The outermost rings of wood in maple trees have the highest sap flow rates and have sweeter sap than the wood found deeper in the tree. We designed a spout that incorporates both a shortened barrel and a series of barbs along the shaft to anchor the spout tightly within the wood and bark tissues.
Ongoing research at the University of Vermont Proctor Maple Research Center over the past thirteen years has examined a variety of approaches to increases yield from 5/16” maple tubing systems on vacuum.
We occasionally hear the question: “Even if the season is late or short, shouldn’t there be the same amount of sap produced during the time that does run than there
would have been if it were longer season or happened at ‘the usual’ time?”
Maple sap tubing collection systems have undergone continuous evolution since being introduced. Over the past several decades, spouts in particular have changed considerably, with a marked shift towards smaller (1/4”, 19/64”, or 5/16”) spouts, developed and introduced by CDL.
This collection of 13 videos from UVM Proctor Maple Research Center includes topics ranging from invasives to regeneration to culverts.
This research is focused on a first of its kind survey of professional foresters with the goal of not only understanding the technical approaches foresters use when working in sugarbushes, but also how the surveyed foresters view sugarbush management compared to managing stands for other forest products.

This aim of this project was to determine whether early spout and dropline deployment before tapping could be used while maintaining good sanitation levels and high sap yields.
We regularly get questions from maple producers about which defoamers are the best to use. Of course, the answer is…it depends.
During the 2021 season, the UVM Proctor Center tested SapSpy (www.sapspy.com), a relatively new entrant in the sugarbush monitoring field.
