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.

Detecting and correcting vacuum leaks in maple tubing systems.
How to find and fix leaks at or near the taphole in 5/16″ vacuum maple tubing systems.
Looking around your woods youÕll see that there are far more trees on the landscape than you have time to measure. The science of forestry has taught us that similar stands (ones that have the same species composition, size classes, productivity, and management history) do not need to undergo a 100% census to get an accurate picture of what is there. Foresters use sampling methods that inventory stands to get an accurate representation of what is in them and the quality of the resource.
It is well recognized that microbial contamination of tubing systems can result in a substantial loss in sap yield if untreated. Over a decade of research and maple industry experience has produced a range of possible strategies to address sanitation-related issues in 5/16Ó tubing systems (Perkins et. al. 2019). Although rapidly adopted by many maple producers, due to the relatively short time period in which it has been in widespread use, there is far less understanding of sanitation in 3/16Ó tubing systems (Wilmot 2018). To address this knowledge deficit, we conducted a multi-year study at the UVM Proctor Maple Research Center to examine sanitation-related losses in 3/16Ó tubing systems to determine which approach(es) might best mitigate sap losses due to sanitation.

Analysis of the 2019 NASS survey of maple producing states.
This information was assembled to assist State and Provincial Maple Producer Associations in developing and offering a simple hydrometer accuracy-checking program for their members.
How may climate change impact the maple syrup industry? Our team of interdisciplinary researchers, ACERnet (Acer Climate and Socio-Ecological Research Network), has been working to understand the complex answers to this question for the past several years. In particular, we are interested in examining how climate impacts the timing of the maple tapping season as well as both the quality and quantity of sap collected during the tapping season.
Technological advances by maple equipment manufacturers, continued outreach and education by local, state, federal, and provincial maple organizations, and widespread adoption of new management practices by producers have revolutionized the maple industry over the last 20 years. The design and layout of sap collection systems and advances in vacuum pumps and releasers has resulted in higher per tap sap yields well beyond the old standards. Increased per tap volume has been matched with modern high brix reverse osmosis systems and efficiency gains in evaporators, pushing the economic potential of making maple syrup to new heights. Value-added products, niche marketing and branding, and social media and online platforms, coupled with health conscious and savvy consumers,have altered the retail sales landscape and linked rural maple producers to consumers around the world.
