Storage in aluminium

Storage in aluminium

Postby Beast » Tue Dec 18, 2012 3:13 am

I want to get rid of my 3 gallon demi john for storing 180 proof. Glass doesn't rock my boat. Unable to find any stainless vessle locally, I did find someone who is selling 5 gallon aluminium drums, previously used for milk.

Is aluminium good for this, or should I look further for stainless steel?

Most of aluminum's trouble comes from its acid resistance, or rather its lack thereof. Aluminum leeches into just about anything acidic. Most mashes we do are pretty acidic so we don't want to use it for boilers where it will be corroded and eventually destroyed.

That said, it should be non reactive to distilled spirits.

Hi David, these were my thoughts exactly. The guy only asks for a fiver as well, I'll pick one up on my way home. Thanks

Have to ask, why are you storing such high proof in the first place? :o

I don't usually have anything over 60% ABV kept anywhere. Just for safety / fire prevention reasons.

I dunno, easier to store and for the ease of handling my recipes I guess. Is there a big difference between a 120 proof or 180 proof fire?

Well flash point of 120 proof is 22 deg C where 180 proof is 20 deg C, and the lower explosive limit is 3.3% by volume in air, so possibly not a huge difference in the scope of things.

And it shouldn't be anywhere where it could be consumed by accident anyway.

I just remember that once I brought back a bottle of Bacardi 151 from Cyprus, and the crew insisted that it be transported in the hold as Dangerous Air Cargo and not in carry on luggage. Hate to think how they would regard it these days!!!

So provide you treat it carefully it should be OK. :)

I've never heard of aluminium being used for milk storage? I find that odd?

Some fire extinguishers are stainless. :wink:

It's easy to pick the stainless from alloy as they have weld marks and are lighter when empty.
