Syrup season usually starts in March when ideal temperatures occur. In order for sap to flow the temperature should be around -5C at night and +5C throughout the daytime. The syrup season will usually last an average of about 3 weeks each year. After this the buds come out and the sap collection is complete for the season. It takes 40L of sap to make 1L of Maple Syrup.
Since 2010, the IMSI (International Maple Syrup Institute) has reviewed and consolidated information related to the nutritional and health benefits of pure maple syrup. The IMSI will continue to monitor related scientific findings related to the nutritional and health values of pure maple syrup.
