I don't want to become known as the closures guy. But, having said that, it's an important subject, and I'm keen that the wine trade makes some wine choices at this fork in the road we are currently negotiating. So I'll continue to write about them, for the time being.

One of tonight's tipples is a pleasant, affordable New Zealand Pinot Noir from Stoneleigh (Waitrose £7.99) that has supple, rather elegant cherry and red berry fruit. Not thrilling, but pretty good. However, the reason I mention it here is because of the closure. It's the new Stelvin Lux. Rather than being an aluminium cap which is then clamped down, with rollers forming the screw thread against the surface of the glass (which results in a thread evident on the cap), Stelvin Lux has a plastic thread inside it, which means that the screwcap has a smooth finish. It's a cosmetic change, effectively. And perhaps at the cost of some performance? How robust is this, given that the plastic thread is an extra component in the cap? Will it be effictive in holding the wadding tight against the rim of the bottle?
