3/16 Tubing Resources

In 2013, we received a Working Lands grant from the State of Vermont to transition our sugarbush to 3/16-tubing, which allows for a natural vacuum system. By making this transition, we were able to eliminate the traditional vacuum pumps that many modern sugaring operations rely on. Ours was the first commercial scale implementation of this experimental system in Vermont, and Art continued to conduct research and implement improvements into this method through Spring 2022. Most recently, he focused on sanitization methods for 3/16 tubing. Art was always happy to share his findings with other sugarmakers. We have compiled his writings, videos and other resources here.
