ok....i've just finished brewing my third extract beer and again it is very dark. so far i've tried american light ale, belgian wit beer, and a lemon heff. the first two turned out darker than i expected them to be....a lot darker. the last beer i paid attention to the wort as i was boiling my bittering hops and it gradually got darker and darker. i'm sure there is some scorching going on. i try to stir it as much as possible, but as opposed to coninuously stirring for 60min straight, are there any suggestions to preventing this darkening of my beer. i use a stainless steel pot and cook on a gas stove. thanks.
