A brewing hydrometer is a very useful tool for any kind of fermentation. By tracking starting gravity and finishing gravity, you will be able to establish the level of alcohol that has been produced. This is also very helpful when trying to identify if fermentation is complete, which is very important to establish before bottling if you wish to avoid bottle-bombs.
This hydrometer is ideal for wine-making, beer-brewing and cider-making. It includes three scales, allowing you to read specific gravity, potential alcohol, and grams per litre of sugar.
