Beyond Oak

Oak has played a major role in winemaking forever.  C’mon, it’s synonymous with wine. Descriptions of most fine wines list the varieties of oak used in creating the unique effects of each release.  Oak barrels range from high impact, thirsty “new” to “neutral,” which

serves as storage only.  They range ethnically from French, American to Slovenian and for centuries, most winemakers employed “coopers” to construct their own barrels.

In France, renown oak barrel makers are in high demand and like most vintner’s, their craft dates back generations.  Their barrels are the most expensive in the world although their life span triples those from other countries.

California winemakers have introduced oak to chardonnay, a match made in heaven for those rich, creamy wines, something the French would scoff at, adhering to their stainless steel traditions.

I’ve recently noticed that for reasons of both cost and taste, winemakers are moving away from oak in subtle and not so subtle ways. For instance, a few years ago, I tasted a 2012 Foresight Winery “Unoaked” Pinot Noir, my first and later met with Melville Winery whose winemaker, Gary Brewer, employs only neutral oak with all his pinot noir, quite a departure

Many California wineries who produce chardonnay now include at least one “unoaked” release. From the 2012 Columbia Crest Unoaked Chardonnay in Washington State to the 2014 Melville Chardonnay “Inox” in Santa Barbara County, the 2014 Morgan “Metallica” in Monterey and, my personal favorite 2013 Williams Selyem Unoaked Chardonnay from Sonoma, we have begun to lean on stainless steel and other methods.

Great French chardonnay from Burgundy is all stainless steel, oak would be cheating their values. California chardonnay is

identified by oak, though an increase in unoaked releases must be a response to demand.  So, what is the difference between the two?  It basically revolves around mouthfeel and taste.

Oak adds additional aromas to the wine, such as vanilla and hazelnut and tends to build a more rich and creamy texture while stainless steel captures only the aromas and taste originated by the grape, trending toward a more crisp and fruity wine.  Stainless steel chards are generally preferred when pairing with foods such as shellfish, ceviche, tuna and oysters and those oak-laden are terrific al fresco. While these fermentation methods offer clear alternatives, some winemakers are experimenting with even newer ones.

Within the last two weeks, I have discovered numerous vintners fermenting wines in

large concrete “eggs,” rounded vats about six feet tall.  Surely, they seem indestructible with almost an infinite shelf life, but how do they impact the juice. Apparently, the concrete is porous, allowing oxygen into the wine. Concrete vats have been used in winemaking for over century, but the egg shape is a 21st Century concept, first commissioned by a French winemaker in 2001.  The rounded “egg” is more efficient, eliminating dark corners and allowing the juice to easily co-mingle.

some comparisons with a flight of three chardonnay, each from a different fermentation process. The crisp 2011 Thomas George Estate Chardonnay, Concrete, with no malo-lactic fermentation, aged nine months sur lie in concrete eggs, has very forward fruit aromas and flavors with a delightful minerality on the finish. Each process create different nuances and the “concrete egg” will appeal to many palates.

William Selyem Winery uses the “egg” for their crisp 2013 Williams Selyem Chenin Blanc San Benito County while Oregon’s Archery Summit Winery produces the 2014 Archery Summit Ab Ovo Pinot Gris, combining juice aged in the “egg,” stainless steel and oak.  Napa Valley’s Quintessa, known for extraordinary Cabernet Sauvignon blends, has also produced the highly touted 2013 Quintessa

History will determine its ultimate fate, but practicality and effect seems to be telling us that the “egg” is here to stay.

Randall Grahm from Santa Cruz’s Bonny Doon Vineyard and Cellars has produced his flagship Rhone blend, “Le Cigare Volant,” since the early 1980s.  A few years ago he surprisingly changed the fermentation vessels from oak to 5-gallon glass carboys, the same ones that fit atop the office water cooler before plastic became the norm.  Over 900 cases of the 2011 Bonny Doon Le Cigare Volant Reserve “en bonbonne,” a blend consisting

of mourvedre, grenache, syrah and cinsault grapes from eight different Monterey County vineyards, were produced, all aged nine months, sur lie in 5-gallon carboys. After much research, I discovered that “en bonbonne” is in fact a French term referring to the use of glass vessels in wine fermentation, although generally larger than Randall’s 5-gallon containers.

The significant impact that Randall recounts is in the texture of the wine.  He describes the texture as “utterly seamless and sleek, and secondarily, their quality of umami, no doubt a function of the glutamate released from the autolysis of yeast cells during the élevage”.  My interpretation of Grahm’s abstract comments is that, seemingly, the glass carboy, which certainly adds no flavors, acts as a decanter, allowing in oxygen to soften or “open” the wine. Of course, sur lie is the process of combining yeast build up with the juice rather than removing it, also resulting in a more textural vino.

As a “DEWN” member, I am among a select few who have tasted the 2011 “en

We are definitely thinking beyond oak and this is a good thing.  To me, it is all about expanding our comfort zones to embrace new ideas which will result in the betterment of all.  These new fermentation methods will soon assimilate and, who knows, may make oak-centric wines better.
