There are many ways a partnership between maple producers and brewers could be beneficial. The goal of this project was to focus on maple-flavored beer. Within this scope, there are many options including maple extract, fenugreek, maple syrup and maple sugar. We focused on the use of fenugreek, maple syrup and maple sugar for aroma and flavoring in this experiment.
A simple colorimetric test detects off-flavour profiles ofmaple syrups inminutes, which are detectable by the naked eye. As flavour profiles are due to complex mixtures of molecules, the test uses nonspecific interactions for analysing the aggregation and color change of Au nanoparticles (AuNPs) induced by the different organic molecules contained in off-flavour maple syrup. The test was optimal with 13 nm citrate-capped AuNPs reacting 1 : 1 with pure maple syrup diluted 10 times. Under these conditions, normal flavour maple syrups did not react and the solution remained red, while off-flavoured maple syrups aggregated the AuNPs and the solution turned blue. Different classes of molecules were then tested to evaluate the types of compounds typically found in maple syrups reacting in the test, showing that sulfur- and amine-containing amino acids and aromatic amines caused aggregation of the AuNPs. The test was validated with 1818 maple syrup samples from the 2018 harvest in Quebec and 98% of the off-flavoured maple syrups were positively identified against the standard taste test. Preliminary tests were performed on site in maple sugar shacks to validate the applicability of the test on the production site.
Is there any difference in sap yield when tapping at a slight angle (the historical recommendation) or tapping straight in (the current recommendation)? While there might be other considerations suggesting that tapping straight in is advantageous, from a syrup yield perspective, there is no apparent difference.
The compartmentalization (walling off) process in maple trees and how it affects how to tap for maple syrup production.
Maple producers sometimes have a difficult time locating areas on the tree that will produce unstained wood and good sap yields. This video suggests approaches maple producers using vacuum can take to counter this problem.
Best management practices to achieve high sap yields when tapping maple trees.
Techniques to manage spout and dropline sanitation in 5/16″ vacuum tubing systems for high yield maple production.
Our objective in this 2020 study was to revisit walnut tree sap flow and to determine whether vacuum applied to sap collection lines would substantially increase the production of walnut sap. Along the way, we made some somewhat startling and troublesome observations and formulated a next generation of questions that need to be answered to allow a viable walnut syrup industry to develop.
During the 2019 sap season, Future Generations University, with funding from the West Virginia Department of Agriculture, began a series of tapping studies on tree species other than maple. We tapped and made syrup from black walnut trees. We had trouble developing the expected natural vacuum on the 3/16-inch lines, even though they had plenty of slope. We assumed that the problem was related to vacuum leaks associated with a poor seal in the soft wood with the minimally tapered spouts.
