You know that guy in your group of friends that always brings wine to the party JUST so he can talk about it? He’s always saying things like “Ooh! There are notes of bacon! Reaaaally swish it around you’ll get those hints of cream soda. Really taste the purple.” It may sound strange, and it may make you get different friends, but all those different smells and tastes come from complex chemistry that gives each bottle of wine its unique flavors. [REACTIONS INTRO] First off, sorry high rollers, but no matter how much you paid for it, a bottle of wine is about 98 percent water and ethanol. It’s the remaining couple percent that makes wine taste like wine, and more specifically makes a shiraz taste different than a pinot noir. It comes down to three things: grapes, soil and climate. If you think all wines are pretty much the same, they ain’t! There are more than 10-thousand wine grape varieties in the world, all producing different tastes and smells when made into wine. Dirt is also a big factor. Famous winegrowing areas like France, California and Chile have distinct minerals in their soils across their vast geographies that make wines different. There are up to 60 trace elements in wine that help identify a soil or grape variety. Researchers can even identify chemical fingerprints in wine that point to the exact trees used to make the wooden barrels many wines are aged in. It’s like wine CSI, but with 100% less Caruso. The other huge factor is climate. Winemakers know that cold climates produce lower alcohol wines with more subtle flavors, while warm regions make more robust wines. That’s because the ripening process that produces sugars and many flavor molecules, slows at cooler temperatures. Once the grapes are crushed, natural and added yeasts begin to eat the sugars, turning them into alcohol and carbon dioxide. The carbon dioxide gas is allowed to bubble out. Like yeast farts. But as yeasts digest sugars and other compounds present in grape juice, they produce a host of molecules that give wines their flavor. Yeasts make acetic acid and other acids that give wines their tartness. Derivatives of pyruvic acid, contribute to red wine’s color. Yeasts also make diacetyl, which give Chardonnays their “buttery” aroma. And then there are the hundreds of other molecules that give wines their very specific flavors. For example, scientists have figured out that methoxypyrazines make some wines taste a bit like bell peppers. And it doesn’t take many molecules to tickle the taste buds. two parts per TRILLION of methoxypyrazines. Different molecules give the flavor or smell of grasses or nuts, while other common wine flavors, like chocolate or even tobacco, haven’t been pinned to a specific molecule. Another big component of wine’s flavor is tannins. Tannins are big molecules that come from the skin and seeds of grapes and also the wood in barrels used to age the wine. Look at that big sucker. Some tannins trigger taste receptors on your tongue and can give wine a bitter taste. Others can make your mouth feel dry, known as “astringency”. Remember gang, taste and smell are very complex processes, both chemically and in how your brain interprets them. So yes, you may not taste bell pepper or chocolate and someone else might. Don’t worry about it. Just enjoy! Thanks to our friends at Azari Vineyards in Petaluma, California for letting us drop by their gorgeous winery and raise a glass. Find out more about them in the description. If you want to keep this booze cruise going, check out our video on craft beer chemistry.

Background

The consumption of organic wine grew at a rate of 3.7% over the year ending September 19, 2009,[1] outpacing growth (of 2%)[2] in the consumption of non-organic wine during a similar period. There are an estimated 1,500–2,000 organic wine producers globally,[3] including negociant labels, with more than 885 organic domains in France alone.[4]

The legal definition of organic wine varies from country to country, be it that the EU sets harmonised rules for all its member countries.[5]

The main distinction in defining organic wine lies in the use or non-use of preservatives, particularly sulfur (sulfur-dioxide (SO₂), sulfites), during the winemaking process.

In the US, no additional sulfites may be added to any organic product, including wine. In the EU, added sulfites are allowed in organic wine and determined by the kind of wine.[6] Most other wine-producing countries do not have their own standards for organic wine and observe the standards of the nation importing the wine.

Another difference in the standards between the US and Europe is the additional label "Made with Organic Grapes." This label can be used in the US if the grapes used to make the wine are 100% certified organic, but the wine has added sulfites (up to 100 parts per million) or uses non-native yeasts.[7] Europe does not have a comparable label.

Production and preservatives

Wine production comprises two main phases - which take place in the vineyard (i.e. grape growing) and in the winery (i.e. fermentation of the grapes into wine, bottling etc.). The baseline definition of organic wine as "wine made with grapes farmed organically" deals only with the first phase (grape growing). Numerous potential inputs can be made during the second phase of production to ferment and preserve the wine. The most universal wine preservative is sulfur dioxide. Therefore, the issue of wine preservation is central to the discussion of how organic wine is defined.

Wine matures over time, and it is widely considered[by whom?] that certain wines improve with aging as the flavors become more integrated and balanced. As a result, the greatest percentage of wines are produced in a way that allows them to last, sometimes as long as decades. The use of added sulfites is debated heavily within the organic winemaking community. Many vintners favor their use for the stabilization of wine, while others frown upon them. Currently, the only effective preservatives that allow wines to last for a long period are 'non-organic'. While there are a growing number of producers making wine without added preservatives, it is generally acknowledged that these wines are for consumption within a few years of bottling.

The various legal definitions of organic wine serve to address this challenge regarding the use of preservatives. In wine produced in the European Union, addition of sulfites, used as preservatives, is allowed in organic wine, but at lower maximum levels than in conventional wine production.[8] It other countries the preservative is not allowed at all in organic wine. In the United States, wines certified "organic" under the National Organic Program cannot contain added sulfites, but wines labelled as “wine made from organic grapes" can.[9]

In 2017, according to the survey "Le bio, c'est bon pour l'emploi" conducted by the UMR Moisa (Supagro Montpellier/Inra),[10] an organic wine farm creates 1.5 times more jobs than a non-organic wine farm. Another finding is that jobs in this sector are more stable. 34.6% of organic farms employ one or more permanent employees against 21.6% in the case of non-certified farms. Similarly, 71.49% of employees are full-time, compared to 66.83% on non-organic farms.[11]

Organic vs. conventional winegrowing

In the US, strict rules govern the organic winemaking process at all stages of production including harvesting, the types of yeast that can be used during fermentation as well as storage conditions. These rules are applied for all imported and domestic wines that acquire USDA certification. In the US, the total sulfite level must be less than 20 parts per million in order to receive organic certification.[12] Organic certification in the UK is more simple as it is based upon the fact that the grapes are grown organically.[citation needed]

Organic certification

Organic certification of wine is complex; different nations have different certification criteria.[13] In the United States, the National Organic Program, run by the United States Department of Agriculture, sets standards for certification of organic foods, including organic wines.[14] In the United Kingdom, organic wine is defined as such made out of organic grapes.[15][16] Some wineries that are technically organic choose not to be certified for various reasons.

Organic certification does not necessarily mean that a winery or vineyard respects human rights and labor rights or ensures gender balance and racial diversity in operations. Labor rights issues have been documented, including in a 2016 film called 'Bitter Grapes' by a Danish filmmaker exposing exploitation of South African vineyard.[17]

Organic certification also does not guarantee use of renewable energy, responsible water use, or more environmentally sustainable packaging.

Natural wine

Natural winemaking is a style loosely defined as using native yeasts in the fermentation process and minimal or no sulfur dioxide in the winemaking process. It may also mean unfined and unfiltered as well. Natural winemaking is not governed by laws in the U.S. and has no inspection or verification process unless it is a biodynamic wine. Estimates are that less than 10 percent of the organically grown wine in the United States is made in a natural winemaking style, most of which is certified biodynamic wine.[citation needed]

Natural winemakers may use organic or biodynamic grapes in their wines. Using native yeasts and relying on minimal manipulation often means that wines have a varying profile from year to year. Different vintages vary more than conventionally made wine because of the non-interventionist approach. This variance is a key part of the natural wine aesthetic.[citation needed]

The natural wine movement has grown in popularity in part as a backlash against the Parkerization of wine,[citation needed] in which a small number of critics' palates and the points system has come to define the market value of wines. The effect of this on wine producers has been to try to manipulate the taste of their wine (for example trying to increase the intensity of fruit and oak) in order to please certain wine critics and get higher ratings.[18] As a result, critics of these critics say this is causing an increasing uniformity amongst wines and a loss of regional and varietal character. The natural wine movement is one response to the global commodification of winemaking.

"Natural" wine should not be confused with “clean wine” which has no definition, scientific standards, certification system, or audits.[19]

Sustainable wines

Some farmers take additional steps beyond standard organic winemaking to apply sustainable farming practices. Examples include the use of composting and the cultivation of plants that attract insects that are beneficial to the health of the vines. Sustainable practices in these vineyards can also extend to actions that have seemingly little or nothing to do with the production of grapes such as providing areas for wildlife to prevent animals from eating the grapes and allowing weeds and wildflowers to grow between the vines.[20] Sustainable farmers may use bio-diesel for tractors in the vineyards to reduce emissions among the vines, or plough with horses.

Sustainable winemaking is a systems perspective of integration of the natural and human resources, involving environmental health, economic profitability, and social and economic equity. These are embodied in the Code of Sustainable Winegrowing Practices Workbook published by the California Sustainable Winegrowing Alliance (CSWA).[21]

Key overall issues that come up in sustainable wine include social concerns such as worker income, health, conditions, diversity, and gender equality. Environmental issues covered by sustainable wine range from wildlife habitat, pest management, to soil health. The question of composting in vineyards spans both soil health and 'zero waste'. Responsible water use in sustainable wine addresses both minimizing water use through techniques such as drip agriculture to wastewater management, particularly in vineyards that use chemicals and are not organic. Sustainability in the field has also come to encompass packaging to minimize the weight of bottles, maximize use of recycled glass in bottles, and explore more environmentally friendly packaging such as boxes. Renewable energy, energy efficiency, and improvements in infrastructure such as capturing and recycling CO2 from alcoholic fermentation also play a role in sustainable wine.[22]
