Thanks Steve,
Tried the link - no joy. Even tried going to www.nature.com and searching - again, no joy. Not that I doubt the info, but developing a test in a year is pretty quick. Also, how would you test the acid content of the various tobacco strains in all of the Cuban regions and specifically for tobacco that may be 40 years old and come up with a definitive "acid signature"? Does the signature vary from region to region? From different spots on the same plant? From plant to plant? I would have to really look into the methodology. Perhaps a DNA related test, but then again, that would be expensive and not easy to accomplish in just a year. I'd really need to see the entire content of the research paper to determine its validity. Having done research, there are a lot of variables to be suspicious of.
Nevertheless, your last comment is true. Good smokes are a luxury to find - and these are exceptional, regardless of the content.
I was just curious about anyone else having tried them. The aroma and taste are reminiscent of the Cubans I've tasted in the past.
Any other opinions or info?
