Every once in awhile, I get a client who wants to purchase a wine for medicinal or health purposes. “I need something to help me get a good night’s sleep,” says one. “I want to drink wine because it is healthier than the Scotch and bourbon I normally drink,” says another. “Can you help me find something that will turn off my thoughts so I can chill out after work?” asks yet another. Almost always, the person requesting help adopts a serious tone, one that might be used when asking for a remedy from a medical doctor. At this point, I visualize myself wearing scrubs, a stethoscope, a lab coat, and comfortable shoes. Recalling my theater days from college, I go deep, utilizing the Stanislavski method of acting. I mirror the client’s serious demeanor. This a delicate situation because, while I want to deliver on the clients’ requests, I also feel the compelling need to inform them about wine’s role in relation to health and specifically the malady they hope to cure. As Doctor Wine, I simply cannot, in all good consciousness, simply recommend a bottle or two and send my clients on their way. To do anything less than compassionately explain how wine will affect my patients, I mean clients, and what they can expect, is a travesty to my commitment to the Hippocratic oath. Please, on the cellar stage, I am an artist. Wine and alcohol in general have been appreciated for their medicinal properties since ancient times to cure everything from the plague to the common cold to poisoning and mental disease. Basically, any ailment you can imagine has been addressed by physicians, including Hippocrates, with a wine remedy. Records exist on such medical treatments in ancient Egypt, Mesopotamia, China and most civilizations. The Romans and Greeks in particular have a long history of appreciating the curative value of wine. Pliny the Elder was a leader in scientific and medical theories until the middle ages. He believed wholeheartedly in wine as medicine and became known for his quotes, “In vino sanitas” (in wine there is health) and, “In vino veritas” (in wine there is truth). While anything in excess can be detrimental to your health, I am not alone in valuing the magic that happens when you uncork a bottle of wine in good company. Wine, like tea and coffee, encourages us to slow down and have a good conversation with family and friends, something I find satisfying if not therapeutic. Civilizations intent on treatment not only drank wine but also applied it to their wounds. They were on the right track, because wine is antiseptic and antimicrobial, contributing to the healing of wounds. Alcohol is a disinfectant, and the tannins in wine, along with other compounds, actually form an environment that is conducive to healing physical injuries. It is common knowledge that alcohol has been used throughout history as a safe alternative to polluted and infected water. The father of pasteurization, Louis Pasteur, felt that wine was “the most healthful and hygienic of beverages.” Sometimes civilizations added herbs or bitters to wine as they built impressive drinks to combat what ailed them, a tradition that continues to this day in the form of digestifs such as sweet vermouth, an aromatized wine with barks, herbs, spices, flowers and other botanicals. In Medieval Europe, monks provided health care to their communities. Many orders had their own proprietary recipes for wine-based medicine. In the twentieth century, what is known as the “French paradox” came into vogue, when an article by Professor Serge Renaud revealed that the French, a culture notorious for producing and drinking wine, had a lower rate of coronary heart disease than Americans despite consuming a diet high in fat. While no research has proven that wine is responsible for the French paradox, science is demonstrating that the tannins, antioxidants and flavonoids in wine can contribute to good health, assuming the proper moderation. These nutrients can also be found in berries and grapes in their raw, unprocessed state. As a wine lover, I’m going for the fermented version when dinner hour rolls around. For the client telling me, “I need a wine that will help me sleep,” we scan the wineshop aisles for candidate bottles while I explain, like a little bird on the shoulder, that drinking wine will, in fact, be at odds with the goal of getting a good night’s sleep. As we consider this bottle or that one, we discuss which wines might work for the nocturnal need that is being addressed. The client pretty much ignores the facts that I am sharing as to what will actually happen when consuming wine before bed. Yes, the wine may cause my client to fall asleep sooner than usual, but wine, in any appreciable quantity, needs to be processed by the body before a good night’s sleep is possible. The client will find himself waking up during the night needing to relieve himself. Feeling parched, he will reach for a glass of water because alcohol is a diuretic. Alcohol dehydrates you by removing fluids from your blood via your renal system, including your bladder. Dehydration is a key cause of headaches and general malaise experienced by wine drinkers the morning after a party. It will take about one hour per unit of alcohol to exit the drinker’s system (a unit is about one small glass of wine). Then, and only then, will my client experience a blissful state of sleep. After this back-and-forth exchange, the client and I come to a consensus on a couple of bottles to “solve” the sleeping problem and everybody is happy. The client has his elixirs and I have sold wine while providing pertinent information not only about the attributes of the wine but also on the science associated with drinking so my client can make an educated decision. By the way, clients always buy the wine, though they may modify their choices based on what I explain as to the workings of wine and the body. For the client who wants to switch from spirits to wine for the purpose of lowering consumption of alcohol by volume, I look for similar attributes between the beverages. If the client likes brown spirits such as Scotch whiskey or bourbon, I might suggest Oloroso, a full-flavored, full-bodied fortified Sherry that sports a dark color and has a dry finish with an ABV of about twenty percent. Thinking about something chewy and substantial like Scotch, I might also offer full-bodied wines with ample tannins such as Touriga Nacional, Cabernet Sauvignon or Syrah, all with ABVs of around fourteen or fifteen percent. While those ABVs are considered high in the world of wine, they are well below the minimum forty percent or so found in Scotch or bourbon. If the client wants a white wine, I direct them to oak-aged, full-bodied whites in varieties like Grenache Blanc, Chardonnay and Marsanne. On the other hand, if the client drinks clear spirits such as Vodka, we look at white wines such as a lean and dry Chenin Blanc, Albariño or Verdicchio. Like Vodka, these wines are usually light-bodied, light in color, and crisp. If the client enjoys a flavored Vodka or Aquavit, I might suggest a grassy Sauvignon Blanc or a dry Vermouth. Crisp rosés would also work for Vodka drinkers, as might light-bodied reds like Frappato, Zinfandel and Pinot Noir. Clients always buy the wine, though they may modify their choices based on what I explain as to the workings of wine and the body. For the client who wants to calm her thoughts and unwind after work, which is most of us, we discuss the types of wines and other beverages she enjoys. I tailor my suggestions according to her taste profile. Since I see myself in a lab coat, I might throw in additional suggestions like meditation, massage, and more time socializing with friends and family to promote stress relief and relaxation. If I spot the opportunity, I recommend drinking slowly and accompanying the wine with plenty of water and a delicious meal to combat dehydration, inebriation and sleeplessness. For the purpose of this list, we are calling out the extremes of high alcohol and low alcohol varieties, not medium alcohol varieties. What is considered high alcohol? Fourteen percent or higher alcohol by volume is high. Medium alcohol is eleven to thirteen point nine percent. Low alcohol is anything below eleven percent. The varieties listed below do not necessarily adhere strictly to these numbers but are generally considered to fit neatly within the categories. The grapes listed as high alcohol are naturally higher in sugar than other grape varieties. During the wine-making process, sugar is converted primarily into alcohol, carbon dioxide and glycerol. Grapes with a low sugar content appear on the low-alcohol list. In the vineyard, climate affects the level of alcohol. Hot-climate wine regions encourage the ripening of the grapes, thus driving up the sugar levels and, through fermentation, the alcohol. In moderate climates, grapes enjoy longer hang time on the vine, building up sugars and flavor. In cool climates, grapes struggle to ripen and, regardless of variety, will have less sugar. A bottle of Chardonnay from California’s warm Napa Valley will generally have a higher alcohol level than a cool-climate bottle from Chablis, France. If a grape is high in sugar, it does not necessarily mean the wine will be sweet. If the yeast consume and convert the sugars to alcohol, the finished wine is dry. However, high alcohol wines give us the perception of sweetness on the palate and are more full-bodied than low-alcohol wines. If the alcohol level is too high, which can happen easily in warm vintages and especially in warm regions, the winemaker has several options to lower the ABV such as adding water or blending with lower-alcohol wine. Driving the level of alcohol starts not only with grape selection but in the vineyard. To avoid an overly alcoholic wine, the vintner may ask the vineyard manager to harvest the grapes early, before they get too ripe and full of sugar. The downside of early picking is that flavor compounds and tannins may not get the chance to fully develop. Many decisions come into play, from the vineyard to the cellar to aging, bottling and storage when it comes to making a high-quality, well-balanced wine. In cool climates where ripening is a challenge, vintners may add sugar before or during fermentation. The sugar does not sweeten the wine. The intent is to provide additional “food” for the yeast to process. The goals: higher alcohol, mouthfeel enhancement, and a balancing out of the wine’s acidity. Adding sugar, known as chaptalization, is highly controversial and illegal in several warm wine regions such as California, Italy, Argentina and South Africa. The practice is allowed in some cool regions in Germany, Austria, France, and Oregon, to name a few. The practice is essential for producing the base wines of Champagne, where the grapes must be harvested with pronounced acidity. Later in the process, Champagne producers may add a sugar-wine solution just prior to corking, a practice known as dosage, which may add sweetness to the finished wine. Chaptalization is regulated in one way or another in many wine regions. Incidentally, producers around the world are usually taxed according to the wine’s alcohol level. The higher the range of alcohol, the more taxes they are usually asked to pay by taxing authorities. The stated alcohol level on the bottle may differ from what is actually in the bottle, often between one and two percent. If the taxing authority tests the wine and finds it to differ significantly from what is stated on the bottle, the producer faces fines or penalties. Let’s talk a bit about how the alcohol level is experienced. On the nose, you do not actually smell alcohol but there are telltale signs that may give you clues as to the level of alcohol. For instance, it is possible to detect alcohol heat on the nose. Also, if the wine smells jammy or like raisins, the wine may have a high level of alcohol. On the mouth, alcohol is tasteless, so again we are looking for clues to help determine the level of alcohol. High alcohol wines may taste of jammy, ripe fruit and have lower acidity. They are more full-bodied with a rich character and perceived sweetness, even though they finish dry. High alcohol wines, once ingested, may give you heat in the throat, mouth, nose and possibly the chest. Low alcohol wines are generally tart and lean, with high acidity and a green or underripe fruit and herbal character.

When my mouth waters for wines with oak characteristics, I might first think of red Bordeaux variety grapes such as Cabernet Sauvignon or Carménère because they are traditionally aged in oak, whether as blends (customary) or single variety offerings (gaining in popularity). In discussing oak aging, we often think of reds first, but whites are also part of the picture. Just yesterday I ordered a R de Rieussec 2017 Bordeaux that is roughly half Sémillon (a grape that fascinates me) and half Sauvignon Blanc (also fascinating, but for different reasons). This wine is produced as a dry white in a sub-region of Sauterns that neighbors Château d’Yquem, a sweet white wine producer in a league of its own. If you you appreciate the effects of oak in wine, you are not alone. Many of the world’s fine wines are aged in casks, giving the wines added complexity, richness, flavor and body. Oak imparts wonderful flavor compounds such as vanilla, spices, caramel, and smokiness. The winemakers of Burgundy are known for pioneering techniques to shape the flavors and richness of Chardonnay, including the use of old barrels, in both fermentation and aging. In addition to barrels, both whites and reds can be aged in stainless steel, concrete, amphoras, and other vessels, depending upon the choices of the winemaker. The R de Rieussec was barrel aged, and I can’t wait to receive the delivery at my doorstep in a few days. Most white wines around the world are fermented in stainless steel tanks, giving the maker control over temperature, oxygen ingress and egress, and other elements of winemaking. Stainless steel tanks are a safe bet for the fermentation of whites. However, some vintners choose to ferment a portion of their white wine in oak barrels, like the making of the wine I just ordered. Twenty percent of the wine is fermented in barrels while the balance is directed to large vats for fermentation. Eventually, the barrel-fermented wine is blended with the batch from the large vats. The winemaker tastes the wine in each barrel to follow its unique characteristics, then decides how much from that barrel will be blended into the whole. This process allows for quite a bit of creativity in the final outcome of the wine. Fermentation in new oak provides expressive flavor and noticeable texture to white wine. If the winemaker ferments in previously used or old, neutral barrels, mostly the texture, rather than the flavor, will be affected. Red wines require hands-on activities during fermentation to break up the cap of pulp and skins that build up on the surface of the wine. Techniques such as “punching down” ensure that this thick matter is redistributed into the wine so that the color, flavors and tannins will be properly extracted. The intervention that red wine requires makes it practical to use large vessels rather than wine barrels for fermentation. When I ferment wine at home, I gently push down on the pulp and skins and stir them into the wine. This stirring helps to cool the wine when fermentation is intense and the temperatures rises. Part of my mothering of the wine is to monitor the temperature at least twice daily, and I keep dry ice on hand to cool the wine if necessary. If the fermentation temperature gets too hot, the health of the yeast is at risk and the warmth may attract undesirable organisms. The result can be wine with stewed fruit flavors and muted aromatics . . . wine that is a disappointing shadow of what it could have been. If the fermentation temperature is too low, the yeast can go dormant and stop working. Nobody likes a stuck fermentation. When that happens, you have to figure out how to wake up the yeast so that fermentation can continue until the wine is dry or deal with an end product that is undeveloped and sweeter than planned. Since sweet wines are not as popular in the market as in the past, most makers do everything possible to nurture the yeast throughout fermentation to ensure a dry finish. During winemaking with grapes, I take sugar readings, taste the wine, examine the skins, seeds, pulp and liquid throughout the fermentation. In this manner, I develop an intimate relationship with the wine, as do many winemakers. Driving the fermentation is my favorite part of homebrewing. Perhaps car lovers feel this love when they take an excursion in a nifty car, especially a stick shift, where you effectively become a part of the machinery that enables the drive. I once incorporated maple syrup with the juice from apples to create what is known as an acer cider. If you have ever tasted the juice of freshly pressed apples, you know that it is very sweet. The maple syrup I added introduced additional sugar to the mix, overwhelming the yeast and the fermentation stalled after a few days. I tried adding more yeast in hopes of restarting the action but it became clear that the yeast could not survive in that environment. There was more sugar there than the yeast could process. Note to self: use less maple syrup the next time. Luckily it was a small test batch. I considered throwing out the acer cider, but then remembered reading about an ancient civilization that fermented wine to about four percent then fortified it with spirits and botanicals. (Fortification is the addition of a distilled spirit, often brandy, to a wine either during or after fermentation.) I decided to give this approach a try since my acer cider had fermented to four percent. The botanicals and alcohol balanced out the sweetness of the cider and stabilized it, and my dinner guests enjoyed it as an after-dinner drink. It is very helpful to continuously learn from others, including ancient civilizations, when it is time for problem-solving. Speaking about oak, my mind also jumps to Spain, where oak aging is central to the production of that country’s signature grape, Tempranillo. I might also think about an obscure but fascinating wine region, such as the Jura in eastern France, where the wine is matured in oak under a veil of yeast to create the exotic vin jaune, one of the world’s most intriguing and rare wines. Vin jaune is a dry wine produced in a manner that is similar to Spain’s Fino Sherry, which is also dry and complex, relying heavily on yeast for protection and development. Vin jaune is produced from Savagnin grapes, while Fino Sherry is made with Palomino Fino grapes. Another difference between the two is that Fino Sherry is a fortified wine while Vin jaune is not. Of course, when it comes to oak aging, there is also Italy to think about. Barolo wines, made from the Nebbiolo grape, need time in oak to calm their tannins and aid in their evolution. Really, it is difficult to name even one winemaking country that does not use oak to mature their wines gracefully. The list below spotlights the grapes that makers might look to first when considering the use of oak. During winemaking with grapes, I take sugar readings, taste the wine, examine the skins, seeds, pulp and liquid throughout the fermentation. In this manner, I develop an intimate relationship with the wine, as do many winemakers. Most grape varieties do well with oak aging, except those that are sensitive to the effects of oxygen. In those cases, the wines will likely be aged in steel or concrete tanks, or the winemaker will blend these delicate wines with other heartier grape varieties before placing them in a barrel. Some varieties have distinctive aromas that the winemaker wants to accentuate, as is common with Grüner Veltliner, Sauvignon Blanc and Riesling. In this case, the goal is to preserve fruit purity with no oak flavors and other influences getting in the way. The decision on whether or not to use oak is driven by the winemaker’s intent and creativity, customs, wine laws, budget, and other factors. French and American oak barrels are often favored by winemakers, though oak can be sourced from many countries. Incidentally, barrels can be made from other types of wood, such as chestnut or acacia, but oak is much more common. France’s tight-grained oak delivers subtle spice, cedar, hazelnut and smoky notes along with silky textures. The comparatively looser-grained American oak is more forthright, boldly contributing vanilla, coconut and cinnamon flavors along with a creamy texture. Older trees tend to have the tightest grains regardless of location. For some regions, the choice of oak has origins in history and politics rather than organoleptic preferences. The Spanish have a long history of disagreements and consequently wars with France. From the sixteenth to the nineteenth century, the Spanish Empire owned some of what is now American land, including Florida, and this access to North America provided a ready resource for sourcing oak without having to deal with the French. To be made into casks, oak needs to be air-dried, seasoned and toasted over fire. The amount of toasting dramatically affects the finished wine’s flavor. The higher the toast, the more oak influence you will find in the wine. New wine barrels release more intense flavors than used barrels. With each use of the barrel, the flavors imparted by the wood become less pronounced in the wine. There is a trend toward a more subtle use of oak as wine drinkers and critics increasingly favor subtlety and nuance in fine wine. Moreover, wines with subtle oak influences are more easily accessible to drinkers and are ready to drink now, in contrast to heavily oaked wines that require time to calm down the intensity. Casks permit the slow ingress of oxygen, smoothing it out and aiding in the wine’s development. Some of the wine is lost to evaporation when it is being aged; this is known as the “angel’s share.” Each cask holds several gallons of wine inside its staves (planks), further concentrating the wine for more pronounced flavors. Small casks come into more contact with wine than large casks and therefore take on oakier character. Oak vessels provide an ideal environment for the the natural chemical conversions that wine undergoes as it matures. Winemakers can add oak chips or staves to wine in lieu of using expensive barrels. These additions will add flavor but will not influence the texture of a wine as would a cask. The use of oak chips or staves or even oak powder is one way that mass producers make low-cost wines available to the public. The amount of time the wine spends in oak also affects the intensity of the wine’s flavors and textures. A fine red wine aged for two years in new oak will have characteristics that are very different from a fine red wine aged for ten years in new oak. As the two-year-old red ages, the tannins will smooth out. Primary fruit flavors will concentrate and evolve from fresh-fruit characteristics to those of dried fruit. Other flavors heretofore hidden by the bold fresh fruit come into their own over time. Tertiary flavors, those of maturation, can include mushroom, tobacco, forest floor and leather in reds. White tertiary flavors might be ginger, honey and cinnamon. The wine’s color will change, with reds losing color while whites grow darker. The spicy notes imparted into the wine from the cask will mellow. Wine evolves throughout its life cycle and the day you open the bottle, you capture the wine at a particular stage of development. That being said, the majority of wines are intended by the producers to be enjoyed upon release to the public.
