SapSpy keeps tabs on the sugarbush
During the 2021 season, the UVM Proctor Center tested SapSpy (www.sapspy.com), a relatively new entrant in the sugarbush monitoring field.

Should droplines be replaced when using check valve adapters or spouts?
Since check valve adaptors and spouts reduce sap backflow, this research studied whether or not dropline replacement is as important to improving sap yield when using these taps.
Should Lateral Lines Be Vented?
A great deal has changed since the 1960s and 1970s in terms of maple production and recommended practices, especially given the introduction of the new polyethylene tubing formulations and new types of spouts. Consequently, we are occasionally asked whether lateral lines in gravity tubing installations should be vented. As a result of these questions, we compared sap yield from standard non vented (closed) 5/16″ lateral lines alongside a vented 5/16″ installation under gravity conditions.
Some quick tips to achieve higher sap yield
Increasing the yield of sap from maple trees is the goal of most maple producers. While getting there isn’t a matter of one simple thing, by
following best management practices and paying attention to detail it is possible to increase sap yields, often quite dramatically. Includes links to videos.

Sugar Profiles of Maple Syrup Grades
Although many analyses of the chemical composition of maple syrup have been conducted, relatively little information exists on the differences in composition of the individual syrup grades. As a first step in acquiring this information we performed a study to determine the characteristic sugar composition of each maple syrup grade.
Sulfite Concentration in Pure Maple Syrup
Maple syrup is a natural product free of artificial coloring or other additives. Regardless, some publications mention that maple syrup may contain sulfites. In this study, which is conducted by Center ACER in collaboration with UVM Proctor Maple Research Center, direct measurements of sulfites concentration in maple syrup samples collected during 2011 and 2012 were made.

Tapholes: Straight or Slanted?
Is there any difference in sap yield when tapping at a slight angle (the historical recommendation) or tapping straight in (the current recommendation)? While there might be other considerations suggesting that tapping straight in is advantageous, from a syrup yield perspective, there is no apparent difference.
Tapping guidelines for current sap collection practices
Research into whether existing tapping guidelines are appropriate to use with ‘high yield’ sap collection practices which remove a much greater amount of a tree’s sap than older systems.
