A lot of truth in this and I think the biggest aspect for me was my palate. I've been smoking cigars for over 30 years, with Cubans for over 15 years now. For a long time it was hard for me to describe what my palate was tasting and putting it in words. This took a LOT of reading, learning (here) with reviews and visiting Cuba 5 different times. Not saying visiting Cuba is a prerequisite, but it sure helped me knowing from the ground up why CC's taste as good as they do. This by visiting several farms, factories and talking to these experienced cigar makers and learning about "blending" allowed me to at least have some knowledge what I am tasting and the why's of what I'm experiencing in these wonderful CC's.
P.S. ... I am still learning and that will never end during my journey of cigars. This may stop when I'm popping up daisies, but I sure as heck hope I'm constantly smoking a Partagas GR up in the heavens!
