The main difference between hand-rolled and machine-made cigars is the amount of human labor involved in their production. Hand-rolled cigars are made entirely by hand, with each cigar being carefully crafted by a skilled roller. This involves selecting the right tobacco leaves, cutting them to size, rolling them into shape, adding filler tobaccos, and finally wrapping it all together with a wrapper leaf. Machine-made cigars are mass produced using automated machinery that cuts down on labor costs but sacrifices some of the quality found in hand-rolled cigars. Machine-made cigars tend to have more uniform sizes and shapes than their handmade counterparts due to the use of molds and presses during production. Machine-made cigars usually contain less expensive filler tobaccos than those used for hand rolled cigars.
