Home Wine Making – How To Read A Hydrometer

Being a beginner wine maker, you will often come across wine making instructions or guides that calls for the use of a hydrometer. This piece of equipment will most probably confuse you as there is a high chance that you have never been aware of such equipment before – not to talk about knowing how to use it! Aquamax

For starters, let us first explore the purpose. Why do you desire a hydrometer in wine beverages making? The hydrometer allows your wine maker to check the alcohol level in the wine. This measures the specific the law of gravity of any liquid and by subtracting this reading before and after fermentation, wine beverages makers will be able to estimate the alcoholic beverages level of the wine beverages they are really making. 

Before we proceed on to reading the hydrometer, there is another important concept to see – the specific gravity. Specific gravity is the ratio of the density of a compound to that particular of water. Hence, the particular gravity of normal water will be equal to 1. 00 and specific gravity of juice used in wine making can be higher than 1. 00 (around 1. 07 to 1. 09). The reason for the higher specific gravity is because fruits juice contains sugar and other substance included in it which makes it much denser than pure drinking water. The precise gravity of liquor is 0. 787 which means it’s less heavy than water.

With the above concept at cardiovascular system, it becomes clear how wine makers estimate the alcohol level. During fermentation, sugar (heavier than water) in the fruit drink is changed into liquor (lighter than water). Therefore, the specific gravity of fruit juice will fall season during fermentation, and once this value stop reducing, you know that fermentation has ended and all the sugar has recently been converted into alcohol.

Permit us now explore how one can15484 use and read a hydrometer. First, you will need to pour some of the fruit drink into the hydrometer and ensure that the light is floating and not touching the base. Examine off the scale. The reading should be around 1. 07 to you. 09. In addition, the hydrometer should also come with an unique temperature static correction chart and therefore, you will also need to measure the temperature of the liquid and apply the correction value to the reading.

After 2-3 several weeks of fermentation, take another reading by repeating the same procedure. If fermentation proceeded smoothly, the specific gravity should be below 1. 00. If not, you will need to provide your wine more time to carry on fermenting.
