Knowing how to properly maintain your sugar bush — a maple producer’s most valuable resource — is a critical skill.
Occasionally, maple syrup becomes contaminated with floating masses or surface mold. Conventional practices have been to discard obvious mold growths, re-boil and then consume the syrup. This practice may be risky, especially with the increasing number of food borne illness outbreaks with other food products and the resulting negative publicity surrounding these outbreaks.
The range of sugar maple (Acer saccharum Marsh.) is expected to shift northward in accord with changing climate. However, a pattern of increased sugar maple abundance has been reported from sites throughout the eastern US. The goal of our study was to examine the stability of the sugar maple southern range boundary by analyzing its demography through the southern extent of its distribution. We analyzed changes in sugar maple basal area, relative frequency, relative density, relative importance values, diameter distributions, and the ratio of sapling biomass to total sugar maple biomass at three spatial positions near the southern boundary of the speciesÕ range using forest inventory data from the USDA Forest Service Forest Inventory and Analysis program over a 20 year observation period (1990Ð2010).
Preventing mould in packed maple syrup can be a challenge. Cold-packing syrup usually guarantees mould will grow in bottled containers and can impart off-flavour in the syrup. Maple researchers at the University of Maine and at Carleton University in Ontario are investigating whether current hot packing recommendations require refinement to preserve quality and prevent mould in syrup.
Though it is not well known, all species of walnut (Juglans spp.) produce a sweet sap that can be boiled down into valuable syrup. There is a well-established resource of black walnut (Juglans nigra) trees throughout eastern North America that could be utilized for syrup production to complement existing sugaring operations.
Results of an annual survey conducted of New England sugarmakers, capturing information on production practices and results, such as types of equipment used, sap sugar content, sanitation practices, and other data.
Cornell University’s Maple Specialist, Steve Childs reviews a second reverse osmosis system for a small-scale maple syrup producer. Reverse osmosis greatly reduces the time and energy spent in boiling maple syrup by pulling much of the water from the sap before the boiling process begins. Sap can be put through the system repeatedly and becomes more concentrated with each pass through the RO membrane. Boiling the concentrated sap at the end is always necessary however, as that greatly contributes to maple syrup’s rich flavor.
Cornell University’s Maple Specialist, Steve Childs, reviews one more reverse osmosis unit that is still applicable to the small-scale maple producer, despite this unit’s size.
For several years, PMRC researchers conducted research on the collection of sap from small-diameter maple trees. This document outlines the basic concepts, techniques, and applications of this type of sap collection.
