The objective of this study was to investigate the effects of using acid on the chemical composition and the sensory quality of syrup produced after cleaning.
While there are both good and bad impacts on maple syrup producers due to climate change, overall, the effects will be negative. On the plus side, longer summers mean longer growing seasons for maple trees. However, regionally this longer growing season will increasingly be accompanied by periods of extended drought – particularly in more southern latitudes. This in turn may hinder root growth and performance. As maple syrup producers we are aware that anything which negatively effects maple tree roots is a concern because the roots are the origin for sap movement in the spring.
Because of the lack of knowledge on this topic and the frequent questions we received about the proper practice, we implemented a study in the summer of 2022 to examine the single and interactive effect of spout deployment date and open verses closed drops on sap yield.
Techniques used to produce maple syrup have considerably evolved over the last decades making them more efficient and economically profitable. However, these advances must respect composition and quality standards as well as authenticity of maple products. Recently, a new and improved high vacuum technology has been made available to producers to achieve higher sap yields. The aim of the present study was therefore to evaluate the effect of this new system on the yield of sap and on the sap and syrup chemical composition.
High levels of atmospheric sulfur (S) and nitrogen (N) deposition have substantially damaged ecosystems in the Adirondack Mountains of New York. Efforts to quantify damage have largely focused on aquatic effects2 However, limited recovery of surface water acid?base chemistry in response to large (>40%) decreases in S deposition over the past two to three decades has been attributed to depletion of soil calcium (Ca) and other base cations that may be ongoing despite declining acidic deposition. Availability of soil Ca has also been linked to changes in terrestrial faunal and vegetation communities in Adirondack hardwood forests.
Two ways to help satisfy the need for more high-quality sugar maple trees (Acer saccharum Marsh.) are by establishing plantations and by supplementing natural regeneration. To gain basic knowledge of seedling requirements for this species we studied the effects of soil moisture and nutrient levels on the growth of sugar maple seedlings in their first 3 years.
Between 2008 and 2011 we conducted a series of controlled experiments performed with commercial maple equipment to investigate the potential effects of the use of RO on the composition, properties, and flavor of the maple syrup produced.

Tapping depth strongly influences both sap yield and wounding. Numerous studies have focused on the amount of sap produced with ifferent depths, the most extensive work conducted by Morrow (1963), who found a tendency for increasing sap yields with increasing taphole depth. However, this work was conducted on gravity with 7/16” tapholes, so is less informative to most producers using 5/16” spouts and vacuum.
