Beef sourcing
Why some beef is grass-fed
Grass-fed beef remains the historical norm in countries where pasture is abundant year-round and grain is expensive: Argentina, Uruguay, much of Australia, Ireland, New Zealand, parts of Brazil. The shift to grain-finished beef happened in the US during the 20th century to accelerate finishing and increase marbling, and in Japan with the rise of intensive Wagyu production. Whether a country produces grass-fed or grain-fed beef predominantly is more about climate, land use, and taste tradition than any quality verdict.
Background
In Argentina, the Pampas grasslands support year-round pasture grazing, making grass-finished beef both economically natural and culturally embedded in the asado tradition. The same is true for Uruguay, the south of Brazil, much of Australia's eastern grasslands, Ireland's wet temperate climate, and New Zealand's north and south islands. In these regions, grass-finishing produces excellent beef at lower cost than grain-finishing would, and the local taste tradition celebrates the leaner, more mineral profile that grass-fed delivers.
In contrast, the US Midwest produces enormous corn surpluses that make grain finishing economical and dramatically increase intramuscular marbling, which feeds the steakhouse-grade demand and the USDA Prime / Choice market. Japanese Wagyu production goes even further, with intensive grain-finishing for 28 to 36 months producing the extreme BMS marbling that defines the breed. Both systems work, both produce excellent beef, but they target different flavor profiles and different markets.

Key points
What to remember
Grass-fed predominant: Argentina, Uruguay, most of Australia, Ireland, New Zealand, parts of Brazil
Grain-finished predominant: USA, Japan (intensive Wagyu), much of Canada
Grass-fed = lower marbling, gamier flavor, yellower fat (beta-carotene), leaner profile
Grain-finished = higher marbling, beefier-rich flavor, white fat
Climate and pasture availability drive much of the regional difference, not arbitrary choice
Argentine asado, Australian BBQ, and Irish steakhouse traditions all celebrate grass-fed
