I wasn't going to do it but you provoked me...
Well actually...boiling the wort for an extended period of time increases the concentration of sugars and flavors leading to a stronger batch. It also allows more Maillard reactions to take place which darken the wort and add even more flavors.
well, actually... it would make a darkER beer, not necessarily a dark beer. the way ChshreCat told it, seems like the guy said that's the way ALL dark beers are made.
so, how long would it take to boil a pale ale into a stout?
