Er. Bikash Poudel

The paper presents the detail production process, activities involved for the production of quality beer, findings and analysis of those steps involved along with lab test of beer in one of the renowned brewery plant in Nepal. All those process and steps need to meet the specific criteria for the quality beer. The data are collected from direct observation, interviews with brew masters and detail study and observation of the processes involved in one of the top brewery plant in Nepal. Brewing, and pasteurization are the main steps involved in the production of brewery. Brewing  involves milling, mashing, lautering, boiling, cooling, fermentation and conditioning Cleaning-In-Process (CIP) and bottle washing involve before brewing. The work  resulted in finding of the following:

• The main cause of less production of beer bottles is frequent malfunctioning of leveling machine since it is not in good working condition. Whole bottling process is disturbed due to poor working of leveling machine.

• The percentage of caustic in bottle washing water is 2.77%  measuring at the end of bottling process.(at the end of the day) but the requirement if 3.3%.

• Effectiveness of the filler machine is 99.9%.

• The specific gravity of beer is 1.015
