Someone mentioned to me a while back that they thought Skyy was manufactured in San Jose. I finally made it over to their Wiki page, and it looks like this is true! Production and bottling for Skyy Vodka is handled by Frank-Lin Distillers in San Jose. Ethanol is delivered using the railroad system, then the ethanol is mixed with filtered and deionized water and flavoring is added (for certain Vodkas).
Now you know that when you order a martini or mixed drink, if you pick Skyy vodka you are benefiting a San Jose company and the local economy. Speaking of which, I have a whole Google Doc filled with local companies that can help you prioritize your holiday shopping selections. You can access it right over here.
