10 Breakthroughs in Winemaking

Winemaking has been around for over 8,000 years, and early wines were... quite unpleasant. To improve the flavor, people added everything from ash to resin and even lead [source: Lukacs]. Thankfully, modern fermentation techniques and packaging innovations have drastically improved the taste of wine, making it fresher for longer, and ensuring no one is using lead to enhance its flavor today!

The landscape of wine production has also evolved significantly. Once seen as a drink for the elite in Europe, wine is now produced and enjoyed across the globe, with a good glass of red available just as easily at your local pizza shop as it is at an upscale French bistro.

Winemakers are increasingly aware of their environmental impact. Since high-quality wine begins with top-notch grapes, and healthy grapes require fertile soil, the wine industry is leading the way in sustainable farming practices. Any skilled vintner understands that preserving the environment is not just beneficial for the planet, but it also enhances the quality of their wines.

With such an extensive history, winemaking has seen countless innovations throughout the years, from how grapes are cultivated to how bottles are marketed. Let’s explore 10 key innovations.

10: Biodynamic Viticulture

You've probably heard of organic farming, but what about biodynamic farming? Biodynamic agriculture shares many similarities with organic agriculture, but while organic farming focuses on reducing synthetic inputs like chemical fertilizers, biodynamic farming takes a broader approach. It views the farm and surrounding land as a living ecosystem, using this perspective to determine the best strategies for pest control and optimizing crop yields. Essentially, biodynamics uses organic methods but with a more holistic view, treating the land and micro-climates as vital, living entities that require careful nurturing [source: Morganstern].

More and more winemakers are embracing biodynamic viticulture (grape-growing), not only because it helps protect valuable soil, but also because many believe that grapes grown biodynamically produce superior wine. In a 2004 blind tasting, biodynamic wines outperformed conventional wines in 8 out of 10 cases, with one tie [source: Morganstern]. This means that conventional grapes only outperformed biodynamic ones once in the whole test!

Biodynamic farming began in 1924 but started to gain traction in the wine industry in the early 2000s [source: Morganstern]. Some of the earliest adopters of biodynamic practices in wine production were French vineyards, such as Domaine Leroy and Chateau de la Roche-aux-Moines [source: Reilly].

Since then, biodynamic wine has spread across global wine-growing regions. One of the first American biodynamic vineyards was Ceágo, founded by Jim Fetzer, who previously worked with Fetzer Vineyards [source: Isle]. Today, biodynamic wines come in a variety of styles and flavors.

9: Micro-Oxygenation

The science of wine fermentation has advanced significantly, with techniques like micro-oxygenation influencing the taste of wines. Although oxygen is harmful to wine once it's in the bottle, introducing oxygen during key stages of fermentation can actually enhance the flavor of the wine.

Micro-oxygenation experiments first took place in the 1990s, but the technique began to gain popularity in the early 2000s in regions like France, the U.S., and South Africa [source: Work]. Known as microOX, this method adds oxygen to the wine during fermentation to fine-tune its taste. It can help mellow the flavor of wines made from inferior grapes by softening sharp tannins.

This approach is largely intuitive. Oxygen is gradually introduced after fermentation, and the wine is tasted and adjusted over a period of weeks – sometimes up to three months – until the desired flavor is achieved [source: Work].

Some critics argue that microOX is a blight on winemaking, claiming it results in wines lacking 'character.' However, wine experts counter that the technique simply replicates the natural oxygenation process that occurs when wine ages in an oak barrel or bottle with a cork stopper, where oxygen naturally enters through small pores in the wood or cork [source: Crosariol].

8: Robert Mondavi Puts California Wine on the Map

Although winemaking had been happening in Napa Valley for years, it was during the 1960s that California wines started gaining international recognition, largely due to Robert Mondavi's efforts in marketing.

Napa's first vineyard was established in 1836, with many of its most famous vineyards, such as Beringer, dating back to the late 1800s. Although the California wine industry suffered during Prohibition, the repeal of it in 1933 allowed the industry to bounce back [source: Golden Haven]. Organizations like Napa Valley Vintners worked to expand the market for Napa wines, but it was Robert Mondavi who truly made Napa Valley and California wines a global phenomenon.

In 1966, Mondavi established his winery, and what distinguished his wines from other Napa varieties was his adoption of European winemaking techniques [source: Robert Mondavi]. Unlike many, Mondavi wasn't secretive about these methods; he eagerly shared his knowledge with other winemakers in the region, and that generosity of spirit led to widespread improvement.

A defining moment for California wines came in 1976 during an international wine tasting event in Paris. Two California winemakers, both trained under Mondavi, clinched first place in the competition [source: Robert Mondavi].

Today, California stands as one of the globe's leading wine-producing regions, responsible for 90 percent of the wine produced in the United States [source: Napa Now].

7: Quirky Wine Labels

While not as groundbreaking as establishing a new winemaking region or preserving essential natural resources, the wine bottles with fun or bold labels found on grocery store shelves are an intriguing development in wine marketing.

Winemakers aimed to challenge the perception that wine was only for those with refined tastes. One of the pioneers of this approach was Boony Doon [source: Loutherback]. In the mid-'90s, they replaced their traditional wine label with an image of a man fishing—but instead of catching a fish, he was reeling in Italy, shaped like a boot. If you flipped the bottle, you’d see the same scene from the opposite side.

Later, marketers turned their attention to millennials (born after 1980) with modern label designs featuring quirky logos like cupcakes, playful animals, or cheeky names like Fat Bastard [source: Schultz]. Before this shift, labels usually depicted a bunch of grapes or a chateau—appropriate but not as relatable to younger buyers. The purpose behind these unconventional labels is to trigger positive associations by linking the wine to something familiar and enjoyable, a technique known as "priming" [source: Labroo].

Wine sales have been steadily increasing in recent years, and marketers have discovered that an animal on the label can significantly boost sales. A 2006 study showed that wines with animal-themed labels outsold other wines by a two-to-one ratio [source: Kakaviatos].

6: The Box Wine Revolution

Though many associate boxed wine with cheap, low-quality drinks like Franzia, a growing number of reputable winemakers are opting for box packaging, offering a more sustainable option for wine storage.

Boxed wine made its debut in the mid-1900s, but it wasn’t until the 1980s that it gained traction in U.S. stores as a viable alternative to jug wine [source: Lefevere]. By the early 2000s, premium wines began appearing in boxes, signaling the start of the box wine revolution. Its eco-friendly advantages are among the primary reasons for this comeback.

Yellow + Blue, an organic winemaker, exemplifies a sustainable approach to wine by filling eco-friendly boxes with high-quality wine. I was initially skeptical when my husband brought home a box of their Malbec, but it turned out to be just as delicious as bottled wines at a similar price point.

While the box may not have the elegance of a glass bottle, its lighter weight makes it easier and more cost-effective to transport. This reduction in weight means that shipping requires less energy, which in turn leads to fewer greenhouse gas emissions [source: Yellow + Blue].

Wine boxes are also effective at preventing oxygen from entering after they’re opened, extending the wine’s shelf life and reducing waste [source: Lefevere]. While some exposure to oxygen is beneficial during fermentation, it can ruin the flavor once the wine is ready. Boxed wine may taste the same initially, but the key advantage of the box is its ability to keep the wine fresh longer by sealing out the oxygen.

5: Canned Wine

Though not as widespread as boxed wine just yet, canned wine is another innovative packaging option that is transforming how we enjoy this alcoholic beverage.

In 2003, Australian winemaker Barokes Wines introduced the first wine in a can. The secret to packaging wine in metal containers lies in a special liner. Without it, the wine would absorb the taste of the can and could even corrode the container over time [source: Tsui]. The first U.S. winery to offer canned wine was filmmaker Francis Ford Coppola's, who released his Sofia line of canned wines the year after Barokes Wines [source: Tsui].

Much like box wine, one of the main advantages of canned wines is the reduced exposure to oxygen once the wine is sealed. However, cans manage this with a simpler approach: because canned wines are typically single-serving, you don’t risk exposing an entire bottle to oxygen when you only want a single "glass."

The single-serving format of canned wine makes it ideal for on-the-go occasions, especially in places where glass containers are not permitted. Think picnics, sporting events, or poolside gatherings. Plus, there's no need for plastic cups—just sip directly from the can.

Like boxed wine, canned wine has the added benefit of being lighter than glass bottles, which reduces its carbon footprint during shipping.

4: Wine on Tap

For some, wine can feel a bit daunting, but that's where the wine-on-tap concept shines. In lively city areas, wine bars are offering patrons the chance to taste or pour wine from taps themselves.

While some bars have bartenders serving wine from taps, I've visited places where customers can do it themselves. The most common self-service setup involves purchasing a card to swipe at any tap, where you can opt for a small taste (1-2 ounces) or a full glass. This self-serve approach is incredibly inviting, allowing customers to explore different wines without the pressure of an expert overseeing them.

Like many modern serving techniques, wine on tap brings environmental advantages. It helps reduce wine waste in restaurants by preserving the wine for a longer period. Once the bottle is tapped, it remains largely untouched by oxygen. This is beneficial for store owners because wasted wine represents lost profit. Switching to wine on tap can save bars up to 25 percent of their wine purchases [source: Wine on Tap].

Wine on tap also contributes to reducing packaging waste. While some establishments serve single bottles on tap, it is more common to use a keg. This results in less packaging, reduced shipping expenses, and a smaller carbon footprint.

3: Turning Wine Waste into Fuel

Innovation in the wine industry isn't limited to marketing and packaging. As you've probably noticed, winemakers are quite environmentally conscious, so it's no surprise that many wineries are finding ways to repurpose the vast waste from pressed grapes (over 100,000 tons or 90,718 metric tons in California alone) into alternative fuels.

Much like biofuel production from other agricultural byproducts, turning grape waste – known as 'grape pomace' – into biofuel involves using microbes to break down sugars into water and hydrogen, which is then converted into energy [source: Choi].

In collaboration with the Napa Wine Company, researchers from Penn State have been working since 2009 to transform wine waste into fuel [source: Gangi]. This process produces hydrogen, which is then used to create biofuel, along with wastewater. After some treatment, this wastewater is reused to irrigate grapevines. Even better, visitors to the vineyard can now see alternative energy demonstrations as part of their wine tour experience!

One of the challenges of turning wine waste into fuel is that grape stems, seeds, and skins lack significant sugar content since most of the sugar is used in wine production. These byproducts could become far more valuable if researchers could convert more than just the sugars into biofuel. Danish chemist Yi Zheng is working on a solution by developing a method to turn cellulose from the skins and seeds into ethanol, greatly improving the efficiency of grape pomace as a biofuel feedstock [source: Schrope].

2: Bring on the Bubbly!

Do you uncork a bottle to celebrate the New Year? You can trace the tradition back to a long line of sparkling winemakers, stretching from ancient Roman times to a visionary French monk.

Sparkling wine has existed far longer than modern Champagne. In fact, it likely originated about 1600 years ago, when ancient Romans began cultivating grapes in the Champagne region of France.

While Dom Perignon might not have been the first to invent Champagne—since sparkling wines predated his work—he developed a technique to make white wine from red grapes, a cornerstone of modern Champagne production. Additionally, around 1693, Perignon sought to create a Champagne without bubbles, believing that oxygen harmed wine. Fortunately, he was unsuccessful, and the techniques he refined are still used today to produce the sparkling bottles we enjoy.

Champagne and other sparkling wines achieve their signature bubbles through a unique two-step fermentation process. Winemakers add yeast and sugar to the wine for a second fermentation, during which the yeast consumes the sugar, producing carbon dioxide. These bubbles, which give Champagne its effervescence, are a direct result of this secondary fermentation process [source: Polidori].

For centuries, Champagne producers have been fiercely protective of their grape-growing and winemaking techniques, as well as the right to use the region's name on their bottles. Only sparkling wines produced in France's Champagne region are permitted to be labeled 'Champagne' [source: Galante].

1: Diet Wine

We have diet sodas and diet cookies, so why not diet wine?

Brands like Weight Watchers have begun crafting low-calorie wines to cater to the diet-conscious market. The key to these wines is that fewer calories typically result from a reduction in alcohol content, since alcohol contributes most of the calories in wine [source: Tepper]. While sugar might seem like the major culprit, alcohol actually packs nearly double the calories per gram compared to sugar. Therefore, reducing alcohol content is the most effective method to lower the calorie count in a bottle of wine [source: Noelcke].

Weight Watchers launched its low-alcohol wine in the U.K. and Australia in 2012, containing only about 8 percent alcohol, which is quite low for wine [source: Tepper]. The company has not released specific calorie details, making it difficult to determine exactly how many calories their wine saves compared to regular varieties [source: Evon].

In the U.S., Skinnygirl, known for its line of low-calorie cocktails, entered the diet wine market in 2012. It claims to offer a 100-calorie glass, but in reality, most wines with 12 percent alcohol already contain around 100 calories per glass. A 12 percent alcohol level is fairly typical for wine, although some wines may have higher alcohol content and therefore more calories [source: Kaplan]. Therefore, finding a low-calorie wine doesn't always mean seeking out a specifically labeled 'diet' version.
