Stone & Wood don't do brewery tours. It's a working brewery, and you'll find they're far too busy brewing actual beer to entertain the OHS issues of inviting random sticky-beaks in for a looky-see. No eye candy, either.
Go round the corner to the old Piggery, which is now the Byron Bay Brewing Company. Just look for signs pointing towards the Cinema. They _will_ do brewery tours, and have a decent range of beers on tap, but far inferior to S&W, imho. Their beer garden is nice, though, with a lovely 100 year old fig tree, and plenty of eye candy.
Get to the Rails (Railway Hotel) for good, fresh, S&W Pacific, or S&W Jasper ale. They've also got a decent range of other stuff, LCPA, etc. Also, eye candy.
It's Byron, just about everywhere has eye candy.
