Regardless of the availability and guidance provided, maple producers should clearly understand that the use of isopropyl alcohol in maple tubing systems anywhere in the United States is a violation of federal law.
Evaluation of wireless system to monitor vacuum in subing systems.
The amount of sap that can be extracted annually from trees for maple syrup production using current equipment and practices is more than double the typical yields achievable when current maple industry tapping guidelines were developed. The growth rates of trees tapped with these Òhigh-yieldÓ practices at 18 sites in Vermont were measured and evaluated to determine whether they were sufficient for the replenishment of conductive wood to remain at sustainable levels when current tapping guidelines are followed.
This research shows the trends in bulk syrup prices in the U.S. and Canada between 1998 and 2015.
The purpose of the present experiment was to test the precision of a variety of digital refractometers available to maple producers. Additionally, the effect of temperature on refractometer accuracy and precision was investigated, in order to assess the reliability of the automatic temperature compensation feature now present in the majority of refractometers.
This research shows trends in sap yield in US states and Quebec from 2001-2014.
Between 2008 and 2011 we conducted a series of controlled experiments performed with commercial maple equipment to investigate the potential effects of the use of RO on the composition, properties, and flavor of the maple syrup produced.
In 2014 and 2015 the focus of the tubing and taphole sanitation research changed dramatically. Tests conducted in 2013 showed that if the spout and drop line were adequately sanitized sap yield comparable to a new spout and drop could be obtained. With the assistance of a grant from the Northeast Sustainable Agriculture Research and Extension program of the USDA and in cooperation with the Proctor Maple Research Center in Vermont, a variety of spout and drop cleaning and replacement options were tested to determine the extent of sap yield changes.
Near the end of each sugaring season, producers must make a decision when to stop making maple syrup. Sometimes the decision is an easy call, such as when the onset of bud break and cessation of sap flow coincide. The decision to stop production can also be the result of careful economic analysis of the cost of production versus value of the product. The variable costs (fuel, labor, filters, etc.) of any maple operation are a key component to this sort of analysis.
One of the many off-flavors that can be found in maple syrup is metabolism, often compared to the taste of wet cardboard or ‘woody.’ This article explains metabolism and how to identify it.
