Concentrate is sap that is brought up to higher sugar levels which is generally around 10%. The concentrate is then brought to our high efficiency wood fired evaporator where the sap is boiled down systematically to 66.7 brix, the finished point of syrup. The evaporator consists of three main sections. The pre heater which brings the concentrate up to 180 degrees using steam from boiling concentrate further down the line. The next stage is the flue pan where the majority of the concentrates water is removed. Finally the concentrate goes into the syrup pan where it is given time to caramelize and reach the stage of finished syrup at 66.7 brix or 218 degrees.
