Final answer:
Pasteurized draft beer is good for about 45 to 60 days in the refrigerator. Louis Pasteur's discovery of the pasteurization process helped prevent the spoilage of beverages like beer. Effective temperature control is essential to prevent bacterial growth and maintain beer quality.
Step-by-step explanation:
Pasteurized refrigerated draft beer typically remains good for about 45 to 60 days before its quality starts to deteriorate. The pasteurization process that Louis Pasteur discovered in 1856 helped in preventing microbial fermentation that spoils beer and wine. Pasteurization is crucial in ensuring the longevity and safety of various beverages and dairy products by eliminating pathogens.
While the shelf life of milk can be extended through methods like high-temperature short-time (HTST) or ultra-high-temperature (UHT) pasteurization, beer does not benefit from such long-term stability due to its different composition and packaging. It is important to store pasteurized beer at consistent, cold temperatures to maintain its quality and prevent the growth of bacteria. Temperature control is key; perishable items kept between 4 and 60 degrees C (40 and 140 degrees F) for more than two hours can become unsafe due to bacterial growth.
It is also essential to consume the beer before prolonged exposure to air, which can lead to oxidation and a vinegary taste. Similar to practices in food safety, such as regular handwashing and using fresh ingredients, proper storage and timely consumption of beer are vital for maintaining its quality and safety.
