As soon as they scale it up to pro scale, you'll find that malt ratios change, hop utilization changes, extraction efficiency changes, etc. For example, your carefully tweaked amount X oz of XYZ malt gets rounded to N sacks (where N is a whole number) and your hop measurements get rounded to Y lbs. Your mash hop regimen gets changed to a FWH addition because its too expensive and it chokes their mash tun.
All it takes is just one or 2 of these changes and it really ceases to be yours and becomes their recipe anyways. Don't sweat it. The long lost "von Wolfhausen family recipe" like you see in Beerfest doesn't exist.
