Miller Light is my favorite light beer.
It is not overall my favorite though. My two Favs come from two smaller Wisconsin Breweries.
The first is Spotted Cow by the New Glarus Brewery http://www.newglarusbrewing.com/. It is a smooth and refreshing beer that is just right.
The 2nd would have to be Leinenkugel's Summer Shandy, its a great summertime beer with just a hint of lemon on those summer days its really refreshing..
So have at it! What are your favorite brews?
