Yes, to be fair, I'm lazy and use flaked maize! At some point maybe I'll have enough ambition to use grits and a cereal mash for authenticity. But as Ed said, it's a nice pint, with maize or otherwise.
Cluster hops were traditional but IMO, it's not a great hop. That's why I finish with Styrians now. Not really authentic but hey, that's why we brew right?
