The University of Vermont Proctor Maple Research Center and the Cornell Maple Program Arnot Forest conducted a multi-year study examining several common sanitation strategies and assessing the effects on sap yield, attendant costs, and resulting net profits. The following graphs briefly summarize the results of this work.

This model estimates the proportion of clear, conductive wood in the tapping zone of an individual tree each year (for 100 years) based on the values input for tree diameter, tapping depth, spout size, number of taps, and dropline length. This is equivalent to the chances of tapping into conductive wood in this tree each year Ð if 80% of the wood in the tapping zone is conductive, you have an 80% chance of hitting conductive wood when you tap that tree. The model can be used to estimate whether various tapping practices are likely to be sustainable. A more complete description of the model and guidelines for its use can be found in the companion technical report “A Model of the Tapping Zone”, which is available on the UVM-PMRC website (http://www.uvm.edu/~pmrc).
In the Spring, maple trees begin to move sap up from their roots. At the Arnot forest, this sap is collected and then boiled down to produce maple syrup. In this video, Prof. Brian Chabot, tells us about the process and we see how maple syrup is made.
Cornell University’s Maple Specialist, Steve Childs, offers this video series for beginning sugarmakers.
Analysis of the importance of slope on a variety of tubing systems.
Why are my tapholes leaking and what can I do about it? (Part 2) Being able to recognize what is really a leak and what is not takes some time and thought and experience. This article offers some tips.
Tips for designing tubing systems and tapping
Why are my tapholes leaking and what can I do about it? (Part 1) There are often several issues involved in leaking tapholes, and sometimes the applied remedy itself turns out to be the actual problem.
Should I use 3/16″ or 5/16″ tubing? One of the first questions maple producers face when deciding to tube (or retube) a sugarbush is whether to use 3/16″ or 5/16″ tubing. This article explains some of the general rules that can be helpful in narrowing down the pros and cons of each approach.
There has been a lot of interest in 3/16″ tubing over the past several years. This article describes research results and possible future directions.
