My wife's grandfather used to work there. He told her they each got 2 cases of beer a day. Maybe apocryphal.
those "brewery employee gets X amount of beer free" stories are funny, i think there is some basis to them in fact, as my dad would regularly get cases of unusual labatt products from a labatts manager he knew. stuff like "john labatt's classic ale" and guinness and stuff.
the first beers i ever drank were those ones, as my dad doesnt drink beer. the first beer i was really into was very old guinness extra (5%) at warm summer garage temps, it will always have a special place in my heart.
