What is the significance of 'Original Gravity' (OG) measurement in beer brewing?

The significance of the 'Original Gravity' (OG) measurement in beer brewing lies in its ability to indicate the amount of fermentable sugars present in the wort before fermentation. Original Gravity is a measure of the density of the wort relative to the density of pure water, typically expressed as a specific gravity reading (e.g., 1.050). It essentially tells the brewer how much sugar is dissolved in the wort. This measurement is crucial for several reasons. First, it allows brewers to estimate ....
