Still scratching my head on this. First half of the season every sap measurement was around 4% sugar, then toward the end it tapered down to around 2.5% Normally my trees start around 2.5% and end up around 1.5%. In the end my average sap-to-syrup ratio was 31.4 to 1. Hands down best ratio I've ever seen. Sap amount was about average, so all in all translated to an above average year.
