The feasibility of re-tapping maple trees during the sap season was tested in 2019 and 2020 at Cornell University’s Uihlein Maple Research Forest in Lake Placid, NY. This report summarizes that project.
A study of the engineering and economic effects of heat exchangers in conventional maple syrup evaporators indicated that: (1) Efficiency was increased by 15 to 17 percent with heat exchangers; (2) Syrup produced in evaporators with heat exchangers was similar to syrup produced in conventiona lsystems in flavor and in chemical and physical composition; and (3) Heat exchangers reduce per unit production costs, and can yield greater production and higher profits.
Red Maple is a deciduous tree that can be 50 to 60 feet tall at maturity. It is wide ranging, and native throughout the eastern half of the United States. Red maple can be used for syrup production. However, it tends to bud and flower very early in the season, which has a negative effect on the sap, making the syrup season for the red maple very short.
Sugar maple is a deciduous tree that can grow to a height of 50 to 130 feet. It is native to the US, and found throughout the eastern states. Sugar maple is the primary source for maple sugar and syrup. Trees are tapped for syrup in late winter/early spring throughout New England. Sugar maple is also a valuable hardwood for a variety of products from flooring to cabinets.
In recent years, some maple equipment manufacturers have sold air injection (AI) technology equipment for the production of maple syrup. For purposes of the recent industry review conducted by the International Maple Syrup Institute, air injection technology is defined as the forced introduction of air through a series of perforated pipes submerged in boiling sap in the front and/or back pan of a maple syrup evaporator.
Maple syrup production contributes approximately $5 million annually to OhioÕs economy and provides supplemental nontimber forest product income for forestland owners. To better understand the factors that influence this important nontimber forest industry in Ohio, including producer heritage, producer age, sap collection methods, size of maple operation, and educational programming, we conducted a detailed survey of all known Ohio maple syrup producers (761 total producers). Over 80% of producers responded to the survey (620 respondents), making our analysis one of the most extensive of a maple industry in North America.
Due to projected increases in winter air temperatures in the northeastern USA over the next 100 years, the snowpack is expected to decrease in depth and duration, thereby increasing soil exposure to freezing air temperatures. To evaluate the potential physiological responses of sugar maple (Acer saccharum Marsh.) to a reduced snowpack, we measured root injury, foliar cation and carbohydrate concentrations, woody shoot carbohydrate levels, and terminal woody shoot lengths of trees in a snow manipulation experiment in New Hampshire, USA. Snow was removed from treatment plots for the first 6 weeks of winter for two consecutive years, resulting in lower soil temperatures to a depth of 50 cm for both winters compared to reference plots with an undisturbed snowpack.

Vacuum and gravity “pull” sap down lateral lines. Friction “uses up” energy. The energy that is lost in this case is vacuum (gravity is constant). Reducing friction in the tubing system preserves energy and preserves vacuum further up the line. If making tubing larger or smoother due to cost or implementation issues, the next best way to reduce friction in tubing is to reduce turbulence, especially at fittings. This can be readily achieved through two simple modifications. The first method is to incorporate a bevel into the entrance and exit of all fittings. The second modification is to incorporate an arc where sap streams meet.
