Is Red Wine Healthier Than White Wine?

By Kerri-Ann Jennings

Whether you prefer white or red wine is generally a matter of taste.

But if you want the healthiest pick, which should you choose?

Red wine has drawn lots of attention for its research-backed potential to lower the risk of heart disease and lengthen your lifespan.

Does white wine have the same benefits?

This article will review what you need to know about red and white wine—how they're made, what to watch out for and which is healthier.

What Is Wine?

Wine is made from fermented grape juice.

Grapes are picked, crushed and placed in buckets or vats to ferment. The process of fermentation turns the natural sugars in the grape juice into alcohol.

Fermentation can occur naturally, but sometimes winemakers add yeast to help control the process.

The crushed grapes are put through a press, which removes the skins and other sediment. Whether this step is done before or after fermentation determines whether the wine becomes red or white.

To make white wine, grapes are pressed before fermentation. Red wine is pressed after fermentation.

After this step, the wine is aged in stainless steel or oak barrels until it's ready to be bottled.

Summary: Wine is made from fermented grape juice. The grapes are picked, crushed and then allowed to ferment in buckets or vats.

What's the Difference Between Red and White Wine?

The main difference between white and red wine has to do with whether the grape juice is fermented with the grape skins.

To make white wine, grapes are pressed and skins, seeds and stems are removed before fermentation.

However, to make red wine, the crushed grapes are transferred to vats directly and they ferment with the skin, seeds and stems. The grape skins lend the wine its pigment, as well as many of the distinctive health compounds found in red wine.

As a result of steeping with the grape skins, red wine is particularly rich in plant compounds that are present in those skins, such as tannins and resveratrol (1).

White wine also has some of these healthy plant compounds, but generally in much lower amounts (2).

Many different grape varietals are used to produce wine, including Pinot Gris, Syrah and Cabernet Sauvignon.

While red varietals are used to make red wine, white wine can actually be made from red or white grapes. For instance, traditional French champagne is made with the red Pinot Noir grape.

Many countries produce wine. Some of the main wine-growing regions are in France, Italy, Spain, Chile, South Africa, Australia and California in the U.S.

While most regions grow several types of grape varietals, some places are particularly known for one or two, such as Napa Valley Chardonnay, Spanish Tempranillo and South African Chenin Blanc.

Summary: Red wine grapes are fermented with the skin on, which gives the wine its color and provides beneficial plant compounds. Grapes for white wine, on the other hand, have their skins removed.

Nutrition Comparison

Red and white wine have very similar nutrition profiles.

However, looking at the nutrient content per 5-ounce (148-ml) glass, you can see that there are some differences (3, 4):

Overall, red wine has a slight edge over white because it has higher amounts of some vitamins and minerals. Nevertheless, white wine contains fewer calories.

Summary: In terms of nutrients, red and white wine are neck and neck. However, red wine has slightly higher levels of some vitamins and minerals.

New Study ‘Reduces Uncertainty’ for Climate Sensitivity

By Daisy Dunne

The latest assessment report from the Intergovernmental Panel on Climate Change (IPCC) estimates that climate sensitivity has a "likely" range of 1.5 to 4.5°C.

The new study, published in Nature, refines this estimate to 2.8°C, with a corresponding range of 2.2 to 3.4°C. If correct, the new estimates could reduce the uncertainty surrounding climate sensitivity by 60 percent.

Worldwide Clean Energy Investments Hit $333.5 Billion Last Year

Global investment in renewable energy hit $333.5 billion in 2018, the second-highest on record, according to a new analysis from Bloomberg New Energy Finance (BNEF).

That's a 3 percent jump from 2016 and 7 percent short of the $360 billion record set in 2015.

How Blockchain Could Boost Clean Energy

By Jeremy Deaton

Bitcoin, the much-hyped cryptocurrency, made headlines recently for driving a surge in power use. Around the globe, digital entrepreneurs are 'mining' bitcoins by solving complex math problems, using supercomputers to get the job done. Those supercomputers use a ton of power, which largely comes from coal- and gas-fired power plants spewing gobs of carbon pollution.

But while hackers wreak havoc on the climate, blockchain, the bleeding-edge technology behind bitcoin, could one day help clean up the mess. Climate wonks say blockchain has a role to play in the clean-energy economy, helping homeowners sell electricity, allowing businesses to trade carbon credits, and making it easier for governments to track greenhouse gas emissions.

Post-Fire Landslide Problems Likely to Worsen: What Can Be Done?

By Lee MacDonald

Several weeks after a series of wildfires blackened nearly 500 square miles in Southern California, a large winter storm rolled in from the Pacific. In most places the rainfall was welcomed and did not cause any major flooding from burned or unburned hillslopes.

But in the town of Montecito, a coastal community in Santa Barbara County that lies at the foot of the mountains blackened by the Thomas Fire, a devastating set of sediment-laden flows killed at least 20 people and damaged or destroyed more than 500 homes. In the popular press these flows were termed "mudslides," but with some rocks as large as cars these are more accurately described as hyperconcentrated flows or debris flows, depending on the amount of sediment mixed with the water.

Birders Get a First Look at How 2017 California Wildfires Affected Wildlife

By Matt Blois

A neighbor knocked on Rick Burgess's door at about 9:30 p.m. to tell him a fire was coming towards his home in Ventura, California. When he looked outside he saw a column of smoke, and the hills were already starting to turn orange. He loaded up his truck with a collection of native plants he was using to write a countywide plant guide, and barely had enough time to get out.

Rover Pipeline Spills Another 150,000 Gallons of Drilling Fluid Into Ohio Wetlands

Energy Transfer Partners' troubled $4.2 billion Rover pipeline has spilled nearly 150,000 gallons of drilling fluid into wetlands near the Tuscarawas River in Stark County, Ohio—the same site where it released 2 million gallons in April.

The 713-mile pipeline, which will carry fracked gas across Pennsylvania, West Virginia, Ohio and Michigan and Canada, is currently under construction by the same Dallas-based company that built the controversial Dakota Access pipeline.

Large Dams Fail on Climate Change and Indigenous Rights

Brazil has flooded large swaths of the Amazon for hydro dams, despite opposition from Indigenous Peoples, environmentalists and others. The country gets 70 percent of its electricity from hydropower. Brazil's government had plans to expand development, opening half the Amazon basin to hydro. But a surprising announcement could halt that.
