Suds, a cold one, brew. However you name it, beer is a big thing now and these free beer label vector graphics will help you if you wanted to open your own microbrewery. If you have no need for the labels themselves but just wanted to have some editable beer images you can just take some of the vector beers and use them too!
Remember, the zip file comes with both a .jpeg image and a fully editable .eps image allowing you to customize the image exactly how you see fit. If you need a program to edit the .EPS, try Inkscape.
