It’s on Sat 18 July, same wines closed with screwcaps and corks will be opened and compared in a blind tasting. Unfortunately I can’t attend, is anybody planning to go and report? I would love to hear about this.
Any other winery doing the same kind of experiment?
Kathleen Inman bottled her 03/04/05 OGV pinot with a combo of cork and Stelvin closure. I’ve yet to have the chance to make that comparison, but she has mentioned that the Stelvin wines are much fresher/brighter when compared to their cork counterparts.
South African wines are not the only ones she has detected with grievous faults. A few months ago, she tasted “a whole slew of supposedly top-notch” Marlborough sauvignons from New Zealand. These wines, she wrote, were not only “watery” and “grassy,” they were “evil.”
Harvey Steiman at WS wrote up a tasting he attended about a year ago where at least 8 of the 10 or so vintages under screw cap and cork from Plumpjack were tasted side by side with the folks from Plumpjack . . . From what I remember, the younger cabs were quite different - with those under screwcap more primary and vibrant; the oldest ones were actually quite similar to each other (cork and sc) . . . You might do a search of this.
Mike Officer bottled a zin IIRC under SC and cork a few years back and sent off matching sets for people to compare/contrast. I know ‘the other board’ had many a note on these . . .
Would be a great tasting to go to at TC - do you know how far back they go with both closures? Wonder if they’ll have anything older than a year or two . . .
Many winemakers accept noncork closures for whites, but what about reds? Trials have been going on in cellars around the world, with differing conclusions. Paul Draper, chief executive and winemaker at California’s Ridge Vineyards, has been testing alternative closures since the early 1990s and has rejected all of them so far.
“We’ve found that plastic corks and the Vino-Seal allow in too much air and cause the wines to age too rapidly,” he says. "Conversely, under standard airtight screw caps, the wines hardly age at all, whereas with cork the wines develop the complexity with time that we’re looking for. We’re not sure how, but it seems some air penetrates the cork or is released from within the cork, making the wine more complex. We haven’t yet found a closure that will do that better than cork.
“We test all our cork samples very rigorously and often reject batches. Nothing’s foolproof, but we’ve kept cork failure down to around 2 percent. We haven’t tested Diam because a conglomerate cork is not really a cork, but we’ll keep looking at anything interesting that comes down the pike.”
By contrast, Henschke says the first reds he put under screw cap in 1995 “have developed beautifully. They do age more slowly than with most corks, in the same way wine ages slower in a bigger bottle like a double magnum. It’s a misconception that wines need extra air through a cork. In fact, French research from decades ago showed that wine ages better without additional air, and the AWRI’s recent research has shown that the best corks act just like a screw cap, by keeping oxygen out.”
