We were with some friends last night and amongst other wines opened a 99 Deydier CNP. It was unfortunately somewhat bretty. I know the plastic wrap treatment has been discussed relative to TCA, but I was curious about brett.

Well, at least on this bottle, it worked, at least to a degree. It definitely pulled the brett out - much to the amazement of the crowd. It was hard to tell if it had also stripped out anything from the wine - it was good afterward, but not great, and somewhat sub-par from what I would expect from a good 99 CNP. But it definitely made something that was undrinkable into something that was at least enjoyable.

You raise a good point. 4-ethylphenol, one of the culprits in Brett infection, should be quite lipophilic and hence a good candidate for polyethylene extraction. Some of the other baddies produced by Brett are anyone's guess.

I don't work in a lab anymore, but Professor Lipton, let's do a little experimentation. Water solution of 4-ethyl phenol, get an HPLC trace/integration and then run a sample after giving it the old plastic wrap treatment. Unless you've got a more elegant way of doing it. (Less than 2 months out of the lab and my scientific brain needs a scratch! Still not regretting my decision to leave the lab, though -- 7 nights a week in my own bed is soooo worth it.)

Cheers,

Kevin

Sure that you don't want a bench to do this experiment, Kevin? You'd have to control for other factors such as evaporation of solute and solvent, oxidation, etc. But it could be done.

I wouldn't mind having access to a bench, but it depends on how far I'd have to commute for it... I wasn't necessarily thinking about this being too good of an experiment. The boiling point of 4-EP is 218C, so don't need to worry about that one too much, and water, you can determine by weight. You want me to eliminate ALL of the variables, what are you, some sort of scientist? (insert happy combination of punctuation)
