Quarter-Inch Tubing: Is it a Better Option for Gravity Sap Collection?

Ten years ago, 3/16” diameter tubing was introduced to the marketplace as an alternative tubing to 5/16” diameter tubing.  However, recent research shows that sap production in 3/16” tubing drops off as soon as the second year after installation due to microbial growth. A replacement for 3/16” diameter tubing in gravity systems could be 1/4” tubing. With almost twice the aperture of 3/16” tubing (0.049 sq inches compared to 0.0275 sq inches), 1/4″ inch tubing is less likely to plug from microbes yet is still able to create a full column of sap for gravity vacuum. Quarter-inch tubing is currently not available for maple producers but can be procured from other industries and, with modifications, will work for maple production.

Expert Tubing Tips for Maple

At Leader’s Spring Open House, three top experts in tubing and woods management – Glen Goodrich, Mark Erlsten, and Jon Rybkiewicz – sat down for a little over an hour and shared loads of invaluable information on all aspects of installing tubing, tapping trees, and best woods practices.

North American Maple Syrup Producers Manual, 3rd Ed.

Since 1958 the North American Maple Syrup Producers Manual has served as a basic reference source for the production of pure maple products. This 2022 edition provides up-to-date, science-based information and recommendations relating to all aspects of the industry. The guidelines presented will help users ranging from the hobby and beginning producer level to those well-established in the industry. In addition, the information herein will benefit foresters, land managers, Extension and outreach personnel, and others aiming to provide assistance to those in the maple industry. Numerous photographs, tables, a glossary and hyperlinks to selected source materials are included.

This publication is also available in print, at www.mapleresearch.org/ordermanual.

Getting Started: Value-Added Products

The objective of this document is to provide guidelines for producing and selling packaged value-added maple foods and beverages. This document does not include regulatory requirements for unpackaged products sold at fairs or farmers markets. State and federal regulatory requirements are established to protect the producer and consumer from food safety concerns.

Management Strategies for Invasive Plants in the Sugarbush

There are multiple approaches to treat or otherwise kill invasive plants that that the maple producer wants to control. The best treatment in one situation may not be best in another situation. Methods of treatment are typically either mechanical or chemical. Both methods have advantages and disadvantages depending on the circumstances.

Maple Management

These Maple Management pages include a variety of educational resources related to business for current maple producers, prospective maple producers, and forest land managers. Includes annual cost of production analyses, legal resources, business resources, rental and pricing tips, and more.

Why and How to Check your Hydrometer’s Accuracy

Hydrometers are a critical tool for making high-quality, legal density maple syrup. A $20 to $30 investment in an accurate hydrometer can yield a valuable return in income for the producer. This article explains how to use and test a hydrometer for accuracy.

Reduced Sap Yields When Tapping Into Non- Conductive Wood

According to a recent survey of more than 300 maple producers in the northeast United States, nonconductive wood was hit during tapping on average 4.5% of the time and the responses ranged from 0-41% of the time (UVM Extension 2019 unpublished). Previous research has explored factors that impact the likelihood of tapping into NCW. Significant factors include but are not limited to; dropline length, taphole diameter, tapping intensity (number of taps/tree) and stem growth (van den Berg and Perkins 2014). Other work touched on the relationship between the amount of conductive wood exposed while tapping and yields (Wilmot et al. 2007). But to date, there has been no direct investigation as to the relationship between the percent of NCW is intercepted while tapping and sap yield. The present study sought to understand the relationship between the amount of NCW in a given tap how and the amount of sap collected, as well as understanding if other factors (sap sweetness) might impact total yields between treatments.

Managing Invasive Plants in the Sugarbush

The history of introduction of invasive plants into the US is varied, but there are many examples of species that have become interfering after introduction in the middle 1800’s. In most cases the introduction was intentional because of the expectation of a benefit for humans or wildlife. Following are several invasive shrub species common in many areas of the maple syrup producing region of North America.
