i've got a mate who's a head brewer for a commercial micro brewery (yes, i can feel you all winceing...

) who has advised me to rack the beer to secondary fermentation once the SG is around 1015 (ie before fermentation is completely finished). he is suggesting moving the beer to a cool place to stop the ferment (at around 1015). apparently this leaves some residual sugars for the secondary once you transfer to keg, moving the keg to a warm place for a couple of days to kick start the secondary. the beer is then ready for drinking after about 5 days of stillage/clearing. he adds no additional sugar for the secondary at all.
apparently this is how he does it, but we are talking on a commercial scale here.
has anyone out there tried this method and if so, how did you get on?
thoughts, criticism and brick-bats welcome!
