A general rule of thumb is that beers from large breweries will have a shelf life of approximately 8 to 12 months if refrigerated properly and kept from direct light, or 4 to 6 months at room temperature.
In normal conditions, pure water filled in a bottle lasts for 4-8 hours. If it is refrigerated, it can last up to 4-5 days. Once you open the sealed bottled water, it lasts not more than 4-8 hours. That depends on upon what condition and environment you are into.
