Another big run of 500 gallons. But this was not as sweet measuring only 2.2 degrees Brix. Typically we expect 2.5 degrees to 2.8 degrees Brix. Sap sweetness is measured on the Brix scale. Brix is a unit measuring the concentration (density) of solids in a sugar solution. 2.5 degrees Brix means that 2.5% of the weight is from sugar and the remaining 97.5% of the weight is from water. Water weights 8 lbs to the gallon. So in 10 gallons sap at 2.5% Brix only 1/4 pound of the total weight is sugar. The rest is water that will get boiled out. When more of the weight is from sugar it takes less boiling to get syrup.
