Alcohol hydrometers and refractometers are essential bits of kit that enable you to accurately work out the gravity — or alcohol content — your finished beer, wine or cider has.
Doing so also enables you to understand how fermentation is going, and when it is coming close to completion.
At Get Er Brewed we have a great selection of affordable hydrometers and refractometers, and a collection of hi-tech digital refractometers too. Take a look at the detailed descriptions of each to learn which is best for your needs.
