Although vinegar was first discovered when wine was left to sour after exposure to air, the fermentation of different base ingredients contributes to the variety of vinegars seen today.

How fermentation enables the pickling of food and the production of beer

This process occurs when microbes produce lactic acid, ethanol, or carbon dioxide after consuming sugars. The acid helps preserve vegetables in a brine solution during pickling and gives them a sour taste, while ethanol serves as the inebriant in alcoholic beverages. The acid and carbon dioxide give sourdough bread its taste and texture.

How fermentation works

Alcoholic fermentation is the process where yeast transforms grape sugars into ethanol, creating wine. Microscopic fungi (commonly known as yeast) metabolize sugars, producing alcohol and carbon dioxide. Fermentation's speed and temperature impact wine's flavor and style: cooler temps suit fruity whites, while warmer ones enhance red's tannins. Fermentation stops when sugars are depleted or by temperature extremes, and sometimes yeast removal yields sweeter wines. Get a quick breakdown of the process with this easy explainer.

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?

It also includes in-depth explanations of what to look for in their wines, including common grapes, stylistic choices, and tasting notes.

Strict rules dictate the making of Champagne

Some regulations, such as geographical area and grape varieties, are fairly well known. But to be true Champagne, winemakers must follow guidelines for all sorts of finicky things, including pruning, press yield (how much juice is extracted from the grapes), alcohol content, vineyard management, and aging, among others.

The importance of volatile aroma compounds in the flavor quality of food

Processes such as air movement and heating cause food to lose aroma molecules, which studies have shown play a major role in our sense of taste. While losing these molecules to the environment leaves fewer to be processed during consumption to intensify flavor, it can also produce previously nonexistent aroma compounds or release previously trapped ones, altering or enhancing the food's flavor.

The research that led to sour

Scientists are trying to figure out if there are unique receptors that respond to the molecules that make up flavors we associate with calcium, blood, batteries, and other items that often escape dinner menus. Taste researcher Dr. Danielle Reed says the minimum evidence for a taste category typically involves identifying dedicated receptors and then removing them to show the taste vanishes.

Wine is divided between Old World and New World

The distinction stems from both geography and winemaking technique and tradition. This video breaks down how different viticultural regions fit into each category and the common traits of both Old World and New World wines. It also provides helpful tips for reading Old World wine labels.

How science came to understand umami

Before Dr. Kikunae Ikeda sat down in 1907 and pondered the taste of dashi, scientists typically agreed upon four types of taste: sweet, salty, bitter, and sour. He boiled 90 pounds of kelp into a resin that he then stripped of different compounds until he was left with a single ounce of brown crystals. Testing later revealed these crystals were glutamate, an amino acid and one of the protein's building blocks.

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

Italy’s best-known sparkling wine, Prosecco, has many similarities to Champagne. However, Prosecco performs its secondary fermentation in a different manner. Rather than taking place in the bottle using the French method, fermentation of Prosecco takes place in large, pressurized steel tanks, making it easier to produce on a large scale. The technique results in light, fresh flavors and plenty of bubbles.

The invention of cheese likely came from a fruit fly landing in a pail of fermenting milk

The chance encounter around 5,500 years ago laid the groundwork for cultured milk products like yogurt and cheese. Over time, microbes evolved in tandem with goats, sheep, and wheat to give us the wide variety of cheeses that we enjoy today.

The vast majority of Champagne is labeled 'dry' or even 'extra dry'

Sweetness levels are determined by the amount of sugar added to the wine at the end of the process—anything up to 6 grams per liter is extra dry, and up to 12 grams per liter is still considered dry.

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.

Napa Valley was the second officially sanctioned wine-growing region in the US.

Budweiser still uses the same yeast lineage derived from the one used in the 1800s

During the late 1800s when Budweiser beers hit the market, darker, all‑malt lagers dominated the US beer market. Budweiser was brewed with a single, consistent yeast strain that gave it a crisp uniform flavor, differentiating it from darker beers.

The five most common chemicals found in modern food

Most modern processed foods rely on a number of preservatives to stay fresh from production to our plates. The most common include citric acid (preservative and flavor), sodium benzoate (preservative), xanthan gum (thickening and stabilizing), carrageenan (thickening), and red dyes 3 and 4 (for color).

The preferred barbecue sauce depends on your location

America's regional barbecue styles include multiple highly specific sauces. From the tart, acidic vinegar-based sauces of North Carolina, to the thick, sweet-spicy Kansas City variation, American barbecue sauces are as varied as the country’s geography.

A blind taste test in 1976 determined that California produced better wine than France in a decision known as 'the Judgment of Paris' that realigned the wine world.

Barbecue relies on a unique scientific equation

Barbecue's distinct flavor starts with an interaction between the heat source and food, which creates a Maillard Reaction—better known to diners as those crunchy, caramelized bits on the outside.

How beer became a part of medieval culture

This history of beer's evolution during the Middle Ages unpacks how the brewing process, which killed harmful bacteria, made beer a safe alternative to water. That fact, along with the Catholic church condoning (and, in some cases, producing) the beverage, helped it evolve into a major commodity.

Napa Valley became a player on the international stage in the mid 1970s, when judges in a blind taste test deemed its wine superior to France's.

Researchers believe beer was being brewed 13,000 years ago

In 2018, archaeologists discovered traces of a wheat-and-barley-based alcoholic beverage near Haifa, in modern-day Israel, and believe it was produced by the Natufian people.

View a detailed list of Napa Valley wines, dating all the way back to the 1991 vintage.

Champagne’s fizz used to be considered a flaw

The bubbliness that we love now was once considered a winemaking failure. In fact, Dom Pérignon probably would have referred to it by its common nickname at the time, "vin du diable," or devil’s wine. The wine’s volatility often caused bottles to explode, which was both dangerous and costly. It wasn’t until the development of sturdier bottles and more consistent winemaking techniques that popularity truly soared.

There are 6 essential steps in cheesemaking

The six basic steps that are required to turn milk into cheese start with acidification and end with ripening (aka aging). This guide explains what happens at each step and how it contributes to the finished product.

How a modern 'beer archaeologist' crafts ancient ales

The short documentary follows Travis Rupp, a University of Colorado classics professor who also works with Avery Brewing to produce Ancient Egyptian, Roman, and Peruvian beer.

Unlike fruits, the category of 'vegetables' is a culinary term, not a scientific one

Within botany, fruits are defined as the ripened ovaries of flowering plants, and include apples, grapes, tomatoes, avocados, green beans, peppers, and almonds. In the kitchen, "vegetables" is an umbrella term that encompasses many fruits and other parts of plants, such as leaves (lettuce, kale) and roots (carrots, beets).
