Been drinking local beers here to INDY, but the best this summer has been Bee Creek Brewery's Hoosier Honey Wheat. Best American made Wheat beer I have ever tasted by far and in the same class with Weihenstephaner and Ayinger's World class Hefeweizen's IMHO.
Other incredible brews are the Three Floyds monthly releases over the spring and their Moloko Milk Stout. I gave it to a friend as a gift, and his favorite beer is stout's. He liked the Left hand Milk stout as a go to beer until he tried the Moloko. Now, it's his favorite bottled beer available in INDY.
The other Three Floyds offerings were Dreadnaught Double IPA, Rabbid Rabbit Saison, BlackHeart English IPA, and Apocalypse Cow Double IPA. Really solid with none less than an A-.
