How Much Does a Gallon of Maple Syrup Weigh?
Start with the USDA gallon baseline, then adjust for Brix, grade, temperature, and packaging loss.
The calculator uses a 66 Brix baseline from USDA weights-and-measures data and applies small corrections for syrup strength, temperature, and handling loss.

Maple syrup have a different weight then water because maple syrup contains more sugar than water. A gallon of water weigh approximately 8.34 pounds. However, a gallon of maple syrup weigh more then a gallon of water.
Specifically, maple syrup contain sugar dissolve in water. Most maple syrup contains 60-69% sugar solid by weight. Therefore, a gallon of maple syrup weigh approximately 18% more then water, it is roughly one-third heavier then water.
How Much Does Maple Syrup Weigh and Why It Changes
The weight of maple syrup also depends upon the Brix levels of the syrup. Brix is a measurement of how much sugar are contained in maple syrup, as demonstrated with a refractometer. A Brix level of 66 mean the syrup weigh 11 pounds per gallon of maple syrup.
Additionally, a Brix level of 67 or 68 will indicate that the maple syrup weigh more per gallon. The more higher the Brix level, the more sugar and the less water is contained in the syrup. Therefore, the higher the Brix level, the more higher the weight of the maple syrup.
The weight of maple syrup can also change with the temperature of the syrup. Hot maple syrup will weigh less per gallon of syrup then cold maple syrup. Maple syrup producer typicaly chill syrup to 68 degrees, the standard room temperature, to ensure the weight of the syrup remain steady during production.
Additionally, the grade of maple syrup and the way it is boiled can also impact the weight of maple syrup. Grades of maple syrup like golden, amber, dark, and very dark result from different boiling process and different maple sap source. The grades may have slight difference in the Brix level of the syrup.
The Brix level determine the weight of the syrup. Furthermore, during the production of maple syrup, there may be a loss of syrup during the transfer from the evaporator to the bottles and jar of syrup. This loss of syrup is call “transfer loss.” Therefore, a batch of maple syrup may not weigh the same as the amount of gallon of syrup that are pour into the bottles and container to be sold.
When maple syrup is produce in large batch, it is important to account for the transfer loss. There are many task that must be performed in a maple syrup operation that depend upon the weight of maple syrup. The bulk hauler that transport maple syrup to various market must calculate the cost of shipping the maple syrup based off the weight of the maple syrup being shipped.
Therefore, knowing the weight of the maple syrup is needed to calculate the shipping cost of the maple syrup. Additionally, the producer of the maple syrup must know its weight, as well. If the weight of the maple syrup is too heavy, the truck may exceed the axle limit for the maple syrup truck.
The retail market must know the weight of maple syrup to determine how many product can be placed on the shelf in the retail store, as well as to calculate the shipping cost of the maple syrup to those retail store. Finally, home cook can use the weight of maple syrup to determine how many cup of syrup will be needed for a given recipe. One cup of maple syrup weigh 0.7 pounds.
A tool can be create that allow producers of maple syrup to input the volume, the Brix level, and the temperature of the maple syrup. The tool will calculate the gross batch weight of the maple syrup, the amount of sugar solid in that batch, and the net amount of syrup that will fill the bottles of maple syrup. The amount of sugar solid in the maple syrup is important; at 66 Brix, two-thirds of the maple syrup is pure maple sugar.
The maple sugar is the main value of maple syrup. The water content in maple syrup may fluctuate due to the temperature of the syrup. Therefore, measuring and tracking the amount of sugar solid and the weight of the maple syrup allow for the best decision to be made regarding the maple syrup product.
