I'm betting on chlorine/chloromines. That's where it usually comes from.

I still think it's a bacterial contamination but using non chlorinated water and being extra careful with sanitation would be a win-win.

What does everyone else think, any chance that at those temps the plastic smell leached into the beer? I read on the web site that the braided PVC tubing is non toxic, so I'm guessing it's still safe to drink. FWIW, the plastic smell I perceived has diminished quite a bit from when I first kegged this batch. In addition, I took a sample to the LHBS and let them try it and they both didn't notice it, only the hops (it's an IPA).

I've had this before, mainly with lighter-coloured beers (0-10SRM). Didn't happen with my darker stouts and porters.

Solved it with 1/2 campden tablet the night before I brew 'er up.

I would say try cleaning all your equipment, see if you get the plastic taste again, if so then change the water aspect. If you do both at the same time you won't know which is actually the problem. IMHO.

What kind of sanitizer was used?

Stay simple at first - begin by attacking the more obvious targets.

Early last year I went from using One Step to Star San and my odd flavor issues went away - I had a strange taste that I couldn't really put my finger on either - but after this switchup, I've been consistently brewing great beer. I hope it's a similar situation for you.

You might even consider scaling back and brewing smaller batches until this is identified. There's nothing more frustrating than brewing five gallons and not even being able to cook with it.

Its pretty hard to infect a beer, you almost have to try and cause it to happen. If this beer was on tap and you had this taste as a regular problem then you start thinking about contamination. However, given its bottled the chance that it is infected is pretty low. As a side note from looking at your hoses and removing possible sources of chlorine, I have encountered this with dry hopping as well. I was discussing a beer with the head brewer of a brewpub chain that had a polyphenolic character to and he said that the brewer had a habit of dry hopping the serving tank and he believed that to be the source of the off flavor. I thought this interesting as the only time I have got that character from dry hopping is when I put it in my cornie and let it sit too long.

If it's happening over and over again and it happens only in your light beers, it's a chlorine/chloramine issue. It definitely gets worse over time. You don't notice it drinking the water fresh from the faucet but you're also not drinking tap water mixed with alcohol and other biological components and you're usually not drinking your tap water after it has sat for weeks or months.

Try using bottled water for a batch of light-colored beer using all the same equipment. See if the problem goes away.

what he said ^^^

i had the same issue with all my brews till i went to spring water.. problem solved...
Tons of phenols in the water.
