Aluminum Boiling Pot

[Morrey]

I am sure this is an opinion based question....Is a thick, heavy bottom aluminum pot suitable for boiling my wort?

At my local home brew store, the owner tells me absolutely NO aluminum pots. It can ruin the taste of your beer, tons of metallic flavor..NO NO NO. Of course he says this as he points to an extremely bright and shiny stainless boiling pot on his shelf. The price tag indicates that if he can sell one pot a week he covers his overhead, LOL.

I have a really nice, clean 5 gallon Aluminum stock pot that is quite heavy. It has a thick bottom and I know it won't scorch the wort as heavy as it is. Should I be concerned in using this pot to boil??

As long as it's oxidized, you're fine. To make sure, just boil water in it, to your expected wort volume, for 30 minutes. Bam, totally off flavor free boil kettle.

 

[Foosier]

It is not a question at all actually. AL pots make great brew pots. I use one and love it..

As 1977Brewer said, just bring water to boil in it once before you use it. This advice is not be brewing specific either, it is just the proper way to prepare a new AL pot for cooking use.

Your LHBS guy has an agenda. Lots of us use AL pots and no one is reporting metallic tastes. Total myth.

Below is an article I think is appropriate. The short answer is it doesn't matter. You will hear both sides of the argument, and this can be a touchy subject for many, but I have used both and can say it didn't give me off flavors.

I have one and it has been no problems. Boil the water first time to oxidize. After my use I just hose it out real well, no deep scrubbing. Don't want to lose the oxidation layer

It's fine to use aluminum. There are advantages to using stainless steel, but aluminum is safe to use. I think that it's in John Palmer's book that he references studies that have been conducted showing this.

I was thinking about Palmer's comments on aluminum (that you sourced, Kee) when the LHBS guy was pushing this SS pot. The LHBS guy firmly swore he could tell a beer boiled in aluminum a mile away. Maybe one day I'll simply blind taste test him and see how accurate he is. But, what difference does it really make...you guys have given me the truth w/o a sales pitch.

Pm me his address. My beers have had their share of issues, but metallic flavors have never been among them.

 

[lumpher]

I use a stainless keggle 90% of the time, but sometimes i do a boil in a 28 qt aluminum pot. No difference in flavor at all. You're correct in suspecting he just wants to sell you the $$$$$ SS pot.

Not to belabor this topic, but where are you guys getting this whole idea of needing to boil water first to prepare new AL cookware? I've seen this come up many times here, and I just can't find any reference to it outside of brewing-related sites (but mostly just this site).

No cooking sites mention having to do this; and John Palmer's metallurgy for homebrewers article makes no mention of the practice as far as I can tell:

Aluminum oxidizes rapidly in air all on its own. I think someone, somewhere on the internet said it once and it stuck.

If you still feel the need to get a SS pot, this is very affordable: http://www.homebrewing.org/5-Gallon-Stainless-Steel-Brew-Pot_p_272.html

Because mine was still shiny after 10+ years as a turkey fryer, and then I probably removed whatever had built up after scrubbing the bejeezus out of it.

Plus I read it here. Makes it true.

 

[Sailingeric]

I read it on here. It was new pot and new burner so I figured I could kill two birds, see how fast it got up to heat and how much propane I was using and do the boil thing.

 

[dstockwell]

Aluminum = no problem..

 

[Jim311]

A zillion people are using old aluminum kegs to boil beer in without any off flavors or problems, myself included. You don't need to "oxidize" anything either. The pot is sitting in an oxygen rich environment, putting water in it isn't going to do anything. Aluminum is tough and cheap, and heavily used in commercial restaurants.

 

[PADave]

I wouldn't even consider using one, and don't use aluminum for any cooking. Just got my new Spike Brewing 10 gallon kettle today.

Boiling water puts a thick visible aluminum oxide layer on the pot that is very durable. Maybe it's not necessary, but it eased my mind to see the dark gray coating on my pot, assuring me that I'm protected from potential off flavors and pitting.

 

[FloppyKnockers]

It's called seasoning the pot, and yes, it's done for cooking too, but if the pot were to be used for cooking it's recommended to use oil not boiling water.

 

[pshankstar]

I've used an aluminum pot for several brews before I landed a keggle to do a full boil. No metallic flavors or anything. Just boiled a full pot of water for 60 minutes (probably overkill) before I brewed a batch. I still use it for smaller batches here and there.

I did see that bit about oil and it makes even less sense. The water works as an electrolyte in the oxidation reaction. The oil does what, and how???

Honestly... I have no clue. Those are the instructions that I got too with my pots.

Here is a thought....maybe its bullsh*t! (not to disparage the fine people who unknowingly peddle such excrement on forums such as this).

 

[tezcatlipoca]

Yeah, I used an aluminum pot when I started and some said that it would cause off-flavors. I presented my bock at a meeting and let them taste it. Afterwards, I revealed it was an aluminum pot. I have since upgraded to stainless but really only because of size constraints. Each one has pros and cons, but neither will cause any bad flavors to a beer when used properly.

Maybe if you brewed a really weak, sessionable beer in an aluminum pot, it MIGHT have a bit of a metallic taste, but who on Earth would brew a sessionable beer on purpose.

Aluminum kegs? Tough? My kegs are steel. Did they used to be aluminum?

But still, I think aluminum should be fine. I do think aluminum is a bit more fragile than steel, but if you are putting a dent in a 1/4" thick aluminum pot, you gotta be brewing wrong.

 

[Terek]

i only use aluminum, mainly because of the price diff. I paid $22 ea for my hlt and my boil kettle. Same one in ss would be $60 ea. I have NEVER had any off flavors from it. The only problem is they dont make them much bigger than 8 gal. so if you are doing 10 gal batches down the road, than you will more than likely have to go with ss.

Your biggest problem is that your stock pot is only 5 gal. You will only be able to do 3 gal batches max with that. Break down, go to walmart, and get a 8 gal aluminum pot for $22

 

[Jim311]

Nah they make aluminum pots way bigger than 8 or 10 gallons, restaurant supply shops, Ebay, Amazon all have them.

 

[MarshmallowBlue]

ALuminum brewin here. No off flavors to report. Like others said, just boil some water in it and don't scrub it.

huh. i just have not seen them bigger. I assumed because as you get bigger, and more volume of liquid, the aluminum just isnt strong enough to support it. I guess they can just make em thicker.....
Id like a 10 gal because my 8 is just not big enough for 90 min. boils for 5 gallon batches
