I posted a few days ago on an article in a trade publication based on an MW dissertation by Alison Eisermann-Ctercteko that examined the extent of screwcap damage in the retail chain, and the implications for wine quality. This caused quite a storm, because it claimed that 26% of all caps showed some physical damage, and over 8% [...]
The rise in screwcap use in Australia since 2000 has been remarkable. Now they are by far the majority closure, for fine wines as well as more commercial ones. But a Masters of Wine (MW) dissertation by Alison Eisermann-Ctercteko, which has been published in Australian trade publication Wine and Viticulture Journal, presents evidence that is [...]
A scientific paper that has just been published in journal Proceedings of the National Academy of Sciences (PNAS) examines the way that 2,4,6-trichloroanisole (TCA), the key compound responsible for musty cork taint is perceived. The results are surprising.
They suggest that TCA acts on olfactory receptor cells (the cells containing the proteins that detect smells) by suppressing protein [...]
In short, no.
I have just written up Tuesday’s presentation and tasting on the results from research carried out by Bordeaux first growth Chateau Margaux. This was presented by Paul Pontallier, and he displayed an incredibly open and thoughtful attitude in sharing details of the in-house experiments that have been going on there for a decade.
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 [...]
I had a meeting this morning at Clarence House, the home of the Prince of Wales, so afterwards I wandered down to take a peek at the ‘Start’ Garden Party to Make a Difference, which is being held over the next few days here (see the website for more details).
The idea of Start is to [...]
A question. Why is it that the beer industry is happy to use crown caps with PVC liners for bottled beers?
These PVC liners allow a high level of oxygen transmission. This reduces the shelf-life of the beer, and also means that the same beer is experienced differently by consumers depending on when it is drunk.
Opened a Trimbach Riesling this afternoon to find it had a new-look Diam (taint-free technical cork) in the neck. This Diam has been streaked with brown to make it look more like a natural cork. Will this aid consumer acceptance, or is it actually unecessary?
Coincidentally, the day after I returned from Planet Zebulon, where I’d been visiting Nomacorc’s headquarters, The Wall Street Journal ran a feature on the way synthetic corks and screwcaps have taken market share away from natural cork, focusing strongly on Nomacorc. You can read it here.
The article is pretty comprehensive, and contains an interesting graphic [...]
Nomacorc is based in the wonderfully named town of Zebulon, which sounds like something from a Flash Gordon movie. I spent the day here yesterday, visiting Nomacorc’s headquarters. I have just a few minutes to blog, so I won’t go into any great detail, other to say that it’s a big operation, with 10 extrusion [...]
