Calabash Style
The original Calabash Pipe, made from African Gourds, was popularized in Britain during the 1800s.  The Gourds are trained by hand, while they grow, to attain the perfect "S"-like shape for Pipe making.  This process, and the large volume of space within the Gourd, creates a shape that provides a cool smoke.  Because the Gourd cannot sustain extreme heat, Calabash Pipes typically have a removable Bowl insert (Briar, Meerschaum, Ceramic, etc...) for the tobacco to be placed in.  Today, the term “Calabash” refers to any Pipe in the classic Gourd "S"-like shape.
