Regular.
It may be because most bottled beers are not live but pasturised and filtered, and you prefer cask/bottle conditioned. There's a recent thread discussing this http://www.thehomebrewforum.co.uk/showthread.php?t=68119
I also wonder how travel effects beer. Does our HB tastes better than pub offerings because it only travels a few yard around our home from FV to glass? Wheras commercial beer can travel hundreds of miles. Does yeast not like to go far?
Yes very good points?
Much like people say pasteurised milk is no comparison in flavour to unpasteurised.
There could also be issues with tinkering to increase profits.
10 min shorter boil here, some sugar added there, thinking nobody will notice. But the small changes add up when put together.
