1) At this point, you should measure the original gravity (OG) of the wort. To do so, use a sterilized ladle to add some of the liquid to a graduated cylinder. Insert a hydrometer into the liquid. Take note of the measurement: it should be around 1050.
2) At this point, you should measure the final gravity (FG) of the beer. To do so, use a sterilized ladle to add some of the liquid to a graduated cylinder. Insert a hydrometer into the liquid. Take note of the measurement: it should be around 1010. Discard this liquid sample.
Good to know: The alcohol content of this beer recipe is 5.3%. Here is the formula for calculating the alcohol content of beer: OG – FG ÷ 7.5 = %
