The theory is that oxidation reactions happen much quicker at high temps and the damage is done before the boil.

Lowes/home depot carry reinforced hot water hose for like 25 cents a foot!


I've laudered 15 AG batches with this hose, never an issue.

I've used these as well, haven't had an issue other than the fact they do not bend very well.

Even if these braid-reinforced vinyl tubes have held up well, they are still vinyl. This means you are still leaching potentially toxic chemicals into your beers when siphoning wort that is 100F+

If you are okay with that, then no worries. But the healthy alternative is a $10-15 section of silicone tubing, temperature rated up to 500F... easy fix to avoid some long term damage to your body.

My theory is IF there were potentially toxic chemicals leached from my hose...it all came out in the first batch.

Pretty sure this type of hose is used to feed hot water to dishwashers and coffee makers so it is likely food rated or at least not proven harmful enough to prevent it's use for potable water.

I just figure I am killing my liver enough as is with my homebrew, if I can spare it some other harmful chemicals at minimal cost, why not?

Either way, RDWHAHB! After a few, you probably will forget what you were trying to figure out in the first place.

You're confusing "oxygen" with "oxidation." Oxygen is an element (and yes, any introduced during mashing will be driven off during the boil), oxidation is a reaction. Once the reaction has occurred, boiling won't "undo" it.

I use this stuff http://www.northernbrewer.com/shop/brewing/brewing-equipment/siphoning-equipment/tubing/high-temp-tubing/3-8-id-thermoplastic-tubing-1.html and although it withstands heat very well, it is terribly stiff which makes it unwieldy IMO. I would like something less stiff and haven't been able to find it.

They also have a 1/2" diameter size. Done!

It may be a little more expensive but it appears that it is totally worth it. Ordered 5' today along with supplies for an IPA... cheap shipping and timely delivery... THANK YOU AHS!
