While it is too early to compare taste, I see the difference between extract/mini-mash and AG right on the first day of fermentation. This is my first AG brew, and it has the best looking (out of 13 non-AG brews) kraeusen. Hard to explain, but it just looks much better - shiny and full of inspiration Here are some pics, first through the peep hole, and the other one with the open door of my chamber.
