Tapholes: Straight or Slanted?
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.
Taphole Staining and Sap Yields
The compartmentalization (walling off) process in maple trees and how it affects how to tap for maple syrup production.
Tapping Below the Lateral Line for High Maple Sap Yield
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.
Spout and Dropline Sanitation for High Maple Sap Yields
Techniques to manage spout and dropline sanitation in 5/16″ vacuum tubing systems for high yield maple production.
Identifying an Effective Defoamer for Certified Organic Maple Production
The combination of potential crop losses from foam-related incidents, reductions in crop value due to off-flavors, and ultimately the many adverse effects of such a large proportion of organic syrup with off-flavors potentially being sold to consumers, underscore the need to identify or develop a certified organic defoamer for maple production that is both more effective at controlling foam than the culinary oils that are currently used, and which results in no off-flavors when used in the quantities necessary to adequately control foam. Thus, the overall objective of this project was to identify a certified organic defoamer that met these criteria.

Researchers examine syrup darkening in uncoated and XL-coated jugs
Two studies were performed by the University of Vermont Proctor Maple Research Center in 2018 and 2019 to compare the rate of color (LT) change in maple syrup in uncoated and XL coated retail plastic containers.
