Beef sourcing
Why grass-fed beef?
Grass-fed beef comes from cattle raised primarily on pasture rather than finished on grain (corn, soy). The result is a leaner, more mineral-tasting beef with yellower fat (from beta-carotene in fresh grass), lower marbling, and a gamier, more "beefy" flavor profile. It is neither inherently better nor worse than grain-fed; the right pick depends on the dish and preference.
Background
In most North American beef production, cattle are raised on pasture for 12 to 18 months and then "finished" in feedlots on a high-energy grain diet for the last 3 to 6 months. This grain finishing is what builds the intramuscular marbling that drives USDA Prime / Choice grades. Grass-fed beef skips the grain finishing entirely; cattle remain on pasture until slaughter. Without the high-energy grain phase, intramuscular fat does not build to the same degree.
Flavor and texture differ. Grass-fed fat carries beta-carotene from the pasture, giving the fat a slight yellow tint compared to the white fat of grain-fed beef. The lean has a gamier, more mineral-rich flavor and is firmer in texture. Cooked properly (not over medium-rare, since the lower fat content makes overcooking more punishing), grass-fed beef delivers an excellent eating experience that is simply different from grain-fed. It is also typically leaner overall, which some buyers prefer for everyday cooking.

What to remember
Grass-fed = pasture-raised through finishing; no grain finishing phase
Lower marbling than grain-fed (often Choice or Select on USDA scale, rarely Prime)

Gamier, more mineral, more "beefy" flavor; firmer texture
More punishing to overcook than grain-fed because of the lower fat content
Common in Argentina (asado tradition), Australia, New Zealand, Ireland
