Decanting - The Answer for Hidden Terroir!

In a recent piece over on Appellation America Dan Berger wrote the following

“one of the key factors in all great wine - evidence of the terroir - is easily obliterated early in a wine’s life, and the only way to access it is to decant the wine and allow air to work its magic.”

OK Dan, I’ll bite. Before you arrived at this enlightened moment of wine truth just how many wines did you find that revealed their terroir following decanting? And by that I mean performing a triangulation test with one bottle decanted for a few hours compared to a freshly opened bottle?

I have no doubt that Berger is correct in saying that some wines can exhibit sulfur (and other) odors soon after a cork is pulled or a screwcap ceremoniously removed in the Helm manner. And these odors can mask the depth and complexity of the wine. But for exposure to air to reveal hidden terroir is bunkum. Just like any other aspect of wine lore aeration produces effects that can be entirely subjective. If you don’t believe me get a couple of bottles of one wine and a few friends together and do your own triangulation test.

What is a triangulation test? In essence it is a test to see if a taster can distinguish between two wines (or as I have used in decanting experiments here on SHIRAZ - decanted versus non-decanted wine). Two glasses receive one wine and a third the other wine. It is the task of the taster to identify which glasses contain which wine. And because two glasses have the same wine it shouldn’t be all that hard, right Dan!

On the Internet Vine

Being too busy with non-wine related work at present I can only find time to post on a couple of interesting little gems from the internet. I know they are low hanging fruit, but sometimes that is all there is time to pick!

I guess we will have to wait to see how big the hole is that Eric Asimov has dug for himself in his hasty criticism of "The Wine Trials". I'm sure it was a little bit unnerving to find not only have you dined with the target of your venting, but that the study in question has actually produced a scholarly article. It really is time for everyone to take a step back and wait for the book to make its way into the hands of interested readers.

On another tendril of the internet vine Dan Berger seems to be coming around to the idea that our genetics may contribute to our appreciation of wine and influence the wines we prefer to drink. Maybe this is the first step on the road to allowing all wine drinkers to drink the wines they have a preference for. That would certainly be preferable to attempting to impose ones’ own preferences on others.

A note to Dan Berger (and the rest of the anti-high alcohol league),

After several attempts to post a comment on Dan Berger's latest article on high alcohol wines, and getting the message of an error on the page, I've decided to post my thoughts here. Maybe they will take my comment later?

Appellation America is directed toward a very small segment of the wine drinking population, so I wonder how much thought you or any of the other writers on the “big wine” topic give to the average wine drinker. Is it in the interests of the majority of consumers that appreciate the riper style of wine that you pen these articles?

There are an additional few questions I would like some data for, and no I don’t want dogma or anecdotes. Let’s put some meat on these bones!

1) Where are the studies showing that there is a correlation with the popularity of high alcohol wines and cola drinkers? (Just pose that possibility to the average Australian wine drinker and see what answer you get).

2) How many wine drinkers buy wine so that they can determine the regional characteristics of a wine? (Do you really believe that Mr/Mrs Average Winedrinker is at all interested in regional character when they drop by their local wine shop to get a few bottles to serve at their dinner party?)

3) More to the point, how many wine drinkers can actually identify regional characteristics in a wine?

And finally,

When is the anti-high alcohol league (Corti, Dunn, Asimov, McCoy, yourself and others) going to attempt something constructive in terms of addressing alcohol levels in wines? No, the diatribes that have been written thus far are not constructive. They are destructive, divisive and elitist. When will any of you judge these wines blinded against food? Wine has been judged this way at The Sydney International Wine Competition for the last 26 years. (Just as an FYI, the 2007 winner was the 2004 Neagles Rock One Black Dog Reserve Cabernet Shiraz. At 15% alcohol it came away with best Fuller Bodied Dry Red Wine, Best Red Table Wine of Competition, and Best Wine of Competition.) When will any members of the wine press pull together both sides of the argument to discuss alcohol and balance in wine as the Wine Press Club of NSW attempted in July of this year? If winemakers believe that less ripeness and lower alcohol levels will be popular with the cognoscenti then why don’t they make limited releases of such wines? These wines would likely sell at a premium, albeit to very small market. But surely that is a more constructive approach than writing “The current fad of higher and higher alcohol wines should stop.” If the Australian wine community can approach this topic in a constructive manner then its about time that the US does the same.

The Acid in My Alcohol

Or is it the alcohol in my acid, or the pH of my…. Oh hell, it’s just wine!

I think most folks know that I’m not a fan of the anti-high alcohol league. I’m not completely sure why but for some reason the league stirs in me images of The League of Gentlemen. No, not The League of Extraordinary Gentlemen, The League of Gentlemen. There is something about this cadre of criers of “nothing above 14.5%” that casts a grim shadow over my world. It’s akin to the foreboding behind the 'Welcome to Royston Vasey. You'll Never Leave!' sign. I picture myself being locked into a little corner of the wine world with people that, well, just don’t sound like a lot of fun. But I digress.

Dan Berger is one of the biggest critics of big wines and Big Wine lovers. I give Berger credit; he knows he’s in the minority. Still I’m not so naïve as to believe that all wines with alcohol above 14.5% are great wines, or even representative of their style or variety. However I’m also not convinced that delicacy, harmony, and balance is found only below the magical number of 14.5% alcohol. But this is the thesis of folks like Dan Berger, Darrell Corti, Randy Dunn and others. It's just unfortunate that they don’t test their hypotheses. But I’m always willing to help, if I can! One of Berger’s most recent discussions on high alcohol wines made a point that I thought worthy of follow-up.

“Look at it this way: The bigger the wine, the more alcohol it typically contains. And the more alcohol a wine has, the less acidity it usually has. High-alcohol wines need more, not less, acid and a lower pH to balance the “sweet” taste of the alcohol. But with high-alcohol wines, we almost always get a higher pH, not a lower one.”

It seemed just a little limiting to me, given the complexity that goes to generate balance, that Berger should focus on the relationship between alcohol and acidity. Does he know something the rest of us don’t? One way to find out is to look at the alcohol and acidity in several wines. It’s a little difficult to do this with a large number of wines simply because alcohol, pH and total acidity (TA) numbers are hard to find for most wines. But I was able to get some data on three wines: Penfolds Grange (Shiraz) from 1955 to 2002; Penfolds St Henri Shiraz from 1993 to 2003; and Carlisle Dry Creek Zinfandel from 1998 to 2005. Grange and St Henri have yet to pass 14.5% alcohol, while the Carlisle Zinfandel has not been below 15.4%.

Graphing alcohol and TA reveals significant positive correlation for both Grange and the Carlisle. St Henri shows a non-significant correlation, although higher alcohol tends to indicate lower TA values. Graphing alcohol and pH reveals a significant negative correlation for Grange; that is the higher the alcohol the more acidity (lower pH), a positive correlation for St Henri (alcohol and pH values both increase) and no significant correlation for the Carlisle although the acidity tends to increase with increasing alcohol.

So if Dan Berger is correct then poor old St Henri, my favorite wine and one of Australia’s most refined, harmonious and balanced Shiraz wines does not fit his thesis. Or could it be that balance (delicacy and harmony) in a wine is just a little more complex than pH and alcohol?
