The Brigham system was developed in response to a common complaint of pipe smokers - tongue bite. Brigham found the perfect taste-neutral and effective material in natural, untreated Rock Maple. Each distillator is made by hollowing out the inside diameter of a 3.5” Rock Maple dowel and pressure-fitting a special metal cap to its end to help the filter fit snugly inside the pipe while making removal simple. Consider that in most other pipes, smoke spends half of its time passing along a plastic or rubber channel which can add negative flavor to the smoke while providing no benefit of its own. This combination of reduced exposure to plastic and rubber, drastic reduction in tongue bite, elimination of gurgle and flow-back as well as ease of use has made Brigham Canada’s pipe of choice for generations. Of course, you can always use your Brigham pipe without the Rock Maple Inserts as well.
