Original Gravity
Original Gravity (OG) is a basic measurement used in brewing that shows how much sugar is in the beer mixture before fermentation begins. Think of it like a recipe's starting point that helps brewers predict how strong the final beer will be. When you see this term on a resume, it usually means the person understands fundamental brewing measurements and quality control. It's similar to other brewing measurements like Final Gravity or ABV (Alcohol By Volume). Brewers use this measurement to ensure consistency in their recipes and maintain quality standards.
