Default Is my pot causing infection?

Iv used this pot for two batches of beer and 2 batches of chili. Both batches of chili came out great... The beer, not so much. Its turned black inside. Its a cheap aluminum pot. Beer turned out bitter.

You're kettle can't cause an infection. The pot is supposed to be black inside. It's an oxide layer that forms after boiling, and it is a protective layer. Usually you want to boil water in a new aluminum kettle for an hour or so to create this layer. If you didn't do that before you boiled wort in it, then likely your beer tasted bad for this reason. Don't scrub off the black layer!

Pretty new to this myself and I'm sure you'll hear people say to go stainless vs. aluminum, but from everything I've read and brewed so far your pot looks fine. That dark gray layer is oxidation and you want it to protect your beer from the raw aluminum of the pot....that said I've read several times to Never use your brew pots for anything else, especially anything as flavorful and acidic as pasta sauce or chili as it will cause off flavors in your beer

The Stainless vs. Aluminum debate is really just a matter of personal choice. There is no problem with using aluminum. I've made lots of really good beer in aluminum pots. If you clean your kettle good after cooking with it there's no reason why you can't use it for food and for beer. If you cook something so acidic that it strips the oxide layer, then you might have to re-apply the layer by boiling water in it again. I doubt acidic food will even do that, though. If it did you'd be eating that stuff, and if that was the case people wouldn't cook in aluminum at all. It's more of a concern when cooking fatty/oily foods in a brew kettle, but even that is fine if you clean the kettle very well after each use.

Wasn't arguing the Alum/Stainless thing at all, I still use aluminum and all my beers have come out good, so I'm in no great hurry to change and while the taste/cross contamination of flavors issue is anecdotal at best I was just offering up what I had heard and aluminum is cheap enough that I reserve mine for brewing only and take one more variable out the 100 other things I can, and routinely do still screw up😱

I don't use my large kettles for food either. I do have a couple smaller ones that I do use for food and small batches of beer, though.

Since you will never completely scrub the flavors from a pot, mixing food and wort in the same pot will likely cause off flavors.

Thanks for the input. I think my best bet from what everyones posted is just to buy a new pot for brewing only. I am planning to brew tonight so hopefully i can find a new one locally for cheap. I let my pot soak in bbrite overnight, so if i cant find one today i may try to brew in it again until i can order something online. Maybe ill just boil some water now to make sure that oxidation is still there cause i did scrub some off.

Buy another kettle if you want to, or because it may save you the trouble of really meticulously cleaning your pot when you switch from food to brew.

I would simply clean it very well, twice, and not be concerned, at all! Also depends a bit on how much dough you have, and how much storage space you have. But please don't think your kettle is ruined cause you made a batch of chili in it.

+1 I did a seafood boil in mine and then brewed a batch. No issue at all.
