This years Ofest used 50% Vienna, 30% Munich 6L, 4% Caramunich 2, and the balance pilsner malt. Just finished carbonating, I'm very happy with it. I too have ben toying with the idea of doing away with the Caramunich altogether in this beer. I agree that it's not really necessary and I the long boil (90 minutes) gets it to the color I want without it. The Ofest that I get on tap at Prost is the Hofbrau Ofest and is a light golden color, but still has a nice malty character. I prefer the slight orange tint of the traditional beer.
