Application Importance of Brix in Brewing

An important measurement in beer is known as gravity. This term refers to the total amount of dissolved solids, mainly sugars, in solution. These sugars are measured in Brix. Specific gravity is the ratio of how a liquid’s density compares to that of pure water at a specific temperature. This value is measured throughout the brewing process due to its dynamic nature. Measuring specific gravity helps monitor the fermentation. Taken at different intervals, it allows you to:

  1. Ensure there is enough sugar present to achieve the desired alcohol level
  2. Determine when fermentation is complete
  3. Estimate the Alcohol By Volume (ABV) of your finished product

When thinking about specific gravity in beer, there are two things to consider. The first is that dissolved sugars and other total soluble solids (TSS), as seen in wort, increase the density of liquid. The second is alcohol content. Yeast consume the sugars and convert it into alcohol, which is less dense than water, decreasing the specific gravity decreases.

It is important to note that once fermentation begins, ethanol will interfere with sugar readings and you will not be able to take a direct reading of either the alcohol content or the sugar content. However, with the right table, you can still use a refractometer to measure post-fermentation Brix levels and correct for the interference to accurately determine alcohol content.

Meters

Digital Refractometers

Digital Refractometers offer a simple way to measure the sugar content in wort. One degree Brix is equal to 1 gram of sucrose in 100 grams of water. Calibration is simple using only a drop of deionized water. Then a small amount of wort is placed on a sealed prism and a temperature compensated measurement is then provided. A quick conversion from Brix to gravity and you are done!

  • Sample sizes as small as 100 μl
  • Fast automatic temperature compensation measurements
  • High accuracy (± 0.2%)
  • Easier to read LCD
  • Small size and portability

Note: These meters only measure sugar content. The amount of sugar present indicates the potential amount of alcohol that can be fermented.
