The sugar and acid degrees are two factors of making a perfect batch of wine and so any adjustments to the process are the results of those tests. As you probably already know the sugar level of your wine is incredibly important as it is the sugar that the yeast feeds off of in order to produce the alcohol. The volume of sugar you use will determine the amount of alcohol that is present in the final batch but to do such tests you will need to have a wine making hydrometer.
The gravimeter lets you accurately tests and take measurement of the sugar that is in the juice and the amount of alcohol that will result from the sugar. As a result, you will also be able to measure how much additional sugar you may need to add into the juice.
A gravimeter is essentially a glass tube that contains a weight that will float in water. Sugar levels can be tested by reading how low or high it floats at in any hydrometer their scale provides a reading of how much alcohol it has. The scale can be read when the fermentation process begins to let you know if you need to add more sugar based on the amount of alcohol that you want to be present in the final wine.
If you think you need to change the sugar level to raise the alcohol level you’re probably curious what kind of sugar you should use. It helps to remember that different types of sugar will offer different characteristics. [Corn sugar and cane sugar are usually the cheapest] and the most available, though, there’s nothing to stop you from experimenting with other types of sugar, if you have that sugar around.
You’ll need to try and possible change the acid level. Keep in mind that having the right acid level will balance out your wine as well as assist in the fermentation process as it is important to keep in mind that the level of acid changes in different fruits.
The best way to test the acidity level of your juice is to use a titration kit which helps you to measure determine how the wine will actually taste. If too much acid is present in the wine in the wine then it will taste bitter or sour, however, if it doesn’t have a sufficient acid content, it’ll be flash. Based on those readings,it’ll be easy for you to tell whether or not you need to make changes to the acidity level of your wine. Should you discover that you do need to change anything you can accomplish it using one of three different fruit acids: citric, tartaric and malic fruit acids.
Some ways to change the flavor the wine during bottling involve combining it with other fruit based wines, tossing in some spices, flavor enhancements. You could also fortify your wine with something such as grain alcohol or the like. The most critical rule that should be followed while making final adjustments is to ensure that you adjust in small amounts, so basically, always play with small portions and not everything you have produced.
