This is a unit of concentration, so the unit is always expressed in reference to 1 gallon ('per gallon'). To understand this, let's look at the unit of points/pound/gallon. gravity) changes depending on the volume. It is important to realize that the total amount of sugar is constant, but the concentration (i.e. When all-grain homebrewers get together to brag about their brewing prowess or equipment and they say something like, 'I got 30 (ppg) from my mash schedule', they are referring to the overall yield from their mash in terms of the amount of wort they collected. The Extract Efficiency section and table gave us the typical malt yields that allows us to evaluate our mashing process. 5 gallons.Д«ut, when it comes to the efficiency of the mash and lauter, we want to think in terms of the pre-boil gravity. When brewers plan recipes, they think in terms of the pitching OG, which assumes that the wort volume is the final size of the batch, e.g. And, ninety percent of the time, the pitching OG is what people are referring to because it determines the strength of the beer. There are two different original gravities (OG) that matter to a brewer: one is the pre-boil or extraction OG, and the other is the post-boil or pitching OG.
