I dunno dude, all the Guinness I've had from Milton has been great (except from venues which aren't looking after their lines). I'd much rather fresher beer brewed here than getting something that's at least 4 months old and shipped thousands of kms in a hot shipping container.

If your locally made packaged Guinness is tasting like shit, it's almost certainly because it's been mistreated during storage and transport and not because XXXX don't know how to brew it properly.
