Brewers are responsible for the entire brewing process, from sourcing ingredients to packaging and distributing the finished product. They oversee every step of production, ensuring that the beer meets the desired quality standards. Key job responsibilities include:

1. Recipe Development and Quality Control

Brewers develop and refine recipes for new beers, ensuring that they meet the desired flavor profile. They also conduct quality control tests throughout the brewing process to ensure that the beer meets the desired specifications.

• Develop new beer recipes and refine existing ones.
• Conduct quality control tests on raw materials, in-process products, and finished products.
• Troubleshoot production problems and implement corrective actions.

2. Brewing Process Management

Brewers manage the brewing process from start to finish, ensuring that the beer is produced efficiently and to the desired quality standards. They oversee all aspects of the brewing process, including:

• Mashing: Converting the starches in the grain into sugars
• Lautering: Separating the wort (sugar water) from the grain
• Boiling: Adding hops to the wort to add flavor and bitterness
• Fermentation: Converting the wort into beer by adding yeast
• Conditioning: Allowing the beer to mature and develop its flavor

3. Equipment Maintenance and Sanitation

Brewers are responsible for maintaining and cleaning all of the equipment used in the brewing process. This includes cleaning and sanitizing tanks, kettles, pumps, and other equipment. They also perform regular maintenance on equipment to ensure that it is operating properly.

• Clean and sanitize brewing equipment.
• Perform regular maintenance on brewing equipment.
