What is Tunneling?
Tunneling is a term used to describe a cigar that burns unevenly, with the filler tobacco burning faster than the wrapper. This creates a tunnel-like appearance as the cigar burns, and it can negatively impact the flavor and smoking experience. Tunneling is often caused by improper construction, such as uneven packing of the filler tobacco, or by smoking the cigar too quickly, which causes the core to overheat. Smokers can prevent tunneling by taking slow, even puffs and ensuring that the cigar is properly lit at the start.
