Haven’t mentioned the juicy subject of wine bottle closures around here for a while.
I’m seeing more and more Diams – the technical cork that’s made from fragments of cork cleaned from any contamination by supercritical carbon dioxide. In a new move, I’ve encountered my first Diam (in a Bordeaux white) that guarantees on the cork to be taint free: ‘the only cork guaranteed without cork taint,’ it says, on the cork itself (above). Diam comes in a number of different oxygen transmission rates (OTRs), and is a really useful closure.
And Nomacorc, the world’s biggest manufacturer of synthetic corks, has just released a new product line. One of the problems with synthetic corks in the past has been their aesthetics. The new ‘Select’ series solves this: it’s a beautiful-looking closure, with a nice chamfer (the smoothing of the edges of the cylinder), a wood-grain effect on the sleeve, a very clever end-grain effect, and also end printing. It’s really attractive. As for now, the OTR is the same as the existing Nomacorc products (that is, reasonably high, which can be good for some wines and not good for others), but subsequent products in the select series will be taking the OTR rate down quite significantly.
