Cayuse: Unique Terroir or Flawed Wine? Lab Analysis Tells All

By Kori ~ November 8th, 2010.

Before we delve into the lab analysis, let me give you some background information in case you are not familiar with Cayuse and the great debate that rages between Cayuse lovers and Cayuse skeptics. Cayuse Vineyards, founded in 1997 by French-born Christophe Baron, is often thought of as a Washington winery. While Cayuse does have a tasting room in downtown Walla Walla (though it is rarely, if ever, open), the Cayuse winery and vineyards are located near Milton-Freewater, Oregon, in an area known as The Rocks. Viticulturally-trained in Champagne and Burgundy, Baron first visited the Walla Walla area in 1993. A few years later he had plans to buy land in Oregon’s Willamette Valley and plant a vineyard when he stumbled upon a field full of softball-sized stones near Walla Walla that reminded him of the cobblestone vineyards of Châteauneuf-du-Pape in France. He changed course, bought the stone-filled farmland, and planted his first vineyard. While he makes a few other wines, Baron’s focus is on Syrah. Cayuse produces about 3,000 cases per year of their vineyard-designated, biodynamically-farmed wines. The wines are sold exclusively through a mailing list, which has a very long waiting list. Cayuse regularly receives high scores and accolades from wine critics. At the same time, though, Cayuse also has many detractors who do not care for their wines.

Cayuse wines have very good fruit, but it’s hard to get through to the fruit when you taste the wines because of all of the “funk”, and that’s where the differences of opinion come into play. Cayuse lovers will say it’s unique terroir, an Oregon Châteauneuf-du-Pape, and if you don’t like the wines, you don’t have a sophisticated palate. On the other hand, Cayuse skeptics say the wines have serious faults and what you are smelling and tasting is the result of those faults. It’s been an ongoing debate for years, but the lovers have tended to prevail because most of the well-known wine critics have been in their corner.

For several years, both John (Dad) and I have been in the Cayuse skeptics’ camp and have been criticized for it. However, I did considerable research on wine faults when I was studying for the Certified Specialist of Wine exam and have tasted wines from all over the world. John has tasted wine for over 40 years. We both have a pretty good idea of what we like in a wine and what we don’t like as well as what’s good and what is not good. We’re not easily fooled by a wine whose proponents call it a product of unique terroir when, in our educated opinion, it is basically a flawed wine. As Lloyd Bentsen famously said to Dan Quayle, who had defended his inexperience as similar to that of John F. Kennedy, in their Vice Presidential debate, “Senator, I served with Jack Kennedy. I knew Jack Kennedy. Jack Kennedy was a friend of mine. Senator, you are no Jack Kennedy.” Well, we know Châteauneuf-du-Pape and, believe me, Cayuse is no Châteauneuf-du-Pape. Nor is it a Côte-Rôtie, Cornas, or Hermitage either.

In recent years, we at Wine Peeps have reviewed as many Washington State wines as anyone; and I have contended all along that the Cayuse wines I’ve tasted all have had faults (which is why we have written about very few), some bottles showing more pronounced sensory defects than others. While other Cayuse critics have suspected brettanomyces might be the culprit, I thought one of the first bottles we tasted showed signs of volatile acidity, and another bottle showed signs of one of the volatile sulfur compounds like mercaptans. John had taken Amy Mumma’s Wine Faults short course in the CWU World Wine Program and thought I was correct, but how would we ever know for sure?

We love Washington wines and believe they are some of the best in the world. The Walla Walla Valley AVA and especially The Rocks area south of the Washington/Oregon state line have prospered in no small part due to the efforts of Christophe Baron at Cayuse. However, it has always been curious to me that other wines produced from grapes in The Rocks, some literally within a stone’s throw, do not taste at all like Cayuse. Those wines made me suspect that the differences are not terroir but rather winemaking. Talking to a number of respected winemakers and vineyard managers who are in a position to know confirmed our suspicions that there might be problems with Cayuse wines.

Recently, Paul Gregutt, author of Washington Wines and Wineries and a contributing editor for Wine Enthusiast magazine reviewing Pacific Northwest wines, posted on his blog about his review of the 2007 Cayuse wines, and waxed eloquently as usual about Christophe, his unique terroir, and his wines, painting them as an “outrider”, with the implication once again that it takes a special palate to appreciate this special wine.

“When a Cayuse wine is placed in the midst of a blind tasting it will often show poorly. I have seen this happen in a group of extremely knowledgeable wine professionals. Plop any of the Cayuse syrahs into a syrah tasting and see what happens. Odds are, unless someone in the group spots them (either by bottle size or scent) as what they are, they will not be applauded.” –Paul Gregutt on

John commented, interpreting that as meaning:

“If you don’t know it’s Cayuse, you probably won’t like it. But if you do know it’s Cayuse, you know you are supposed to like it.”

Naturally, Paul disagreed.

In another comment to Paul’s post, a reader said:

“…there were too many flaws for me to recognize any terroir.”

Paul responded:

“I see terroir rather than flaws. I suppose a lab analysis would be the most scientific way to resolve that debate.”

Voila! What a great idea, Paul. So we set up an account at the renowned ETS Laboratories in St. Helena, California, one of the most advanced wine analysis labs in the world and ordered samples kits and labels in case we needed them. Then we looked in our cellars and found a 2004 Cayuse Cailloux Vineyard Syrah and a 2005 Chateau de Beaucastel Châteauneuf-du-Pape to put in our private tastings lineup.

As regular Wine Peeps readers know, usually several times a week, the Wine Peeps team gets together for dinner and we have a private tasting with two wines blind. The setup for these dinners is slightly different from our monthly tasting dinners. Periodically, we sack up pairs of wines we have acquired that we would like to blind taste against each other. We label the pairs with a letter (A, B, C, etc.) to keep them together and also indicate on the sacks if they are red or white wines. After sacking up anywhere from six to ten pairs, we put them away. By the time we pull them out of the cabinet for one of our family dinners, we have usually forgotten what the wines are. Depending on the meal that is being prepared, we grab either a red or white pair. These tastings are considered double-blind.

On Monday evening, October 25th, the two wines that we tasted with dinner turned out to be the 2004 Cayuse Cailloux Vineyard Syrah and 2005 Chateau de Beaucastel Châteauneuf-du-Pape. It did not take long for all four of us to suspect that Wine #2 was a Cayuse wine. Paul Gregutt is correct, it is an “outrider” but not in a good way for us. The wine had aromas of pickle brine, almost to the point of being vinegary, as well as olives, cooked cabbage, and burnt matches. On the palate, it was hard to get to the fruit because of the flavors of canned corn, rotten vegetables, and decomposed greens. With our steak dinner, the wine seemed very bitter and even had a formaldehyde taste. We all agreed that we thought it was flawed and that we should submit the wine to ETS for analysis. By the way, we greatly preferred Wine #1 (which turned out to be the Beaucastel) to Wine #2 (which was the Cayuse as we suspected). The Beaucastel was an excellent wine.

After dinner, we poured the remaining wine into the lab bottles and labeled the samples for submission to ETS. We requested three tests on the Cayuse, a standard chemistry panel, a sulfides panel, and an ethylphenols panel. [Note: The samples sent to ETS are identified with a sample number so ETS did not, and still does not (unless they read this post) know the identity of the wine they tested.]

Within two days, we had the results, posted online and emailed to us. Then we had a follow-up call with a representative at ETS to discuss the results. The evidence was clear. The Cayuse was a flawed wine. It had volatile acidity slightly above the normal sensory threshold but at a level a massive Syrah can support, but the worst result from the chemistry panel was that it had a high pH level, which made it more susceptible to bacterial attack. The most damning result, however, came from the sulfides panel. Published literature and ETS studies say that low levels of dimethyl sulfide can contribute roundness, fruitiness, or complexity; however, at levels greater than 50 ug/L, it may contribute vegetative, cooked cabbage, or sulfide smells to wines. According to the ETS representative, this wine had the highest dimethyl sulfide level he had ever seen (312 ug/L), more than 10 times the normal sensory threshold (17-25 ug/L), which accounts for the canned corn, rotten vegetables, and decomposed greens flavors. And, those dimethyl sulfide levels and resulting unpleasant sensory characteristics will only increase with wine age, according to ETS. A layman’s analogy for the effects of dimethyl sulfide in wine would be like salt in food. If you add a little salt to your food while you are cooking, it enhances the flavor, but if you dump in the whole salt shaker, all you will taste is salt.

In case you are wondering what might cause an extremely high dimethyl sulfide level, ETS lists “Possible Causes of Sulfide Problems in Wine” in their Volatile Sulfide Analysis Technical Bulletin:

  • residues from vineyard spray programs
  • high turbidity
  • yeast strains
  • must nitrogen deficiencies
  • other nutritional deficiencies
  • high fermentation temperatures
  • fermentor size and shape
  • inadequate aeration during fermentation
  • gross lees contact and extended lees contact

In the interest of fairness and full disclosure, I must mention that we have only lab tested this one bottle of Cayuse; however, it had the same unmistakable aromas and flavors as every other bottle of Cayuse wine that we’ve tasted through the years. Lab tests like we had performed at ETS Labs are very expensive, costing over four times what we actually paid for the bottle in the first place, but we believe it was worth it in order to either validate our professional opinion that the wine was flawed [which it did] or to admit that they are technically good, but we just don’t like the flavor profile of Cayuse wines.

The popularity of Christophe Baron and his Cayuse wines has been an invaluable asset to the Washington wine industry and especially to the Walla Walla Valley AVA, even though Cayuse is actually an Oregon winery. Walla Walla Fall Release weekend was built on the back of Cayuse’s Fall Release, though Christophe has now moved his release date to April. I’m sure that the successful promotion of his wines has made many landowners in The Rocks very wealthy. Nothing we’ve learned should diminish the potential of vineyards in the area, as long as good vineyard and winemaking practices are followed.

You may be thinking that panning Cayuse is political suicide in Washington wine circles, and maybe it is. But we believe that the truth is more important than politics, and that’s what we endeavor to provide at Wine Peeps. As many can attest, if you make good, fault-free wine, which many, many wineries do here in Washington, we’ll tout you from the rooftops. But if you don’t, we won’t make excuses for you just to stay in line with the popular opinion. Our readers, wine consumers, deserve nothing less.

    I suggest caution when drawing scientific conclusions based on an N of 1, particularly for such a ‘volatile’ topic.

    You two! Sean/Kori need to take your copied quotes and asterisks off line. We are having fun here! Boring to read you did/didn’t mean things.

    May I point out that the “data” is not in fact one point: the data, as I see it, is all the bottles of Cayuse the WinePeeps have tasted that shared the particular flavor profile. All the lab test did was ground their perception in chemistry, allow them to give a name to what they were sensing.

    You may quibble with the accuracy of the (nasal) equipment used, or the conclusions drawn, but the methodology isn’t entirely unsound. Not grant-fundable, of course, but not hopelessly structurally flawed as many here would apparently have it.

    What exactly are the exam requirements to achieve CSW status? Please don’t tell me it’s as easy as reading a 200 page booklet and taking a 100 question mp test…if that were the case the three little letters wouldn’t mean all that much to me. Just saying…

  5. Terry | November 9th, 2010 at 12:43 pm

    Is it time to move the discussion toward winemakers looking to make wine free from restrictions? The lab restricts the freedom and possible range of the art. I get sick when the article above says “the evidence is in” and assumes reasonable folks must agree. Not an objective approach to the piece.

  6. Terry | November 9th, 2010 at 12:49 pm

    actually, it says “The evidence was clear” which sounds even worse now. Wow, throwing creative people under the bus who want nothing more than to be free from restrictions like lab-based analysis is a sad way of saying one does not like something. Am I missing something as I learn more and more about wine and appreciate the differences in a winemakers approach? Or is that too objective?

  7. Catie | November 9th, 2010 at 12:55 pm

    I wish it were as simple as the fact that Kori doesn’t care for Cayuse wines and Sean does. It went beyond opinions when the Cayuse wine was purposely sent to ETS. I think that now, in fairness to Cayuse, when there is a wine the Wine Peeps do not “care for” they need to back it up with an analysis from ETS, or otherwise Cayuse is going to be looked upon as being singled out.

  8. Terry | November 9th, 2010 at 1:13 pm

    Catie – Indeed, there seems to be a ‘I new they suck’ approach to justify something. Sad the article could have reported how the mission of Cayuse is to do things without restrictions, good or bad, and then only to find room for the most restrictive lab based analysis. huh?

  9. Rand Sealey | November 9th, 2010 at 1:19 pm

    From the many comments that were made, Kori’s post sure stirred up a lot of controversy. I have had few opportunities to taste Cayuse’s wines, so I have no opinion on them. It has always been my policy not to review wines that are sold only through winery customer lists. I also only include recommended wines in my Review of Washington Wines. If a wine is flawed or does not offer a reasonable quality-price ratio, I just don’t write about it.

    I have great respect for Kori Voorhees, Paul Gregutt, Sean Sullivan and Catie Walker as wine reviewer colleagues. But I get the feeling that this controversy over Cayuse is getting a bit too personal. Wine is just wine, and all depends on personal preferences, so what’s the big fuss? Why don’t we all just kiss and make up?

  10. Kori | November 9th, 2010 at 1:30 pm

    Thank you, Rand. I think this is a good time to shut down the comments. Thank you all for participating in the discussion. Cheers!
