Haven't tried the Chill yet, but saw several ads for it. Gonna give it a whirl this weekend.
My new favorite "summer beer" is from Leinenkugels over in Wisconsin. Their seasonal beers are always the best in the beer fridge, but I think they've outdone themselves with the Summer Shandy this year. A wheat beer with dashes of lemonade and honey... Can't have more than a couple without gut rot setting in, but I've never had a more refreshing beer when it's 85 and Minnesota humid. Check it out if you can! Their Sunset Wheat ain't too shabby either
