I got home from work the other night and the wife said "Hey, Ian - watch this!" before proceeding to bash herself around the head with a bottle of wine.

"This," I thought to myself, "must be a side-effect of staying home with a toddler all day," as I began to consider how I would cope after she were inevitably sectioned.

But just as I was about to pick up the phone and call the nuthouse, I realised that the bottle was in fact plastic.

It turns out that those clever folk at Wolf Blass have begun shipping their "Green Label" plonk in lightweight recyclable PET bottles, to reduce shipping costs. Whatever next? I'd only just gotten used to screwtops.
