If you are reading this and not sure what I’m going on about – try reading this article on how to use a hydrometer.

Brewers friend – Wide range of calculators for all things home brew. More catered towards wine making and beer – the estimated percentage of alcohol calculator is useful – or you can use the table below to get a quick idea.
