Ask Proctor: Tiny Bubbles
Maple producers using tubing often observe bubbles emerging from the tree within the spout or first few inches of tubing when the sap is running. If the spout is not seated properly, leaks may occur.T hese are most noticeable as rapidly moving streams of small or large bubbles. At other times, these are not leaks, however repeated or overly aggressive attempts at seating spouts to make the bubbles stop can create leaks that further attempts at spout seating will only make worse.

Ask Proctor: Why do I sometimes make light-colored syrup at the very end of the season?
The typical trend over a sugaring season is for syrup to start out light in color and get progressively darker, eventually ending up with very dark (and strong or off-tasting) syrup at the end. While there can be some temporary excursions up and down in syrup light transmittance, the natural progression is from light syrup early on to dark syrup near the finish. However, occasionally a syrup producer finds that right as the season is concluding the syrup color goes up dramatically and wonder why this happens.
Effect of spout deployment date and drop configuration on sap yield
Because of the lack of knowledge on this topic and the frequent questions we received about the proper practice, we implemented a study in the summer of 2022 to examine the single and interactive effect of spout deployment date and open verses closed drops on sap yield.
Sweet Talk: All Things Maple
This ongoing podcast features interviews with researchers and educators about topics related to maple production and marketing.
The Map of Maple: Off-Flavors
This tool is meant to identify off-flavors in syrup, and link the particular sensory experience to a specific defect and category that explains why the defect has occurred. Additionally, this tool serves as a user-friendly representation of the Vermont Agency of Agriculture Farms and Markets (VAAFM) “Maple Syrup Off-Flavors” manual.
The Map of Maple
The map of maple is a sensory tool, allowing you to explore all the wondrous possibilities of Vermont maple syrup. It offers some hints for tasting on your own.
Syrup with Saps
Business is booming if you own a commercial sugar bush! As forest managers, this means more and more of us are hearing from landowners interested in starting or maintaining a sugar bush. Unfortunately, if you are like us, you did not learn about maple syrup in forestry school. This episode’s guest, Mark Isselhardt, Extension Maple Specialist with the University of Vermont, helps us unpack the fundamentals of sap production, sugar bush management, and how the industry has changed in the 21st century.
Tapping guidelines for maple syrup production
Guidelines for tapping maple trees have existed for well over 100 years. Early tapping guidelines came about when buckets (gravity collection) were the only technology available for harvesting sap. New tapping guidelines are based on years of research into maple tree growth, sap harvesting practices/technology and a recognition that tree diameter alone does not fully explain all the factors that determine if tapping intensity in a given sugarbush is sustainable. This fact sheet presents sustainable tapping guidelines.
