A root lice infestation once destroyed over 80% of Napa's vines

Wildfires have seriously affected Napa's winemaking

If there’s a single thing that has defined the last decade of California winemaking, it’s the effects of climate change, particularly wildfires. To avoid the threats of wildfires, some vineyards have pivoted to more heat-tolerant grapes.

The Gold Rush helped turn Napa into wine country

In the 1830s, the arrival of settlers carrying European rootstock grapevines to Napa kick-started the valley's wine industry. Ten years later, the Gold Rush brought scores of wine-loving Europeans and their descendants to the area. Recognizing an opportunity, Charles Krug opened the valley's first commercial winery in 1861, which produces bottles to this day.

Napa produces only 4% of California's wine

Despite its reputation, the Napa Valley has a modest share of its state's annual wine production. The valley's over 400 wineries produce only 4% of the state’s wine.

In 1910, riots swept Champagne over unfairness in the winemaking industry

The French are well known for protesting, and their winegrowers are no exception. After years of disastrous harvests caused by bad weather, disease, and deceptive practices by large Champagne houses, smaller vintners fought back.

How winemaking has changed throughout history

Winemaking is an ancient practice, and researchers continue to find evidence that this ritual came even earlier than previously estimated. This article outlines five key turning points in wine’s history, from the fermentation of fruit by our primate ancestors to today’s increasingly popular “New World” wine. Discover the fascinating scientific and cultural factors that led to wine’s changes in flavor and increased symbolic importance.

The numbers on US wine consumption

Ever wonder how much wine the average American drank in 1949? Wonder no more! The answer is 0.89 gallons. That’s way less than 2022, where the number has quadrupled to 2.86 gallons. Check out this simple table that tracks average United States wine consumption from 1934 through 2022, by individuals and as a whole. American wine consumption peaked during the early pandemic but has lessened since then.

Red wine, 101

How does a bottle of red wine get to the table? In this podcast episode from VinePair, tastings director Keith Beavers covers this wide-ranging wine category.

Why your wine smells unpleasant

Ever had the experience of receiving a bottle of wine with a janky, less-than-favorable odor? This Esquire article ventures to answer this question and offers the explanation that the culprit is likely corked wine. Read to understand why corks can create a moldy or musty scent, and feel emboldened to send a corked bottle back for something with improved quality.

Bacteria have been genetically engineered to bioluminesce when wine has spoiled

Developed by researchers at Hebrew University, the method involves the firefly enzyme luciferase, which emits light from within bacteria expressing when they are in the presence of acetic acid vapors produced by wine. The process provides affordable, on-site, real-time monitoring of fermentation quality.

How scientists know invasive nutria were likely introduced to California by humans

Although native to South America, DNA testing of the semiaquatic rodents showed they are closely related to a population in Oregon, suggesting they were deliberately transported into the state. First identified in the San Joaquin Valley in 2017, the distance, terrain, and lack of nutria between the two regions has allowed researchers to rule out natural migration.

Some fine wines are considered alternative investments that could grow in value over time.

The use of fungi to detoxify land and water—a process known as mycoremediation—has been used to clean up natural resources affected by the 2025 California wildfires.

Volcanic activity may have triggered the Black Death by spewing gases that led to crop failures in Europe, thus forcing the import of grain ships with plague-infested fleas.

Poison ivy was sent to Europe in the 1600s as an exotic, ornamental oddity, where it was purposefully grown in the English royal gardens at Kew, the Faculty of Medicine in Paris, and a few other locations.

Watch Cordyceps, a parasitic fungus, turn an ant into a ‘zombie’

This National Geographic TV clip shows how a parasitic Cordyceps species—sometimes colloquially called the “zombie ant fungus”—controls an ant’s behavior and kills its host. The fungus can rapidly wipe out entire insect colonies.

The ancient Romans invented the first known artificial sweetener—it involved lead

The product was known as "sugar of lead." It was made by boiling wine in lead pots, concentrating the grapes' natural sugars and adding sweetness from the lead that leached into the grapes. The substance was used until roughly the 1880s for medicinal purposes and also to sweeten wine. (Some users may encounter a paywall.)

Human beekeeping has been traced back to 7000 BCE

Eighty-seven of the world's leading crops rely on pollination in some way, including 43 that are highly dependent or entirely reliant on it. Without pollinators, key foods such as apples, avocados, and almonds would likely become extinct, pushing entire ecosystems into collapse.

How microbes limited the damage and helped clean up the Deepwater Horizon oil spill

A bloom estimated to contain about 100 sextillion microbial cells broke down much of the 4.1 million barrels of spilled crude oil into nontoxic compounds in what was one of the most significant bioremediations of a human-made disaster. The microbes involved acted similarly to the first patented genetically modified organism in US history: an oil-eating bacterium engineered in 1971.

Oktoberfest has been canceled 26 times

The first time, in 1813, Bavaria was fighting off Napoleon’s army, which left little time for celebration. Years were also lost to the Austro-Prussian War, a worldwide cholera outbreak, and both World Wars. Most recently, the 2020 and 2021 Oktoberfests were canceled due to COVID-19.

LSD was derived from natural compounds produced by the ergot fungus

Ergot is a fungus that slowly infects and replaces individual grains on grasses, including rye and wheat. Ingesting ergot can cause ergotism, a form of poisoning with symptoms—including headaches, hallucinations, gangrene, and convulsions—varying by season and geography. This grain was used for medicinal purposes as early as the 1500s.

Horses account for about 96% of the known mammalian cases of West Nile beyond humans

That's partly because horse owners likely notice and take veterinary action when their animals get sick. There is no way to know how frequently wild animals are getting infected with the virus.

Up to 225 cases of leprosy in the US are diagnosed each year

Most cases in the US are imported, meaning someone was infected in a country where it was more common. Since symptoms can sometimes take decades to appear, tracing the origin of the disease can be hard.

In the early 20th century, pneumonia was a top cause of death worldwide, often fatal without effective treatment. Penicillin turned a once deadly infection into one of the most treatable bacterial diseases.

Explore the archaeological treasures of Pompeii, the city buried under volcanic ash when Mount Vesuvius erupted in 79 CE.

How powerful was the volcanic blast that destroyed parts of ancient Rome?

This article details how strong Mt. Vesuvius' powerful 79 CE blast may have been. Pompeii lay a bit further from the volcano's slopes than Herculaneum, a smaller seaside city. While Pompeii was mainly destroyed by ash and lapilli—glassy fragments of lava ejected during volcanic eruptions—Herculaneum was first hit by a scorching pyroclastic cloud of volcanic gas and other matter.
