One of the more specialized pieces of beer equipment, beer refractometers allow you to measure the amount of sugars in your home brew. Sugars are measured in brix. Once you know the amount of sugar in your batch of home brew, you can gauge how far along the fermentation process your beer has come and ultimately determine when fermentation ends. This can ensure that you bottle your beer at the right time. E.C. Kraus offers high quality beer refractometers and other pieces of home beer brewing equipment for home brewers.
