Back when I moved to all grain brewing, I bought an inexpensive (read made in China) stainless brew pot so I could accomplish a full boil. When it arrived it had a couple of small blemishes but it seemed OK. Inside the pot, a grinder had been used to smooth the spot weld where the handles were attached. One of the grinds looked a little deep but since I didnt know at the time if I would be sticking with all grain brewing I let it pass. Once I tried the all grain method I never looked back and have been brewing with this kettle for a number of years now with no problems in the spot weld grind areas. Recently, I started experimenting with the No Chill method and so the wort remains in the brew pot overnight at a level above the grind marks. Now, Im beginning to notice the flaw in the stainless steel at the deep grind spot seems to be getting larger and showing as a black blemish. No rust stains or anything but Im beginning to worry I might be contaminating my beer with heavy metals or something.
Do any of you stainless steel guru types out there feel like this might be poisoning the beer?
