very fair point, it is certainly a bit snobby to insist, but why else does everybody like having swingtops, or crowncaps for the beer for example. PET's are bloody useful that is for sure, I am sure somebody said they withstand 100 psi too which makes them incredibly practical.
I don't think I would want to serve the mother in law from a PET, I can just about get away with the winebox. Hell if Mr Berry says its good then I am certainly not one to argue.
Would there not be an issue with excessive oxidation with 2 litre pet and wine... you surely wouldn't be drinking 4 pints of wine in an evening?? it would leave a lot of air in the top after?... ooh just read again what Moley said... feel quite good about that, he knows his onions far better than I
Does the light affect white wines too or anything else for that matter...??? My FV is sat in the kitchen all day, will that cause any negatives?
