have to cast yeast - again ARRRGGGGHHHH

[CR]

big picture, and despite wildly different scales, pro brewers and home brewers both do the best they can with the equipment they have

One can only do the best one can.
Vocational brewers have such a large armada of tools techniques and chemistry to play with but (and I think it's a huge "but"), home craft brewers have a much more intimate relationship with their brews.  The  guys  in the Sam Adams commercial can  talk about commitment but no matter what - at the end of every work day - they have a quota they must meet and it is an unforgiving thing.

If I get a  notion that I think this ale could do with a longer conditioning ferment and maybe even a dry hopping then  I get to do it and no body can tell me when I gotta bring  my beer to the bottling station.
