I think you should not enter. It could mess with the judging dynamics of a flight. For instance, if your beer was early in the flight and amazing (or terrible) it could influence the judging of the rest of the flight, and since you are ineligible, that would be unfair to the other entrants.

What you could do is send a bottle or two to the site director and have him give it to the judges as a DQ'd entry for them to fill sheets on after the flight was completely judged and ranked. After they fill sheets you can reveal to them it was yours...or not, whatever.

I would encourage you to skip the decoction on the roggenbier though. It's a tough enough beer to get right anyway, so why make it even harder by adding unnecessary complexity. Let the beer itself be the challenge, not the brew day.

8 ingredients. Illegal.

Ah, seven different ingredients...i was just giving you grief Olan

I have tasted a few roggenbiers. NHC final round, high scoring roggenbiers, actually.

I haven't brewed one though.

I would say success in the style is to get a lot of rye flavor, lots of European style caramel/bready flavor, and enough hefe yeast character to notice it. And it should be quite drinkable. I can only imagine that it is a very hard style to pull off with all of those parameters. Quite a complex beer.
