A Culebra cigar is a fairly unique type of cigar or better said three cigars wrapped into one. According to Tobacconist University:
Spanish for “snake”, culebras are probably the most unusual cigar(s) to behold. The culebra is actually 3 individual cigars braided together and then bound with string. These cigars were developed as daily rations for Cuban torcedores. Traditionally, factories have allowed their rollers a daily ration of cigars; but managers had little control over how much one person could consume. The culebra is an underfilled cigar that retains its rustic “snake-like” shape after it has been unbraided. This visible hallmark gave managers an ingenious method to ration and control employee consumption.
This type of cigar was designed to somewhat limit the amount that torcedores can take home every day.
According to various theories found online, the fear the Tobacco Plant Manager had wasn’t actually how much the individual enjoyed that day, but rather him or her taking a few home every night to sell to others in the neighborhood. Rollers could take home 3 cigars a day, they were twisted so they wouldn’t be taking home cigars that could be resold (somehow we don’t believe that stopped them).
It is actually quite a historical cigar. Some individuals separate them into their three distinctive cigar units, others have all three at once. There really is no rule on how to have this type of cigar.
