Cullen: cork goes against green principles
- Monday 13 September 2010
Cullen, managing director and senior winemaker at Cullen Wines in Western Australia’s Margaret River, says the use of natural cork is ‘unacceptable’ – for any wine.
‘For me, the screwcap wins over cork every time’, she says, setting out her objections in some detail.
She says the impetus for her guest column – in the October issue of Decanter – was a library tasting of 30 years of Chardonnnay at Cullen to mark the anniversary of producing the grape at the winery.
‘With great excitement I sat in front of 30 years of history,’ she writes, and is delighted by the 1982, ‘which is still alive with golden tinges and some lovely citrus fruit’.
But her pleasure is short-lived: ‘With the exception of 1997, 1998, 2000 and 2001 – the rest of the wines under cork had descended into the grave.’
The problem, Cullen says, is oxidation and cork taint.
Interestingly, given the natural cork lobby’s use of environmental issues to plead its cause, she considers the risk of using cork antithetical to the principles of modern organic winemaking.
‘To deliberately kill wines with cork taint or the possibility of oxidation goes against the culture of biodynamics. To introduce a random winemaking influence by the addition of mouldy cork just doesn’t make sense.’
Her final argument is that the use of natural cork is anti-green, because all the energy used to make the wine – ‘all all the things which contribute to our carbon footprint’ – is lost to cork taint.
Therefore the screwcap, which might use more energy in manufacture, is in fact ‘greener’ than cork because ultimately the waste is less.

last night opened a bottle of 1962 chateau la tour du pin figeac - it had a green moldy cork - not sure it is even good for cooking...what a waste! the austrians made several wines w. glass corks!

I disagree with her green-reasoning but I agree with her backing of the better quality control of alternative closures.
There was a period of years not too long ago where Australia and NZ were regularly written off and provided with the poorer quality corks from the manufacturers. Consequently the manufacturers have only themselves to thank for inspiring a movement against cork in Oceania. We were only going to sit around and be dudded for so long before we investigated locally available quality-controlled alternatives. It took a while for them to realise the market was slipping through their fingers and had to smarten up their act - by that time the train had already left the platform.

The amount of aluminum in a Stelvin is probably less than a tenth of that found in an empty beer/soda pop can, which also has a plastic liner/barrier to prevent contact with the liquid. Why not go after those who help create billions upon billions of those cans annually, w/only a small fraction of recycled?
So far, I've had at least 30 bottles of a favorite (go to)'05 wine (under screw cap) $28/us in the past two years with each one almost identical in its flavour profile to the first. How many of you can say that about your "corked" wine?
Was Dr. Chris Exley's "doctorate" granted in the field of Existential Phrenology or is he simply suffering from advanced onset Alzheimer's? And wine is not a truly living thing regardless of whatever "terroir" slipped into the bottle but an ever-changing complex chemical reaction subject to what went in at bottling and all the "terroir" surrounding it from that point on. Me thinks too many Decanter readers have a closet fetish for the smell of old women's shoes or worse.
Grapes are fruit, wine is fermented fruit juice. If you manipulate it enough you get bad cognac or worse. Has anyone out there revisited the tenants of scientific method recently or do you get off talking out of your arses?

"Her final argument is that the use of natural cork is anti-green, because all the energy used to make the wine – ‘all all the things which contribute to our carbon footprint’ – is lost to cork taint."
I disagree. The energy/carbon footprint is already there by the time the wine is bottled. You can break the bottle as it comes off the production line or drink it after 10 years - it makes no difference as those are sunk costs. In fact breaking it immediately after bottling would be better for the environment as then the incremental carbon costs of transport, storage etc. would not be incurred.
