Can I find more information about how long their liquor is good for at the websites of various companies?

We checked several websites of major liquor companies (Skyy, Bacardi, Jose Cuervo, et al) and found that not only do they not have such information posted there, they generally don't even have a customer service line posted there, just a customer service email option. Bacardi lists an 800 number (1-800-Bacardi) on their bottles, but many others do not. "Product of Mexico" is about as specific as the Cuervo bottles get, for example.
 
However, for the curious, we do recommend checking out some of these websites, as most of them are state-of-the-art cool. Check out Skyy.com, for example. (Note that we are not endorsing Skyy or any other brand here, but we'd be lying if we didn't admit to just a touch of website envy.)
