The concept for the Nub is based on the idea that the average cigar usually finds its sweet spot -- the part of the cigar that is most flavorful and balanced -- at the 3 1/2 inch- to 4-inch point of a cigar. No Nub is longer than 4 inches long. Oliva says Nub cigars are loaded with copious amounts of tobacco; some of the cigars are as thick as 66 ring gauge, or more than one inch in diameter. The large ring gauge not only produces abundant amounts of smoke, but consequently forms a dense ash which, Oliva says, insulates the cigar as it burns, keeping it cool and maintaining its flavors.
