There is a lot of shady practices in both the maple syrup industry and in the honey industry. I predominantly use maple syrup in my household. Honey, second and agave, a very very low third. Typically we go through about 5 litres of maple syrup a year, so we place our orders now, and keep it in our cold cellars. You just have to take your best guess and hope that you don't run dry through the year. LOL
