Not all of us do; however, our excitement over the process does tend to leak out even if we're trying to keep it contained. I know I try not to ask questions that would be only relevant to a home brewer. I do ask questions about hops or gain in beers not because I home brew, but because I am usually trying to nail down a taste I did or didn't like. I learned about not loving beers with black patent malt in them by doing just that. There are also hops I do not care for or favor and tasting a beer that had such presence, I would be inclined to ask. I am not asking anyone to talk shop with me. I'd do the same thing at a restaurant.
There may be a case where that is true; however, this guy said it was proprietary hop blend. Either way, if he doesn't want to tell anyone, that is his right. My guess though is that he may not have known or really didn't care to share it because he knew it wasn't awesome. I'd want to know because I would avoid mixing those hops.
This brew pub started off on the wrong foot. I paid $20 to go to their grand opening which was a parking lot fenced off with a band in the middle of June. There were about 7 people inside those gates. After spending $20 to listen to a band that I could have listened to from my truck in the shade, I also paid $15 for 3 tickets to buy beer. Turns out they had never even fired up their brewery. I was paying for crap I could get at the restaurant I went to eat at 30 minutes later. I went back with about 10 friends and drank there, got a tour because I was with another brewery, and learned that asking questions about their BCS brewery seemed to be more of an annoyance to the owner than anything. Still, I bought a cap because the hottie who got me into the brew house was well, hot.
I am glad to see they're at least brewing something. I'd give them another shot but their grand opening was a bit of a flop in my eyes.
Point being, every new brewery deserves a second visit unless there was something so incredibly horrible about the first visit that I cannot stomach another visit.
