The eternally popular grape beverage—259 million cases of wine are inbibed on average each year—and the human race have much in common in their diversity: different shades of color, age, nationality, body type, and personality.[1] Increasingly, the vino of your choice—whether it's a young and lively Pinot Gris from Oregon or an aged, complex French Burgundy—are available in eco-friendly varieties.

Often lumped under the banner of "natural wines," it can be bewildering to decide which "green grape" provides the most eco-friendly variety. The quick answer: before you uncork, sniff, and swirl, look for local first and organic or biodynamic if available. While the chemical pesticides and fertilizers associated with the growing of conventional grapes take a significant eco-toll, the largest negative environmental impact associated with this libation is actually incurred during fuel-intensive and polluting transport.

Transport and climate change

Drinking wine produced close to home supports regional agricultural efforts and eliminates the carbon footprint that results from the long trek a bottle may make from vineyard to your grape-loving palate. It is estimated that some bottles of premium vino consume three times their weight in petroleum. It's also been concluded that issues of transport—specifically how the wine was transported—have a greater negative impact on climate change than issues of organic versus non-organic viticulture. For Americans living points west of an imaginary "green line" that runs through Ohio, it's more carbon-friendly to drink wines trucked in from Oregon, Washington, or California. For those living east of the green line, it's thought to be less eco-damaging to imbibe European wines since the wine has traveled via container ship (the most carbon-efficient mode of transport) and then trucked a shorter distance. It's also recommended that grape-guzzlers seek out libations bottled in magnums rather than picking up several normal-sized bottles or half-bottles since the glass to wine ratio of a magnum is less.

Organic wine vs. biodynamic wine

Two key words on the discerning tongues of those concerned with making the farming of grapes for wine more eco-friendly: organic and biodynamic. Although the wine-producing grapes grown under organic and biodynamic standards are similar, there are some distinctions to keep in mind.

Organic wine

Although not an incredibly pleasant fact to digest while unwinding with your preferred fermented digestif, wine-producing grapes are subject to 17 different fumigants, pesticides, and herbicides. In California—by far the most prolific producer of US wines—grapes are treated by more chemicals than any other conventional crop: a whopping 59 million pounds of toxic chemicals in 1995 alone.[2]

In accordance with standards established by the National Organic Program, wines can claim four varying degrees of "organic-ness" on their labels:

• 100% Organic: The wine must be made from 100 percent organically grown grapes and may not have any added sulfites. The wine may have natural sulfites but the level cannot be more than 100 parts per million. Additionally, the labeling must provide information about the USDA-regulated certifying agency as well as an ingredient statement.
• Organic: Guidelines for "Organic" are essentially the same as "100% Organic." However, 5 percent of ingredients can be from a conventional agricultural ingredient that is not organically available; the remaining 95 percent must be organic.
• Made with Organic Ingredients, Made with Organic Grapes, or Organically Grown: To make any of these claims, a wine must be made from at least 70 percent organic ingredients that are identified on the labeling; the remaining 30 percent of ingredients must be conventional agricultural products that are not organically available. Additionally, the labeling must provide information about the USDA-regulated certifying agency but cannot display the official USDA Organic seal. These wines may contain added sulfites along with naturally occurring ones but the total number cannot be more than 100 parts per million.
• Some Organic Ingredients: These wines contain less than 70 percent organic ingredients, cannot display the USDA Organic seal, or refer to organic ingredients or certifying agencies on the labeling.[3]

Biodynamic wine

Although the marriage of pesticide-free farming and astrology may strike some wine-o-philes as arcane (filling cow horns with dung and burying them in vineyards is a recommended practice), those who practice biodymanic—short for "biologically dynamic"—viticulture (and those who imbibe its fermented fruits) praise biodynamic wines to be "beyond organic." Based on the writings of Austrian philosopher Rudolf Steiner, biodynamic agriculture predates organic practices by about 20 years. Steiner believed chemical pesticides and fertilizers to be not only detrimental to the quality of crops but also a sign of a spiritually absent farmer who failed to align him or herself with the cosmos. In its essence, biodynamic viticulture is all about ecological harmony between the grapes, the farmer, and other organisms within the ecosystem.

Biodynamic wines are not certified by the USDA but by independent biodynamic agencies. Demeter International (headquartered in Brussels) is the global biodynamic certifier with a US branch based in Oregon. Biovin is a certifying agency operating strictly in France.

Waste

According to reports published by the US Environmental Protection Agency (EPA) in 2005, 10.9 million tons of glass containers (including beer, wine, juice, soda bottles, and other products) were disposed of in the United States; just 2.8 million tons were recovered for recycling.[4] It takes a glass bottle about 1 million years to break down in a landfill.[5] Making your won wine can easily solve this problem: although bottling plays a part in home winemaking, it takes place on a much smaller scale, and bottles can be reused. Or, be sure to recycle your wine bottles.

Controversies

The move toward organic farming has received a fair amount of criticism. Norman Borlaug, a Nobel Peace Prize winner, believes organic farming techniques to be detrimental to the environment. In a December 2006 issue of The Economist he cites that the low yields of organic farming call for the destruction of more land while the use of the synthetic fertilizers allows farmers to harvest vast amounts of, for example, grapes, in a small area of cultivated land. Borlaug received the Nobel Peace Prize for his work on high-input crops that have increased world food supply, but has been criticized because of the resultant increase in reliance on monoculture cropping and inorganic fertilizer use.

Related health issues

Wine, when not consumed in moderation, poses several health risks including alcoholism, cirrhosis of the liver, and various cancers. However, sensible drinking—the American Cancer Society defines this as no more than one drink per day for women and two per day for men—of wine, beer, and other alcoholic beverages can be beneficial, as it has been found to decrease the fatal effects of heart disease, lowering the likelihood of death by 30 to 40 percent in comparison to nondrinkers.[6]

There are other health perks attached to wine drinking, particularly red wine. It contains beneficial vitamins, minerals, natural sugars, and potassium. Wine also aids in digestion, provides relief to those with sleeping problems, and may help curb dementia and Alzheimer's disease.

Sulfites

Can't shake that pounding "wine headache?" You may be suffering from a sulfite allergy, a sensitivity to a naturally occurring compound in grapes, onions, apricots, garlic, and other plants. Therefore, wines labeled "sulfite-free" are not truly free of them although they may not have added sulfites. Adding sulfites is commonly practiced by winemakers to preserve and protect wine—your bottle of Merlot would turn to vinegar in a few months without them—but those who want to enjoy a glass sans throbbing temples should reach for "young," organic wines free of added sulfites.[7] The US Food and Drug Administration (FDA) estimates that one in every 100 people has a sensitivity to sulfites.[8]
