The Science of Wine: from Vine to Glass, 2nd Edition, by Jamie Goode

Science is a scary word to those of us who know little about it.  There were two ways to learn a concept, according to the U.S. Air Force:  Go to a technical school, or “On the Job Training.”  As a wine writer, I applied the OJT method to learn what little I know about science, more specifically, the science of wine. 

So, it was with a combination of approach (wine) and avoidance (science) that I began reading Jaime Goode’s revised, “The Science of Wine.”  It didn’t take long, though, before I was deeply involved and learning something new.  Yes, old dogs and new tricks and all that….  But this is not a wine book as much as it is a text about science as applied to grape growing, winemaking and wine tasting. 

Goode is a Brit who was writing about science until he got side-tracked and took up wine writing.  His carry-over use of scientific jargon and lengthy scientific explanations throughout “The Science of Wine” may be off-putting to some readers, but hang in there, the annoyances are offset by the thoroughness and depth of this book. 

As you dive deeper into “Science,” it becomes clear that there is something for just about every wine drinker, aided by an extensive Glossary.  In Section 1, “In the Vineyard,” the author breaks down the science of soils and grapes into nine chapters, including The Biology of the Grapevine, Precision Viticulture and such hot-button topics as Biodynamics and Phylloxera.  Goode also explains lutte raisonee, a new French viticultural approach, which means “the reasoned struggle.”  According to Goode, lutte raisonee is a third form of vineyard management between biodynamics and the more conventional “chemical-based” agriculture.  Lutte raisonee is based on the more familiar approach, at least in this country, known as Integrated Pest Management.

In Section 2, Goode moves the science from the vineyard to “In the Winery,” addressing such topics as Oxygen Management, Sulfur Dioxide, Brettanomyces--all possible sleep-inducing subjects, unless you are a winemaker or hoping to become one.  Brettanomyces, or “brett,” was THE popular buzz word a few years ago.  Goode devotes eight pages to the wine fault, calling it fascinating, “partly because it (brett) is one of those ‘faults’ that in some contexts can be regarded as positive.”  The good-fault / bad-fault brett paradigm is more familiarly associated with Pinot Noir, as in “A little brett adds complexity to the wine.”  But Goode cites a case study focusing on the flavor profile of Chateau de Beaucastel, the noted Chateauneuf-du-Pape wine with a higher than average Mourvedre content.  The question, posed by Goode and others:  Is Beaucastel infected by excessive brett, is it the terroir, or could it be the high percentage of Mourvedre?

Goode’s take on “Sulfur Dioxide,” a subject he devotes five pages to in Chapter 14, is that, with the exception of winemakers, other wine-interested folks (including writers and consumers), don’t have a clue.  “I suspect that most don’t have a clear understanding of the issues involved (with sulfur dioxide).”  He then provides a concise primer on such related subjects as free and bound forms of sulfur dioxide and the importance of pH, a term I’ve had explained to me a couple of dozen times but still don’t understand.  “For the benefit of those who have long forgotten their school lessons [if you even had them], pH is a measure of how acidic or alkaline a solution is.”  Right.

Readers who think of themselves as being more interested in how a wine smells and tastes than in wine chemistry will find Section 3, “Our Interaction with Wine,” the most satisfying part of this book.  Central to Goode’s theme is a long section on “Taste and Smell” that examines the anatomy of non-tasters, medium tasters and super-tasters.  Goode cites numerous studies on the subject, including one by U.S. Master of Wine Tim Hanni that addresses the individual the differences in taste perception while delving into the controversy in science circles swirling around hyper-tasters and non-tasters.  For the curious, Goode provides a simple test to determine if you are a super-taster. 

Closing out this chapter, which may require some people (like me) to re-read it a few times, Goode offers a short sidebar on “smell blindness” or anosmia.  The example he uses is the surprising fact that one-fifth of people tested cannot detect rotundone, a wine flavor compound that is responsible for the “black pepper” aroma in some red wines such as Syrah/Shiraz.  Another of Goode’s intriguing sidebars is “The Pepsi Challenge,” an update, with a wine connection, to the famous blind test pitting Pepsi against Coke that caught the public’s interest in the 1970s and early 1980S.  

Chapters 20-24 explain more scientific/sensory “perceptual events,” as Goode labels them.  Included are “Wine and the Brain,” “Saliva, tannin and mouth feel,” “Synesthesia, language and wine” (the stimulation of one sense by another; think of the interaction of smell and taste), “Wine flavor chemistry” and “Wine and Health.”  Due to the limits of space, I’ve skipped over these chapters, but I recommend a thorough read with a glass of wine in hand; however, unless your geek level is very high, take these five chapters one at a time.

Having the ability and skill to be able to boil down technical and scientific concepts to everyday language is rare among science (and wine) writers.  Goode doesn’t hit the mark all the time in “The Science of Wine,” but he does have a knack for blending science with common sense that makes for entertaining reading.

Far Niente, Oakville (Napa Valley, California) Cabernet Sauvignon 2012 ($145)
Over the years the Far Niente Cabernet has evolved into a bigger, bolder version of the earliest vintages. The 2012 is robust and layered, exhibiting richness on the palate, exceptional depth and weight, and succulent black-fruited aromas that linger through an extraordinarily long finish. This is a classic Far Niete Cab, one of the finest in a long line of stellar vintages from one of the Napa Valley's most distinguished producers. It could certainly benefit from additional time in the cellar, but won't disappoint if opened tonight. 97 Robert Whitley

Things I Think I Would Like to Drink
Robert Whitley

Truth be told, there are but a handful of spots in the world where sparkling wines made in the methode champenoise tradition, with the second fermentation in the bottle, are the rule rather than the exception. Most bubbly is made using the bulk Charmat process, which produces perfectly fine sparkling wine but generally without the structure and complexity of bubbly made using the traditional Champagne method. America is one of those places you can count on for excellent sparkling wine made using the Champagne technique, but even here that process is restricted to a few regions and a handful of dedicated producers. Domestic sparkling wine will never quite replicate Champagne in taste or mouthfeel, owing I believe to the unique combination of climate and chalky soils found in France's Champagne region.
Estate Wines: What are They, and Are They Worth the Price?
Michael Apstein

The word 'Estate' on a bottle of wine lends prestige and often entails a bigger price tag. But what does the term really mean…and is this designation actually worth the price premium? The Alcohol, Tobacco, Tax and Trade Bureau (a.k.a. TTB) regulates wine in the US. According to their rules as detailed in the Electronic Code of Federal Regulations (eCFR) (Title 27, Chapter 1, Subchapter A; Part 4.26) a winery can label a wine as 'Estate' if: 1) the winery grew all the grapes on land it owns or controls with at least a 3-year lease; 2) the entire wine making process took place at the winery, and 3) the winery and the vineyards are in the same AVA (American Viticultural Area). An estate wine should not be confused with a 'single vineyard' wine, which may or may not also be an estate wine, depending on whether it conforms to the TTB regulations.

WINE WITH…Asian Beef Salad

Among the most delicious and versatile gifts of global gastronomy are riffs on traditional Asian salads of greens topped with slices of grilled or pan-seared steak. The Vietnamese version generally calls for Nuoc Cham, a classic dipping sauce that doubles as the salad dressing. Diners enjoying Korean Bulgogi roll the beef up in lettuce leaves. Spicy, tangy Thai beef salad (Yum Neua) may have a little more hot pepper heat than the others, but all the variations on this Asian theme are savory and refreshing as well as being fairly quick and easy to prepare. Here is our hybrid version.

Chile's Original 'Garage Wine'
Mary Ewing-Mulligan

Alvaro Espinosa is Chile's leading advocate for organic and biodynamic grape farming. He was also Chile's earliest proponent of Carmenere, when in the mid 1990s scientists identified as Carmenere vines in Chilean vineyards that were thought to be Merlot; at the time he was winemaker at Carmen. In 1996, Espinosa created Antiyal--which has been called Chile's first 'garage wine'--as a small family venture, producing tiny quantities of the namesake wine. In 2012, he produced only 400 cases of Antiyal. The 2012 vintage of Antiyal is particularly attractive -- a rich red wine with exceptional balance, seductive texture and a complex but not overpowering expression of aromas and flavors.
