Beer recipes are a dime a dozen. Recipes in general can't be copyrighted, the legal folks can correct if wrong (looks like they already have weighed in). As said keep it secret, like the Coke Cola recipe if you think it is supper special.
There are recipes for Pliny the Elder on the web, supplied by Vinnie Cilurzo. Now why would he do that? He says the equipment and procedures are hard to duplicate, so you get a similar beer, but not exactly the same. Sort of like Grandma's apple pie recipe.
MY homebrew club did an activity that weighed out the same ingredients in kits - malt, hops and yeast - for club members to brew a home, so water and process were not controlled. When judged there was a 20 point spread. So much for a recipe being special.
+1. I've tried several other brewers versions of the Pliny recipe aside from mine - most were good, but WIDE variance there. Heck, water chemistry differences alone (as mentioned) makes a huge difference, aside from inherent differences in systems and methods. I think Denny posted regarding his awesome BVIP recipe that he had tasted many versions of it brewed by other homebrewers, that most were very good, but none were a whole lot like his. I say do the opposite - give them the recipe and see just how different their versions are. A yeast driven beer like a saison will change dramatically depending on fermentation temp, ramp up schedule, etc. Our breweries (and exact methods start to finish) really are unique.
