Corona Cigar has had several "American" cigars using Florida Sungrown tobacco. I'm a big fan of FSG having gone through several boxes of what is/used to be a Drew Estate distributed cigar.
Their latest was the All American Experimental FSG that I smoked and enjoyed. Not sure how the JC Newman cigar is different but I'm fairly sure they are pretty similar and all iterations are either rolled at the J.C. Newman factory or JC Newman and one of the other smaller factories in Tampa,
If the price tag is an issue for the JC Newman cigar FSG is still available at a reasonable price. JC Newman makes some pretty good cigars and they tend to be more expensive. Only critisism I've read of the JC Newman cigar is it's price/value.
