Technical Position Paper on Air Injection

The use of air injection technology in the maple industry can be defined as: the forced introduction of air through a series of perforated pipes submerged in the boiling sap in the front and /or back pan of a maple syrup evaporator. Several studies conducted in recent years have investigated aspects of the use of air injection technology in the process of maple syrup production.

Results from the 2009 New England tapping survey

Results of an annual survey conducted of New England sugarmakers, capturing information on production practices and results, such as types of equipment used, sap sugar content, sanitation practices, and other data.

Invaders in the sugarbush

Invasive exotic plants are becoming more prevalent and can have a negative impact on sugarbushes. Maple producers need to know how to identify and eradicate invasives.

Tapping red maple

Sugarmakers should consider tapping red maples to supplement sap production from sugar maples.

Cold-season patterns of reserve and soluble carbohydrates in sugar maple and ice-damaged trees of two age classes following drought

This study examines the effects of summer drought on the composition and profiles of cold-season reserve and soluble carbohydrates in sugar maple (Acer saccharum Marsh.) trees (50-100 years old or-200 years old) in which the crowns were nondamaged or damaged by the 1998 ice storm. The overall cold season reserve carbohydrate profiles in twig wood tissue of drought-stressed (DS) trees and non-drought-stressed (NDS) trees were generally similar, although differences were observed in the amount of reserve carbohydrates in DS and NDS trees. The cold-season level of starch stored in DS trees in early autumn in the wood tissue was about one-third to one-fifth that in NDS trees. The cold season sugar content in the DS trees was significantly greater than can be attributed to degradation of stored starch, only.

Maples under pressure

How sap pressure and flow interacts in maple trees during the sugaring season.

Metabolism Off-Flavor In Maple Syrup – Part I: Identification of the compound responsible for metabolism off-flavor

Research on metabolism off-flavor in maple syrup at the University of Vermont Proctor Maple Research and Extension Center (PMREC) had two main objectives. The first was to identify the primary compound(s) responsible for metabolism off-flavor in maple syrup. Once the responsible compound or compounds were identified, measures to reduce or remove the off-flavor from finished maple syrup could be investigated. Thus, the second main objective was to determine whether a technique could be found that maple producers and packers might employ to effectively remediate the flavor, and thereby increase the economic value, of metabolized maple syrup.

What does a taphole do to a tree?

Tapping trees creates a wound that the trees are usually able to heal. But what is the impact of tapping on trees?

Achieving the Right Syrup Density

Achieving a consistent and acceptable density level for maple syrup continues to be a challenge for many producers.

Sugarmakers as teachers

One way that maple producers can gain useful information is by attending the education programs put on by Extension in conjuction with county and state maple organizations, where speakers include not just university and government specialists, but also sugarmakers who share their knowledge and experience.
