That is an interesting project. Ray Daniels' Designing Great Beers is built from the same type of source material. But it is now out of date. A project like this could lead to a new edition.
The winners of all SNERHCs since 2003 may be found at http://www.undergroundbrewers.org/snerhc-info/ The winners of SNERHC 2022 will be posted there as well, right after BOS judging is complete in late February. I believe that all competitions post their winners publicly but I could be wrong.
We do not collect recipe info from our entrants. This is intentional. A recipe is private information unless the brewer chooses to disclose it. It tends to be unhelpful to judges; they should be judging the beer against the declared style rather than the intended one. And it tends to be unhelpful to other brewers; they will be brewing on a different system, using different procedures and different water, yielding a different result.
Everyone is free to contact the listed winners and request recipes, of course. And the winners may indulge, for whatever that is worth. But in the 30+ years that the Underground Brewers have been hosting SNERHC, and especially in the 14 years that I've been the organizer, we've never felt is necessary to require that information as a condition of entry.
