First of thanks to all of you guys for helping me out with my home-brews. I've been lurking this site for a while taking on board the valuable advice you've shared with others and it has helped me no end!

My main questions(s) concern my recent employment as an assistant brewer at a local microbrewery (hooray for me!). The head brewer has been there for 15 years, is self taught and a bit set in his ways. Recently; however, a considerable amount of their product has been returned - the main reason being undesirable fermentation during cask conditioning, effectively "rotting" the beer as one customer put it. After my first shift there I had a sit down to think what the problems may be...
I recently graduated uni with a BSC hons in microbiology so understand a lot of the more technical science behind brewing and the conclusion I came to was that the dead yeast was not being skimmed off during fermentation, becoming infected, depleted yeast = less CO2, infected yeast sinks back into brew, sediments at bottom of FV and is drawn off into the conditioning tanks and eventually kegs creating the problem the head brewer faces now.
The brewery itself is dirty. I can appreciate that the head brewer set it all up himself and all and all the equipment and vessels are cleaned thoroughly (I think) with detergent and paracetic acid (at different stages). The walls of the brewery are covered in mildew, there is mildew on every window, around the sink, around the fridge, the yeast incubator has seen better days, packaged malt is stored right against the mildew coated walls. Basically if this were my brewery I would shut it down, clean, re-paint, replace equipment etc.
Would it be appropriate for me to mention to the head brewer and/or the establishment manager the problems I think exist so soon into my employment. Oh and if anyone has a different hypothesis concerning the spoiled brews that would be greatly appreciated!!
So sorry about the wall of text!
