Tannins contribute to a wine's composition

A guide to white wine

Aside from color, how does white wine differ from red? This comprehensive guide to white wine covers everything from grape varieties to production methods to aging techniques. It provides explanations for several common white wine blends as well. You'll also discover an overview of tasting notes for several popular white wines, and suggestions for foolproof food pairings like brie and Chardonnay.

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.

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.

How texture affects taste

Texture is the brain's interpretation of several sensations, including pressure, as registered by our teeth, tongue, and finger tips, and sound, as recorded by our ears. Texture also speaks to food particle sizes—smaller than 35 microns contributes to the sensation of creamy—and the balance between flavor and mouth time, such as the crunch of a crispy chip or the bounce of a chewy caramel.

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.

Breaking down various tongue disorders, from infections to genetics

Taste is one of our fundamental senses, but can be impeded by a wide variety of conditions including glossitis, angioedema, and black hairy tongue. Most are characterized by their color, shape, and sometimes change in function. Causes range from vitamin or mineral deficiencies to fluid accumulation, fungal infection, or more.

Napa's growing conditions are unique

The French term "terroir" refers to the "sense of place" that growing conditions impart on a wine. Because the Napa Valley is surrounded by mountains on three sides, the combination of cold air from the Pacific coast and warm air from inland leaves Napa's wine with a distinct terroir.

The top wine-producing countries in the world

Three European countries dominate the world in wine production: France, Italy, and Spain. This table lays out how the world's top wine-producing countries compare in terms of annual volume, with Europe and the United States comprising the bulk of production. Visualize the country-by-country difference with this bar graph.

Explaining concentrate and how concentrate-derived juice differs from its source

Developed to reduce the volume of goods—thus lowering storage and shipping costs—the concentration process uses pressure and heat to remove water, pulp, and skin from fruits. Concentrates provide significant flavor, sugar, and calories to foods in small quantities, but do not retain most of the fiber, vitamins, and other nutrients from the source fruit.

How bitter taste receptors help guard against infection

Receptors for "bitter" tastes evolved to detect potentially harmful plant chemicals, such as nicotine. The receptors also trigger bacteria-fighting responses, including waving hairlike projections to bat away bacteria, ordering the release of bacteria-killing nitric oxide, and calling for antimicrobial protein reinforcements.

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.)

Understanding the biochemistry of ingredients and taste can improve flavor and texture

Keeping eggs at room temperature produces smoother batters when baking, and doing the same with tomatoes helps prevent a mealy, granular mouthfeel. Salting meat a day before gives more time for proteins to break down, improving flavor and tenderness, while cooking vegetables in well-salted water can lock in nutrients and color.

Pigments in paint can come from rocks, plants, insects or synthetic sources

Paint's composition is varied through the combination of pigments with binding agents. In the past, artists created their own paints by mixing pigments with water, oils or egg yolks to bind the colors together.

Tick saliva has a numbing agent so you won't feel the bite

Tick saliva has a variety of built-in assets that enable them to go undetected and continue feeding on their prey: They use saliva to form a hard seal around themselves to keep them in place while they feed for a few days, a numbing agent so you don't feel the bite, and even natural anticoagulants to keep blood from clotting.

Your DNA may determine whether you like coffee or tea

Whether people prefer coffee or tea may boil down to a matter of taste genetics. People with a version of a gene that increases sensitivity to the bitter flavor of caffeine tend to be coffee drinkers, according to a report. Read on for more.

The strange endurance of consuming blood for health

Blood's importance to humanity is best summarized this way: without it, we die. This importance naturally begets assumptions about its medicinal properties, many of which appear accessible through drinking or eating the fluid connective tissue. This article details the history of blood drinking, from ancient Roman gladiators to modern-day sanguinarians.

Transpiration drives water movement through a plant’s vascular system

Water evaporates from the leaves, creating tension that pulls more water upward from the roots through the xylem—the equivalent of plant blood vessels. This process is supported by water molecules sticking to each other (cohesion) and xylem walls (adhesion).

Red blood, skin, hair, and nail cells destroy their DNA upon maturing

To maximize the amount of oxygen they carry and more easily alter their shape to fit into narrow blood capillaries, red blood cells destroy their own nuclei. Cornified cells found in hair, nails, and the outermost layer of skin destroy their nuclei and other cellular contents to make room for keratin, which provides durability and structural support.

Canada is the largest foreign buyer of California wine

Tariffs have impacted the wine industry in Canada significantly, given that California winemakers are responsible of 80% of the country's wine supply.

Tinnitus is derived from the Latin verb tinnire, meaning to ring

Alcohol is responsible for 5% of cancer cases and 4% of cancer deaths in the US

Alcohol consumption is linked to at least eight different types of cancer, including liver, breast, and throat. The risk comes from ethanol, which turns into DNA-damaging acetaldehyde. Experts recommend limiting intake or quitting altogether to reduce long-term health risks.

Natural toxins produced on plants or consumed by animals may cause food poisoning

When humans eat plants with certain natural toxins on them—including a family of toxins called aflatoxins that fungi produce on crops like peanuts and corn— they can become ill with food poisoning. Toxins can still harm humans even if animals or plants appear fine to the human eye. The World Health Organization advises that we should throw away moldy or discolored foods, refrain from eating wild plants or mushrooms that aren’t definitively nonpoisonous, and remember that just because something is “natural” it’s not always safe to eat.

Explore a gallery of tardigrades

Although sometimes called moss piglets, tardigrades are most often white or clear with some dark pigments. Tardigrades only move by crawling, not swimming, and depictions of organisms with caved-in heads or other coloration result from sample preparation for microscopes.

Poison ivy is in the same family as mangoes, cashews, and pistachios—and they all produce oily urushiol in their raw, unprocessed state—but they are typically prepared in ways to avoid causing human discomfort.

Touch deprivation can heighten anxiety and depression

Pacinian Corpuscles are pressure receptors just under the skin that send signals to the vagus nerve in the brain—that's the cranial nerve which regulates involuntary actions like breathing, heart rate, and the general "fight or flight" response. Activating those receptors can slow the heart, decrease blood pressure, and lead to the release of oxytocin and cortisol. The absence of touch, conversely, can promote negative feelings.

Vitamins are micronutrients human bodies need but don't naturally produce

Each vitamin is found in specific portions of a normal human diet and supports normal human functioning in distinct ways. Vitamin A is found in red meat, carrots, and potatoes and supports vision and skin health, while Vitamin D (common in fish and mushrooms) helps absorb calcium. See sources and uses of each vitamin with this chart.
