Homer, I totally understand wanting your local brewery to brew fabulous beer and you see that they aren't and know that they probably fairly easily could be; trust me, I feel your pain. I get it. I get it.
My local brewery, which I need not name, used to make fabulous beer and was starting to attract a lot of attention. Then a brewer left, then another, then another. Now the brewer is a kid who just happens to work there, because his dad happens to work there, and his grandfather. He follows the recipes, does what he is supposed to and when there are taste issues, it is always his fault, all for 11 bucks an hour. While no one doesn't make a mistake, most are easily traced to sanitation problems in the cellar department, should they bother to look. But it's easier to blame him and step on his wage at the same time, rather than to find where the issue is and make sure it doesn't happen again. The current brewer is just there for a job now and not happy, and not being paid nearly enough to keep him for long. He has no real incentive to fight the system to make the beer better, for all the head banging on the wall he could do, the owner is consistently lessening the grain bills, lessening the flavor/aroma additions, and dramatically lessening the dry hopping.
So the owner is his own worst enemy; the morale is as bad as any place could be, and while economic conditions depress pub business and off site sales, the reaction to those issues is an exacerbation of those very issues, with the result a continuing spiral of poor customer experience, and lower sales.
Sure I could say something, sure I could back it up, sure I could present it positively, proactively, and politely, but the fact of the matter is, he don't want to hear, he is never wrong, and I have been thru the 'Who are you to tell me how to run my business' when I was younger, and I figure I am not the going to be the one ever again, unless I'm asked, and even then I'll have to consider it for a long, long time. It's the proverbial 'stepping on his own dikk'. The bottom line is that the guy-in-charge's personality filter's thru-out the whole place; either that personality allows a culture of constant improvement or one of constant obedience; it don't work both ways, and that's all there is to it.
I have gone there and not been happy for a long time, and go less and less, but still having personal ties there, and knowing what the beer once was, I've been optimistic long past any reason to, and am slowly but surely just throwing in the towel and trying not to think about it much anymore.
I get it, dude, I get it.
