Barley grows on every continent except Antarctica, with global production reaching about 153 million metric tons in 2025. It thrives in cool, temperate climates and tolerates a wider range of conditions than most cereal grains, which is why you’ll find it cultivated from sea-level plains in Northern Europe to highland plateaus in Tibet above 4,700 meters.
Top Barley-Producing Regions
The European Union dominates global barley production, growing roughly 56 million metric tons per year and accounting for 36% of the world’s supply. France, Germany, and Spain are the heaviest producers within the EU. Russia follows at 13% (19.4 million metric tons), then Australia at 10% (15.5 million metric tons). Canada, the United Kingdom, Ukraine, Argentina, Turkey, Kazakhstan, and the United States round out the top ten, each contributing between 2% and 6% of global output.
The United States grows about 3 million metric tons annually, concentrated in the northern Great Plains. North Dakota is the leading state, where barley serves as both a feed grain and a major cash crop for the malting industry. Idaho, Montana, and Washington also contribute significant acreage.
Climate and Soil Conditions Barley Needs
Barley is a cool-season crop. Seeds germinate best between 12°C and 25°C (roughly 54°F to 77°F), though germination can happen at temperatures as low as 4°C (39°F). Seedlings establish most successfully when soil temperatures sit around 10°C to 15°C. Once soil temperatures climb past 40°C to 45°C, emergence drops sharply, which limits barley’s range in tropical lowlands.
The grain is notably flexible when it comes to soil. It performs well across a pH range of 6.0 to 8.5, meaning it handles everything from slightly acidic to moderately alkaline ground. It prefers well-drained soils and does best in cool, dry climates. In arid regions, at least one irrigation event is typically needed to get the crop established, but barley generally requires less water than wheat or corn, which is part of why it succeeds in semi-arid areas like parts of Australia, Kazakhstan, and the American West.
Spring Barley vs. Winter Barley
There are two main planting types, and where each one grows depends on how harsh the winters get. Spring barley is planted after the last frost and harvested in late summer. It’s the dominant type in regions with severe winters, like the northern U.S., Canada, Scandinavia, and Russia, where the crop wouldn’t survive in the ground over the cold months.
Winter barley goes into the ground in autumn and stays dormant through the cold season before resuming growth in spring. It’s more common in milder climates: the UK, much of Western Europe, and parts of the southeastern United States. Winter varieties often yield more because they have a longer growing season, but they need enough cold tolerance to survive freezing temperatures without being killed off.
Malting Barley vs. Feed Barley
What barley is grown for also shapes where it’s planted. Feed barley, used for livestock, is the more common type globally and is grown across nearly all barley-producing regions. Malting barley, which ends up in beer and whiskey production, commands a higher price but requires tighter quality standards, particularly for protein content and kernel uniformity.
In North Dakota, for example, barley’s economic value is tied far more to the malting industry than to feed use. Farmers in that region manage nitrogen fertilization carefully because too much protein makes barley unsuitable for malting. Similar malting-focused production happens in parts of Montana, the Canadian prairies, and across Northern Europe, where breweries and distilleries create steady demand. Australia’s barley exports also lean heavily toward malting quality, feeding Asian beer markets.
Extreme Elevations and Harsh Environments
No other major cereal crop matches barley’s altitude range. In Tibet, a highland variety called Qingke has been collected at elevations from 580 meters all the way up to 4,750 meters above sea level. That upper limit, roughly 15,580 feet, makes barley the highest-altitude grain crop on Earth. These Tibetan landraces have adapted over centuries to intense UV exposure, thin air, and short growing seasons.
Barley also grows at high elevations in the Andes and in Ethiopia’s highlands, where other grains struggle with the cold nights and poor soils. Its ability to mature quickly (some varieties need just 60 to 70 days) makes it one of the few reliable food crops in these environments.
Where Barley Originally Came From
Barley was one of the first crops humans ever domesticated. The oldest archaeological remains of cultivated barley date to about 8,500 B.C. and come from Neolithic sites in the Fertile Crescent, including Abu Hureyra in Syria and Jericho in the Jordan Valley. Genetic evidence published in the Proceedings of the National Academy of Sciences points to at least two separate domestication events: one in the Fertile Crescent and a second 1,500 to 3,000 kilometers farther east, likely in present-day Afghanistan or western Pakistan.
Wild barley, the ancestor of all cultivated varieties, still grows across a broad natural range stretching from the eastern Mediterranean through Central Asia to Kyrgyzstan. That wide native distribution helps explain why barley carries so much genetic diversity and why it adapts to such varied environments today.
How Climate Change Is Shifting Barley’s Range
Rising temperatures are already reshaping where barley can grow. A 2024 study modeling barley suitability in South America found that only about 6.6% of the continent’s territory is currently suitable for rain-fed barley cultivation, concentrated in temperate southern zones. Nearly 19% of the region is already too hot. Under the most severe warming projections, just 1.5% of South America’s land area would remain viable for barley farming.
The pattern is similar elsewhere. As growing seasons warm, barley cultivation is expected to shift poleward and to higher elevations. Regions in northern Canada, Scandinavia, and Russia that were previously too cold may become productive, while traditional growing areas closer to the equator face increasing heat stress and water scarcity. For now, barley’s tolerance for cool, dry conditions gives it an advantage over many crops, but that advantage narrows as temperatures climb.
