Product Spotlight: Triple Scale Hydrometer
A Triple Scale Hydrometer is a winemaking instrument used to measure the progress of fermentation and determine the alcohol percentage it will yield.
How does it work?
The Triple Scale Hydrometer measures the density of a liquid in relation to water. In winemaking, you are measuring how much sugar is in the wine. The more sugar that is in the wine, the high the hydrometer will float. As fermentation proceeds and sugar turns in to alcohol, the hydrometer will slowly sink. When fermentation is complete the hydrometer will stop sinking.
How do I read it?
Triple Scale Hydrometers have their name because they indeed have 3 scales. The 3 scales are Specific Gravity, Brix, and Potential Alcohol.
Specific Gravity – is the ratio of the density of a liquid to the density of water. In winemaking, as you add sugar, the specific gravity increases. It indicates the amount of fermentable sugar or potential alcohol in the wine.
Brix – the measurement of the sugar content in grapes, must, and wine. This indicates the ripeness of the grapes at harvest. To get an alcohol conversion, multiple your Brix by .55.
Potential Alcohol – the total measurement of the alcohol that wine may contain, once fermentation is complete. This includes the levels of glucose and fructose. The levels of each will enable the winemaker to determine the conversion rate of sugar into alcohol.
How do I use it?
Place a sample of your wine into a test tube. You can use a wine thief to retrieve the wine from your vessel easily. Place the hydrometer into the test tube filled with wine. It will take a moment for it to stop spinning and moving around. Once it becomes still, record the data from each scale. It is a good idea to do this when you receive your must or juice so that you have your starting numbers. It is always a great idea to track your process for any future possible issues, or if your wine comes out amazing and you’d like to repeat the steps again for your next batch of wine.
