So this thread has been interesting but I guess I sucked it up on the OP.
My actual question is more along the lines of this scenario: You have a 1bbl brewery. You contract a 10bbl batch of one of your recipes. The contract batch goes through a more commercial process than your own batches on your 1BBL. If they did not taste the same, what would be the leading causes as to why?
could be several reasons I can think of off the top of my head.
Repeatability. Making that same 1bbl batch x10 on the average homebrewers' rig would be an interesting feat. Some of these guys have a nearly automated rig, and would (in my opinion) stand the best chance of making a repeatable beer x10. My rig is not automated in the slightest, and I admit I'd have a heck of a time doing that. It would only take a few changes in any of the variables involved in brewing (not just the 'hot side' but even and especially during fermentation, packaging etc) to make one batch taste a little different than the next. This is a very bad thing for a commercial operation -the average beer drinker expects consistency -and frown all we might, fact of the matter is that even a beer novice can detect changes in flavors bottle to bottle.
Keeping everything the same, start to finish, is a daunting task and well beyond most (certainly beyond my capability) but the closer you can get to that, the more consistency you will see.
Now, when >I'M< going to brew a 'large' batch, that will be available in one sitting (like when I am bringing several kegs of brew to a motorcycle rally) I will usually blend the wort prior to pitching the yeast, and pitch the same amount of yeast per fermenter (eventually I will acquire a larger fermenter, one that will fit in my keezer and that can hold about 20 gallons) -this goes a long way toward allowing me to at least appear more consistent (since arguably, its all one big batch, which is then kegged and carbonated off the same manifold).
I do hope this helps.
