Total Yields From Red Maples

Many producers include red maples as crop trees without a second thought. And still many others will walk past red maples with a roll of tubing. Why the difference? Much of it arises from some lingering perceptions about red maples – that they produce lower yields or stop running earlier than sugar maples, or produce syrup with inferior flavor or that exhibits buddy flavor earlier than sugar maple.

Maximizing production through sustainable tapping

Optimal syrup production starts at the tree, and requires thinking beyond the current season. This session focuses on tapping practices that both maximize yield and ensure long-term sustainability of your sugarbush. Topics include timing of tapping, taphole placement, taphole sanitation, and sap collection.

Identifying Maples for Maple Syrup Making

This is a basic guide to identifying three maple species during the growing and dormant seasons. We look at key identifying characteristics such as branching patterns, leaf shapes and bark patterns. Additionally, we include identifying characteristics of two other trees that could cause confusion in the sugar bush.

Quality control guide cards

These handy cards provide checklists for color, clarity, density, and flavor, with notes on why syrup may not measure up to standards.

Maple syrup production from sap preconcentrated to ultra high °Brix by membrane technology: Composition and properties

Maple syrup is produced typically from maple sap concentrated by nanofiltration or reverse osmosis at a moderate °Brix level ranging from 6 to 16 °Brix followed by heat evaporation. Recently, new membrane processes have been developed to concentrate maple sap to ultra-high °Brix reaching up to 40 °Brix. The aim of this study is to evaluate the effect of this ultra-high concentration of sap on the composition, the properties and the cost of corresponding maple syrup. Results showed some differences in chemical composition and properties between syrups produced from low and ultra-high concentration of sap. Syrups produced from ultra-high °Brix concentrated sap had lower concentrations of potassium and polyphenols, a lighter color and distinctive flavor. This was mainly observed when no modification were applied to the heating pattern in the evaporator pans. However, syrups produced by modulation of the heating pattern in the evaporator had color, flavor and taste similar to control syrups. These results demonstrate that syrups with comparable sensory properties can be obtained from low and ultra-high concentrated sap by adjusting the heating time depending on the initial °Brix. The concentration process to ultra high °Brix allows for a concomitant reduction of the production costs and a modulation of syrup quality.

Sweet Talk: All Things Maple

The Cornell Maple Program presents Sweet Talk, with hosts, co-directors of CMP, Aaron Wightman and Adam Wild. Your hosts will present the latest research, news, and trends in the maple industry, with various guests including other maple researchers, industry experts, and local sugarmakers.

Sugar Maple Health & Climate Change 

There has been a lot of research over the years investigating the health and productivity of sugar maple in Vermont and the broader region. What do these findings tell us about how sugar maple might fair under a changing climate? Are there strategies that can be used to bolster the resilience of sugar maple?

Are Sweet Trees Actually Sweet? 

The Cornell Maple Program in Lake Placid, NY has been managing groves of sugar maples selected and propagated for having genetically sweeter sap for close to 40 years. Are these trees actually sweeter and how much sap do they produce? Recent sampling looked back over the plantation to test the heritability of sap sweetness.
