Between you and Eric, you both hit my sentiments exactly on these. Hemingway anything does not age well at all. They just fade away. (Sweethearts are Hemingway blend rolled by apprentices.)
My hope in jar-storing was to halt the inevitable downfall of these cigars. I managed to hold their demise back from a year to about two years in jars, then they just went to hell just like they do in the humi in 8 months.
Where the essence goes, I have no idea. That's a whole nother discussion.
If this single experiment yielded anything, it's "If you like your Sweethearts, buy them and smoke them up". Same goes for the rest of the Hemingways.
I've gone through lots of Hemingways over the years and watched them fall off if I don't get to them right away. This just wraps that up.
Off topic, but if you want to smoke the worst cigar you've ever smoked in your life, try a three or four year old Curly Head. Be careful though, it's liable to make you abandon the hobby.
