There are several reasons for this. 9 times out of 10, when I encounter a plugged cigar, it is because they are fresh. Cuban cigars are made to age. Many times I’ve had plugged cigars from a box, and just put it away for several years, and they (most of the time) smoke perfect when I try them again. There is nothing worse than a cigar that is too loose. They smoke very hot, and taste pretty bad, the rollers know this and anticipate the tobacco shrinking over the years. Another problem may be the humidity. Tobacco swells when too wet. Some cigars need dryboxing for a while to remove the excess moisture. Last, and certainly not least, get a perfect draw tool. I probably use mine every 3 to 4 cigars, even if it’s just to ease the draw a little bit.
