Characterizing maple sap flows
Individual sap flow events are highly variable and dynamic, ranging from slow, weeping flows that last for days to short bursts of high flow that last for only a few hours.

Bark removal and taphole closure with arc-barb spouts
The Arc-Barb Spout (UVM Patent Pending) is designed with a shortened barrel to allow improved sap flow from the shallower, more productive sapwood zones in maple stems.
Drop and spout sanitation review
Considerable research has been conducted by the Cornell Maple Program and University of Vermont Proctor Maple Research Center on the effects of spout and tubing sanitation on improvements in sap yield and economics.
Cost of hitting stained wood when tapping
Avoiding tapping near previous tapholes is a common practice in maple production. This is because previous wounds create a zone of stained wood that extends slightly wider and deeper than the taphole, but extends upwards and downwards, often reaching 6-12 inches in length in each direction, affecting a volume of wood approximately 50 times (range of 15-150X) larger than the volume of the taphole (vanden Berg et al. 2023).
Update on Plantation Maple Research by UVM
For several years researchers at the UVM Proctor Maple Research Center studied the feasibility of collecting sap from saplings as an alternative production method for maple syrup.
Maple Sports Drink Fills a Niche in Performance Beverage Market
The Cornell Maple Program has been working on developing athletics-oriented maple products for several years. Our latest work has led to a “maple sports drink,” a hydrating, nourishing electrolyte-replacement beverage that meets the same nutritional standards as Gatorade and Powerade.
Gourmet Maple Marshmallows – A New Recipe & Guidelines
The Cornell Maple Program has been working on adapting gourmet marshmallow procedures for a recipe that uses maple as the only sweetener, and the results pack a lot of maple flavor.
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.
Why sap may not always flow well in early season
Maple producers know that when the temperature starts to rise in the spring, sap flows can’t be far behind. But when the weather starts to warm early in the spring and temperatures seem favorable for good sap flows, they are sometimes left wondering why the sap hasn’t started to run. There are several explanations for the disconnect between warm air temperature and a lack of flow during
the early season.

Explains how sap flows in trees and the impact that tapping has on subsequent years’ sap flow.
