Finally, the higher the density at which syrup is finished, the less that can be made from a given amount of sap. For example, a producer making 66 gallons of syrup finished at 67 degrees Brix could make 67 gallons of syrup finished at 66 degrees Brix from the same amount of sap. Refractometer Use Using a refractometer to determine the density of syrup by measuring its refractive index is an accurate, yet simple method. Refractometers are precise instruments and are particularly well suited for determining the density of syrup in Brix units at room temperatures. They are also commonly used to determine the density of syrups entered in various competitions.

Only one drop of syrup is required for this measurement. Hydrometer Use Hydrometers are the instruments of choice for most maple producers in determining and checking syrup density. They are well adapted for use in the sugarhouse and can provide accurate density determinations. All that is required to determine syrup density is a calibrated hydrometer, a hydrometer cup and a thermometer. The hydrometer is carefully placed in the syrup in the hydrometer cup.
