How to Use a Maple Hydrometer
To make homemade maple syrup properly, you need to learn how to use a hydrometer. This tool measures the density of liquids. In the case of maple syrup production, density is key to creating a rich maple flavor. By measuring the density of your syrup, you can determine what percentage of the liquid is sugar. The Brix scale measures this. Maple syrup should be between 66.50 and 67.50 degrees Brix for ideal viscosity and maple flavor. Does this Spark an idea?

1
Fill the hydrometer cup with a sample of maple syrup while the syrup is still hot. Pour enough syrup to get as close to the top of the cup as you can.
-
2
Lower the thermometer into the cup. Allow the maple syrup to cool down to 68 degrees Fahrenheit.

3
Lower the hydrometer into the cup very slowly as soon as the thermometer hits 68 degrees Fahrenheit. Never drop the hydrometer into the cup. If the syrup is too thin, the hydrometer can hit the bottom of the cup and crack. When the hydrometer stops sinking and starts to float, take the density, or Brix value, of the syrup by reading the markings on the side of the hydrometer. The optimum levels for maple flavor are between 66.50 and 67.50.

Make adjustments to the syrup if the sample does not fall between the optimum Brix values. If it is lower than 66.00, you need to boil it more. If it is higher than 67.50, you can add small amounts of maple sap to thin it out.

Tips & Warnings
Always clean and dry the hydrometer, hydrometer cup and thermometer between measurements.
The minimum Brix value for maple syrup in most of the United States is 66.00. Some states, including Vermont and New Hampshire, set higher values. Vermont and New Hampshire set a minimum Brix value of 66.90 for maple syrup offered for sale.
