I brewed my first batch ever from an extract kit by brewers best last night and it's bubbling away in the fermentor now. I used a stainless pot on an electric stove and after all was done I noticed some burned on residue in the bottom of the pot that follows the design of the burner underneath it, had to scrub it out. Is it normal to have a little burnt on the bottom? Will this effect the flavor of my beer? Thanks.
