How long do kegs of non-pasteurized beer typically last when stored in a fridge?

Non-pasteurized beer, when stored correctly in a refrigerator, typically has a shelf life of about 45 to 60 days. This timeframe is primarily due to the presence of yeast and other microorganisms that can continue to ferment or spoil the beer, even at cooler temperatures.

Refrigeration helps slow down these processes significantly, but without pasteurization, the beer remains at risk of changing flavor or quality over time. While the exact duration can be influenced by factors such as beer style, production methods, and storage conditions, 45 to 60 days is widely accepted as a comfortable and safe range for enjoying the intended taste of non-pasteurized beer.

It's essential to understand that non-pasteurized varieties are more sensitive to temperature fluctuations and exposure to light, which can further impact their longevity and quality. By storing them in a fridge and adhering to this timeframe, one can enjoy a fresher and more enjoyable beer experience.
