Black Walnut (Juglans nigra) is a tree to consider tapping, and Butternut (Juglans cinerea) has similar characteristics and can produce syrup. When considering tapping, however, it is good to understood that walnut trees and not just maples with compound leaves and big edible nuts. Walnuts have anatomical and physiological characteristics that affect tapping and syrup making.

This aim of this project was to determine whether early spout and dropline deployment before tapping could be used while maintaining good sanitation levels and high sap yields.
How to build a vacuum boiler to make high-quality granulated maple sugar.
We regularly get questions from maple producers about which defoamers are the best to use. Of course, the answer is…it depends.
In response to injury from wounds such as tapholes, trees initiate processes to compartmentalize the affected area in order to prevent the spread of infection by disease- and decay-causing microorganisms beyond the wound, and to preserve the remaining sap conducting system (Shigo 1984). This results in the formation of a column of visibly stained wood above and below the wound, and the affected zone is rendered permanently nonconductive to water and nonproductive for sap collection. These processes, along with effects from microbial activity, are responsible for the gradual reduction in sap flow from tapholes over the course of the production season. There has been recent renewed interest in strategies which attempt to extend the standard sapflow season or increase overall yields through the “rejuvenation” of tapholes. As part of a multi-year experiment to investigate the yields and net economic outcomes of several taphole longevity strategies, we conducted an experiment to investigate the volume of NCW generated in response to two of these strategies.
Maple production requires sugarmakers possess a diverse set of skills in order to tend the forest resource and maintain a productive sap collection system. Maintaining a healthy, diverse sugarbush that maximizes its growth potential requires periodic vegetation management activity. Also known as thinning, vegetation management is the process of reducing competition for light, water and nutrients of crop trees. Felling trees is the key activity in vegetation management and may be done by logging professionals in support of formal forest management plan objectives or by the sugarmaker or landowner on an as needed basis and including response to extreme weather events.
Maple producers know that when the temperature starts to rise in the spring, sap flows can’t be far behind. But when the weather starts to warm early in the spring and temperatures seem favorable for good sap flows, they are sometimes left wondering why the sap hasn’t started to run. There are several explanations for the disconnect between warm air temperature and a lack of flow during
the early season.
How does a tree respond to the wound created by a taphole, and what does that mean for future sap production?
Explains how sap flows in trees and the impact that tapping has on subsequent years’ sap flow.
Small reverse osmosis machines can be built from consumer parts and can help small producers cut down on boiling time and energy use. This article offers tips on building such devices.
