This photograph of a painted brew kettle next to a rack of beer kegs shows the true workings of a brewery. Although, much of the work is technical such as determining ingredients, times, and temperatures, it also involves elbow grease. A full size keg can weigh over 160 pounds, and empty weigh nearly 30 pounds. The paint is most worn on this kettle right below the lid. Even with forklifts and other materials movement equipment, there are still tubes to connect, valves to adjust, and ladders to climb.
