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