Why use a hydrometer?
Many brewers don’t use a hydrometer and have never had exploding bottles. One day their luck will run out! Brewers Yeast is a living organism and, as such, may perform differently from brew to brew. We recommend the use of a hydrometer for checking that fermentation is complete before bottling. The hydrometer is a simple device which, when floated in a sample, gives an indication of the density of the brew. Two separate samples over 24hrs with the same reading indicates that fermentation is complete (Final Gravity – FG). Once FG is achieved, have a taste and smell of the brew (an infection is usually a sour taste). If it tastes and smells like beer you can bottle confidently in the knowledge that the correct amount of priming will produce the right amount of fizz with no explosions!
