But when the weather starts to warm early in the spring and temperatures seem favorable for good sap flows, they are sometimes left wondering why the sap hasn’t started to run. There are several explanations for the disconnect between warm air temperature and a lack of flow during
the early season.

All Things Evaporators

Many producers refer to boiling as the art of making maple syrup. Boiling on a modern evaporator is a process requiring about 45 minutes to move from the inlet at the start to the draw-off at the finish. Bringing 2% sap through a float at the back of the machine and moving the sap forward through a series of channels until it reaches 66 Brix at the opposite end may sound quite simple; however, properly boiling syrup is a very complex scientific process based on physics, chemistry and microbiology.
