I agree with the previous statement about the experience and knowledge of the brewer. I apparently have a way of getting onto the brewing floor, many times with the head brewer, at nearly every brewery I visit. It truly amazes me at the lack of knowledge I occasionally encounter. Combine that with a poorly trained palette and the willingness to push every beer out the door regardless of quality, and you'll get a multitude of issues. I also see at breweries that I visit, and where I've worked, a lack of knowledge and commitment to a good balanced draft system. Beer lines too short, one pressure across all taps, no regard for reserving certain taps for certain styles. So you end up with a server pouring two pints of beer to fill one glass. And after all that foam has settled you have an under carbonated beer. My last brewery simply had a catch bucket under the tap tray. After a busy night that 5 gallon bucket would be full. And we were selling out of beer sometimes in two days. Lost revenue, down the drain. That extra money could have fixed the draft system. But it's hard to get an owner to spend when margins are so very small. And then you get the herd hyping a place, along with the Instagram self promoted hype with the purchase two thousand followers, and people think this poor product is great. Kinda like the emperors clothes.
