Prosecco—Italy's sparkling wine—is produced using the tank method

Cava is Spain's sparkling wine

Champagne is delicious, but it’s not the most budget-friendly beverage. Cava is a Spanish wine produced through the same traditional method used to make Champagne but often sold at a lower price. Cava can be produced in several different regions, offering the possibility of more diversity than what is typically found in Champagne.

Why only a single region can call it Champagne

Champagne isn't just sparkling wine—it's a product of strict tradition and geography. By law, only bottles made in France's Champagne region using the "méthode champenoise" can bear the name. From fermentation to riddling and disgorgement, each bottle undergoes years of meticulous crafting before it's ready to be popped.

How disgorgement works while making sparkling wine

After riddling, winemakers still need to dispose of collected sediment in wines. While this was once done by hand, the modern method of freezing the bottle's neck and removing the now-solid sediment is ubiquitous. In this short video, an enologist (wine expert) from California’s Halter Ranch vineyards explains each step of the mechanical disgorgement process, complete with footage from their production line.

Sparkling wine was a political tool in the Soviet Union

To show the world that the Soviet Union had recovered after the devastating famine of the early 1930s, leader Josef Stalin turned to a surprising source: sparkling wine. Stalin believed that if everyday citizens could access luxury goods like caviar and Champagne, it would show socialism had succeeded. The result was Sovetskoye Shampanskoye, a Soviet-made sparkler that achieved his goal of availability and affordability if not quality.

Dom Pérignon was a 17th-century French monk often inaccurately credited with inventing Champagne

You’ve probably heard of Dom Pérignon the brand, but what do you know about Dom Pérignon the man? He is often credited with inventing Champagne—which is why the iconic (and expensive) Champagne house is named after him—but the truth is he simply pioneered many methods for manufacturing it.

The tradition of drinking Champagne on New Year's is believed to come from ancient Rome

Julius Caesar might not have had sparkling wine, but when the Romans created the now-standard calendar that begins on Jan. 1, they celebrated with a toast. The tradition spread throughout Europe and then the colonies, and so when Champagne became the drink of choice for special occasions, it was only natural that it became the standard New Year’s Eve sip.

Britain’s bottle innovation saved Champagne

Champagne wouldn’t be where it is today without a surprising partner: 17th-century British glassmakers. An energy crisis caused by deforestation—not enough trees to burn—led to the search for an alternative fuel source. Enter coal. The plentiful resource burned much hotter than wood, creating stronger glass that could stand up to the pressure of the carbon monoxide produced by the wine’s second fermentation and solving one of the fledgling industry’s most vexing problems.

Wine explained

Wine is the sublime product of fermentation, the process of breaking down fruit—typically grapes. As the grapes ferment, yeast consumes the natural sugars and converts them to alcohol. With the process first developed and refined thousands of years ago, wine has been a central feature of celebrations throughout modern history. Want to learn more about its origins?

Watch underwater photosynthesis make water look like champagne

In shallow waters where sunlight can reach, photosynthetic reactions absorb water and dissolved carbon dioxide, producing bubbles of oxygen at the surface of plants. As these bubbles rise to the water's surface, a fizzy appearance is created.

Distinguishing club soda, seltzer, and sparkling water

The three forms of drinking water are similar, but their differences lie mostly in the presence and proportion of minerals and carbonation. Read this quick explainer on the major differences.

A quick guide to rosé wine

What is a rosé? Rosé wines are technically reds, though they’re typically served cold and have more flavor characteristics in common with white wines. This primer explains the basics of the fastest-growing wine category in the US. It covers production and rosé-making regions and styles, along with some common tasting notes for each bottle.

The robust wine production of Antarctica

Antarctica might not be known for its agriculture, but parts of its unique climate are suitable for growing wine grapes. Most of the wine produced there is icewine, a style of dessert wine commonly found in Canada and Germany. This guide covers Antarctica’s unique soil composition, grape varieties, and how exactly penguins contribute to this unusual wine-growing region. There’s even a recommendation for an Antarctic tasting room for adventurous souls.

The Italian music contest that inspired Eurovision

Italy's Sanremo Festival began in 1951 as a way to boost tourism in the Italian Riviera during the offseason, with three acts performing original songs on a national radio broadcast. The format would be replicated five years later by Eurovision, though Sanremo is still around.

The difference between ice cream, gelato, sorbet, and Italian ice

Ice cream is made of eggs and is high in fat, served cold. Gelato, on the other hand, has more milk and less cream, and is typically served warmer than ice cream. Sorbet is dairy-free and often includes alcohol, while Italian ice is grainy, lighter, and low in calories (and often doesn't contain dairy).

Ancient Romans helped develop modern cheese production techniques

The ancient Romans loved cheese and experimented with different processes to elevate its flavor, like aging. Some of their innovations, like Pecorino Romano, you can still find today. Others, like the smoked goat-milk Caseus, we only know about through historical records.

Shakespeare’s use of verse and prose signifies important characteristics

Structured verse signals formality, often used by high-ranking characters; in contrast, unstructured prose is typically used in informal, more witty situations by lower-status characters.

Tequila is uniquely prone to busts, as agave plants take 6 years to grow

Most liquors derive from products that are grown annually and age in barrels for years, like whiskey and wine. Tequila comes from blue agave plants in Mexico, which require six years of cultivation before they can be processed. This makes tequila particularly prone to speculative bubbles, like the one occurring in the mid-2020s.

Learn how helium is used in the US, the world's largest producer of the noble gas

About 44% of the global supply comes from the US, as much as the next two biggest producers—Qatar and Russia—combined. According to the US Geological Survey, more than half of this helium is used in scientific and engineering equipment (22%), non-welding-related manufacturing and fabrication (17%), and as a lifting agent (17%).

Protein content and multiple fermentations create beer foam stability

Single-fermentation beers rely on protein viscosity for foam, with lipid transfer proteins transforming into stabilizing structures during fermentation. Scientists believe foam research may result in safer lubricants for electric vehicles.

Humor during Mussolini’s fascist regime

Benito Mussolini’s fascist regime in Italy strictly censored humor, closing down popular satirical publications and even punishing certain jokes with prison sentences.
