Cork

An article from the UK’s Telegraph about France’s Cork Federation and their recent campaign to boost cork appreciation got me thinking. For one, about how little I still know about corks, and for two, about how much I do know. For again and again I have been hearing about the two camps, to cork or not to cork, because of the fear of what’s being labeled cork taint. Supposedly cork taint can affect up to 15% of all wine bottles, no laughing matter. But how much is really cork taint from corks, and how much is it from other sources that rarely get referenced?

Because what I have hardly EVER seen or heard mention is that corks are not the only culprits of this so-called cork taint. There are other winemaking sources that can lead to this wet-dog delight: Try chemically treated wood products when they come into contact with chlorine-based cleaning agents. Try naturally occurring fungi coming into contact with same chemically treated wood products. How many wine places have you been in where the storage of boxes and pallets and barrels and beams are all within wine reach? ExACTLY. And yet it’s the cork that continues to get blamed.

The other thing is that not all corks are created equally, and some will be better than others due to quality issues. Period.

Bottom line is, not all cork makers are the same, and there are other sources for what has been unfairly and categorically dubbed cork taint. So how ridiculous are statements from the big influencers when someone like old James Laube says, “Over the years, I’ve had too many wines and wine events ruined by bad corks.” What, does he own stock in the twist-off biz? And he’s not the only one to make blanket statements like that. I know, I know, everyone has their own agenda when they write, that’s clear. I just wish there’d be less dumming-down out there and more truthful and FAIR reporting. I’m sure some reading this will think, “Put a cork in it, LaMonica.” And to you I respond, “Why thank you, I will.”

  1. While it is true that there are other sources for taint, it is also true that corks do contribute largely to the problem. Besides your named potential sources, don’t forget any winery using city water is sure to have a “background” problem. Any winery operating today that doesn’t routinely run tca/tba analysis on their pre-bottled wines is living in a fantasy world. This is important because if you have a background level of 1-1.5 ppt and you buy corks that at the best the industry states they can do of 1ppt, then you have just pushed your contaminant level above the threshold. Furthermore, any winery that believes the tca/tba analysis sent to them by their supplier (even if it is from a third party lab) is likewise either ignorant or in denial. I have witnessed many bags of corks coming from reputable suppliers with ets labs numbers of 6ppt! And yes these were top of the line, super premium supplier corks. If you can’t show what your background levels are and what the levels are in each cork shipment, then you owe your costumers some serious apologies.

    Bottom line is, any winery that doesn’t take responsibility for using a product that the manufacturer admits they cannot make completely contamination free is ripping off the consumer. Why pay for a product that you know is potentially defective (well i guess it worked for microsoft).

    And don’t even get me started on oxygen transmission variability of corks, leaker corks, ot rotten corks.

  2. yes, yes. but the other culprits, however, do need mentioning whenever taint gets referenced – from an educational and fairness standpoint. while it may be the cork, it may be other things, and people need to know that, too.
