Want to get a good sense of a cigar all at once? Try retro-hailing. In simply terms, retro-haling is when you move smoke from the back of your mouth, up through your sinus and out through your nose. By practicing this smoking technique, you will be able to taste and smell a cigar’s spices, body, flavor and strength in a single puff. You might have to try it more than once before you get it right, though.
