# Production of Beer This document describes the steps involved in the production of beer. ## Steps ### Stage 1: Mashing * **Crushing:** Crush the grain to facilitate sugar extraction. * **Mashing:** Mix the crushed grains with hot water to activate enzymes that convert starches to fermentable sugars. ### Stage 2: Filtration * Separate the wort from the solid grain residue (dregs) after mashing. * Allow only the liquid to pass through, which contains sugars and nutrients needed for fermentation. ### Stage 3: Boiling and Hops Addition * Boil the wort to stop enzymatic activity and extract aromas and bitterness from the hops added during this stage. ### Stage 4: Cooling * Quickly lower the wort temperature after boiling to prepare it for fermentation. * Important to prevent the growth of unwanted microorganisms. ### Stage 5: Fermentation * Add prepared yeast to the wort. * Yeast converts sugars into alcohol and carbon dioxide (CO2). * This is the stage where beer is born. * This stage takes approximately 14 days. ### Stage 6: Bottling * Filter the beer to remove any remaining solid particles (yeast and hop residue) and refine the flavor. * Transfer the filtered beer to bottles, adding sugar to allow for natural carbonation. * Seal and store for at least 14 days for proper maturation. ## Supporting Diagrams The document includes diagrams illustrating the following processes: * **Microbiology:** A diagram showing bacteria/microorganisms. * **Chemistry:** A diagram of a beaker containing a liquid. * **Filtration:** A diagram of a filtration system or process. * **Processes:** A diagram of a factory. The document is well-illustrated and provides a clear explanation of the beer production process.
