The “Jones Rule of 86” Revisited
The Jones “Rule of 86” was devised in 1946 by C.H. Jones, a scientist and educator at the University of Vermont. The gist of the rule is that ifone divides 86 by the sugar content of sap, you can estimate the amount of sap required to produce a gallon of syrup.
The 3/16 phenomenon
Using smaller-diameter tubing can create a natural vacuum which can increase sap production. This article details some research into this method of sap collection, and offers tips on some practical applications.
The aesthetics of sap collecting
A guide to keeping up appearances in your sugaring operation.
The Chemical Composition of Maple Syrup
This article is meant to be an introduction to the chemistry of maple sap and syrup: in particular, what makes this sweet liquid maple syrup instead of just a concentrated sugar solution? The types of sugars, the trace ingredients, and the mineral content make maple syrup more than just plain sugar water.
The complex relationship between climate and sugar maple health: Climate change implications in Vermont for a key northern hardwood species
This study compared 141 ecologically relevant climate metrics to field assessments of sugar maple (Acer saccharum Marsh.) canopy condition across Vermont, USA from 1988 to 2012. After removing the influence of disturbance events during this time period to isolate the impact of climate, we identified five climate metrics that were significantly related to sugar maple crown condition. While three of these are monthly summary metrics commonly used in climate analyses (minimum April, August and October temperatures), two are novel metrics designed to capture extreme climate events (periods of unusual warmth in January and August). The proportion of climate-driven variability in canopy condition is comparable to the proportion accounted for by defoliating pests and other disturbance events.
The Cost of Maple Sugaring in Vermont
Our objectives were to develop time series of maple production costs and to observe the effects of changing technology, fuel price, interest rate, and sap sugar content on production cost. In addition, the relationships between major production cost items were examined.
The Cost of Production for Vermont Maple Syrup
The University of Vermont Maple Benchmark project is advancing the study of maple economics and supporting management decision making at the individual business level. The following article summarizes the cost of production findings from 2014 and synthesizes key trends in business management.
The Economic Contribution of the Vermont Maple Industry
Maple and the maple industry are synonymous with Vermont with its sugar houses and mountain sides with colorful leaves in the fall. The maple industry, beyond producing maple products, contribute to the image of Vermont and to its tourism. This report focuses on the economic contribution of the maple production supply chain from equipment manufacturing, equipment sales, installation to sugaring, packing and production of maple products. Though putting a dollar amount on the contribution of the maple industry to tourism in Vermont would be a complex task, and beyond the scope of this report, the contribution is likely very significant.
The Economics of Maple Syrup Production in Ontario
There is ample room to grow the maple market in Ontario. OMSPA commissioned this report and the accompanying budgeting tool to assist maple entrepreneurs in building a solid BUSINESS PLAN to tap into this incredible business opportunity. The accompanying Excel budgeting tool facilitates the exploration of various scenarios of yield, scale, and capital investment to measure the impact on the bottom line profitability.
