e.g. "amine containing acid") has one NH or NH2 component.
The amino acid serine.
When this nitrogen entity is released, it reacts with the hydrogen in water to form NH3, which is ammonia."
That scanned image above shows just how complicated it can get. You should be willing to do additional fermentation if needed.
If you all don't want to do the work to develop the relationship with the leaf to learn first hand what it means to make a cigar, then this might not be for you.
I hate to talk like this but I hate more to discourage anyone from doing something that could be so very gratifying.
My short spiel is know your leaf. I believe there is no substitute for the relationship building with the leaf.
Having to prepare leaf for cigar assembly in addition to what you buy I believe, is unavoidable.
A lot of what you'll get will be different as far as classification.
Meaning, caricature in body or weight / thickness, color, qualities like burn, aroma, taste. All which will determine what and how much preparation will need to be done.
I believe that the final preparations should not be done before the manufacturer. Because it would not store well.
In addition, there are things being done that manufacturers will not talk about. A master blender is not going to tell us his petuning method or recipes. They are there trade secrets.
I want leaf straight out of a bail. I don't want any additional handling being done that is not necessary. I want to be the one doing the final sorting and classifying.
I'm very happy to be able to get leaf that has been prepared properly for bailing.
Something else, curing, refers to color curing. Which gets the green out in the barn. Fermentation is a controlled composting.
