These are the wine regions in jeopardy due to climate change, study says

How climate change is affecting the wine world

Climate change is altering every aspect of the world we live in, and that’s especially the case for agriculture. The wine industry continues to adapt, from making English sparkling wine to treating smoke impact from increased wildfires.

A new study published in Nature paints a pretty bleak future for wine, at least in some iconic growing areas. The study estimates that up to 70% of top wine production areas on the planet will no longer be suitable by the end of the century. That’s dire news for places like California, Greece, Italy, and more.

Wine has been evolving alongside climate change for years, and all hope is not lost. However, the industry will have to continue evolving to keep pace, experimenting with new growing methods and potentially new vineyard areas.

Most of the wine map resides in more temperate areas not too far from the equator. Yet, thanks to rising temperatures and more extreme weather, this map is shifting. Regions that are particularly vulnerable include warmer areas like Mendoza, Australia, California, and the southern stretches of Italy and Spain.

These regions have already seen significant shifts, like heat spikes and drought, that lead to earlier harvests. On top of that, all that increased radiation (not to mention CO2, as the report points out) has negatively affected grape quality and forced some producers to grow elsewhere or not at all.

Moreover, an estimated 30% of the most affected wine regions are experiencing conditions too dramatic for premium wine production to continue. That’s a sobering pill to swallow for some of the planet’s most well-known wine zones, from Malbec to Provence.

Ways to adapt

The adaptation game has already begun. Over the last several decades, we’ve seen wine producers seek out cooler, more suitable land for cultivation. They’ve planted estates at higher elevations, and regions once thought irrational for premium wine production (Colorado, Vermont, the Midwest) are showing promise. Of course, this expansion leads to potential run-ins with natural areas, disputes over conservation, and natural resource depletion.

The industry will have to get smarter and is showing signs of doing so. More drought-resistant grape varieties are being championed, and sustainability has become a way of life. Traditional farming methods have given way to more natural approaches, and producers are trying their hand at making new wines to honor the warmer growing seasons.

Will new wine regions emerge?

Undoubtedly, new regions will emerge, and in many cases, they already have. New appellations are popping up all over the globe (otherwise known as American Viticultural Areas here in the U.S.), pushing farther and farther from the equator to avoid extreme heat and weather (hail and excessive rain cause problems too, damaging buds and introducing disease, etc.). Look for places in northern Europe to shine, as well as cooler domestic pockets like the Pacific Northwest.

The most startling conclusion could be once-famous winemaking areas going extinct. Places like the Barossa Valley in Australia and Paso Robles may one day soon simply be too extreme weather-wise for wine.

Wine barrel barrique

Walk into any winery on planet Earth and you’re sure to run into a barrel or two. Most commonly, these barrels are barriques, the wooden vessels made famous by vintners in Bordeaux and known for their ability to gently bring a wine from fermented juice to something well integrated and special.
Think of the barrique as the most common size of wooden barrel out there. It holds 225 liters, or about 59 gallons, making it immensely heavy when full (over 500 pounds). Yet, thanks to barrel racks and forklifts, it can be stacked elegantly in cellar spaces and climbed upon by intrepid cellar hands carrying out their day-to-day winemaking tasks.

Wine glut? More like wine deals

Many people would contend that there's no such thing as too much wine. However, recent global data suggests that we're experiencing a global wine glut, with more supply than demand. In fact, the surplus is so great that some growers are ripping up their vines and using their land in other ways.

The glut began to appear last year, but its sources all go back to around 2020.

This is what wine tasted like in ancient Rome, and we have thoughts
Here's what Roman wine tasted like

Wine and people go way back. The oldest evidence of the stuff goes back more than 8,000 years, in what is now the Republic of Georgia. Then came the Romans, who perhaps made and guzzled the most wine of any era or empire.

Research has revealed how these wines were made, but what did they taste like? Archeologists have cracked the code, as revealed via a new study published in Antiquity. The wine was most akin to the skin-fermented and slightly oxidized wines that are trending today -- aka, orange wines. According to the report, the wine boasted notes of bread, apples, and walnuts. Researchers even used curry as a means of describing the aromatics of these wines.
Why such a flavor?
