Grass fed beef comes from cattle that eat pasture for their whole lives, while grain fed beef comes from cattle finished on a grain ration in a feedlot, and the longer they stay on grain the more marbling and fat they build.
Grass fed eats leaner and beefier, and long-fed grain beef eats softer and milder. The nutrition gap is smaller than most people think.
Cost Cut Meats sells only grass-fed beef, and the full grass-fed beef range covers AMG 100% grass-fed Black Angus, Southern Ranges grass-fed and finished Angus, and Roam grass-fed Wagyu. Grain fed beef is not currently stocked.
Grass fed vs grain fed beef at a glance
In short, grass fed beef is leaner with a firmer, beefier eat, while grain fed beef becomes more marbled, milder and softer the longer it stays on feed.
| Factor | Grass fed | Grain fed |
|---|---|---|
| Diet | Pasture for life, finished on grass | Pasture first, then a grain-based ration in a feedlot |
| Time on grain | None | From a 35-day minimum for certified Grain Fed Finished to 300 days or more for some Wagyu |
| Marbling | Usually lighter | Similar when short fed, higher with long feeding |
| Flavour | Robust, beefy, slightly mineral | Milder, sweeter, buttery |
| Texture | Firmer | Softer |
| Fat colour | Often more yellow | Usually whiter |
| Nutrition | Omega-3 levels depend largely on pasture quality | Total fat rises with long grain feeding |
| At Cost Cut Meats | The whole range, from $26/kg (full box) | Not currently stocked |
| Best cooking | Medium-high heat, pull early, rest well | Handles a hard, fast sear |

What is grass fed beef?
Grass fed beef comes from cattle that graze pasture, and grass finished beef means they stay on pasture right up to processing, with no feedlot period.
A pasture diet usually produces leaner beef with a firmer texture and a deeper, more mineral flavour that shifts a little with season and region. The fat is often a touch more yellow.
Grass fed still supplies the larger share of Australian beef, but the gap has narrowed. MLA reported that grain fed cattle made up a record 47% of cattle processed in 2022, against a 10-year average of 38%.
What is grain fed beef?
Grain fed beef comes from cattle that are raised on pasture and then finished on a grain-based ration, usually in an accredited feedlot.
According to MLA, Australian feedlots use feed-grade wheat, barley, sorghum and triticale, combined with ingredients such as lupins, cottonseed or canola by-products and hay, rather than the corn and soy common in the US. Grain feeding keeps supply consistent, lifts eating quality and builds marbling for markets that want it.
Time on feed varies widely. The Grain Fed Finished standard requires at least 35 days on a high-energy ration in an accredited feedlot, while long-fed programs run far longer.
Taste and texture: which is better?
Neither is better outright: grass fed tastes beefier and eats firmer, while long-fed grain beef tastes milder and softer.
If you love a full beef flavour and a satisfying bite, grass fed delivers it, especially in steaks and roasts where the character of the meat shines. If you prefer a softer, buttery steak, the extra marbling of long-fed grain beef is what you are after. Many keen cooks choose by the dish rather than picking a side for good.
Is grass fed beef healthier?
Omega-3 in Australian beef comes mostly from pasture, but trimmed grass fed beef and short-fed grain beef contain very similar total fat, so the health gap is modest.
MLA's nutrition guidance explains that cattle turn the omega-3 in grass into long chain omega-3s, so levels in Australian beef depend largely on pasture quality. The same page cites an Australian study that found very similar total fat in fully trimmed meat from grass fed and 80-day grain fed cattle, with total fat rising when cattle were grain fed for 150 to 200 days.
If leanness is your priority, choose grass fed and trim the visible fat. If flavour and tenderness matter most, the cut and marble score will make more difference than the feed type.
Does grain fed beef always have more marbling?
Not always: marbling builds the longer cattle stay on a rich diet, so short grain feeding changes little while long feeding adds a lot.
MLA notes that because most Australian grain feeding is short, there is often little difference in marbling between grass fed and grain fed retail beef. Long-fed grain beef and heavily marbled Wagyu are where the gap opens up, and that shows on the label as higher marble scores.
Marbling is only one input to eating quality, which is why Australia's grading system weighs it alongside factors such as animal age, pH and ageing when it grades a cut.
Is Wagyu grass fed or grain fed?
Wagyu can be either, and the Roam Wagyu sold by Cost Cut Meats is grass-fed.
Wagyu is a breed, and MLA explains that feed time matters more than breed for fat: Wagyu fed on grain for 300 days or more is highly marbled and higher in fat, while grass-fed Wagyu marbles at levels similar to other breeds on the same diet.
Our grass-fed Wagyu range comes from Roam, raised on Queensland and NSW pasture and MSA graded MB2 to MB3+. That puts it at the light to moderate end of the marble score scale, a step up from lean beef without the intensity of long-fed MB9+ Wagyu.
Is grass fed or grain fed beef more expensive?
There is no single answer, so compare the per-kilo price of the same cut at the same marble score rather than the feed label alone.
At Cost Cut Meats, grass-fed prices run from $26/kg for a whole grass-fed rump to $77/kg for Roam bone-in Wagyu ribeye steaks, both full box prices checked 18 October 2026. Single pieces cost $10/kg more and half boxes $5/kg more.
Because we do not stock grain fed beef, we cannot give a like-for-like grain fed price.
How to cook grass fed and grain fed beef
Cook lean grass fed beef with a little more care and well-marbled grain fed beef with confident high heat, because their fat levels respond differently.
Grass fed beef has less fat to protect it, so it cooks a little faster and dries out if pushed too far. Pull it off the heat 3 to 5C before your target and rest it well. Well-marbled grain fed beef has more fat to render, so it stands up to a hot sear that builds a deep crust.
Knowing how to rest beef matters for both, since resting lets the juices settle back through the cut.
Which should you buy?
Buy grass fed for a leaner, beefier steak and long-fed grain beef for the softest, most buttery eat.
For lean everyday cooking and bold beef flavour, choose grass-fed Angus. For more richness while staying with pasture-raised beef, step up to grass-fed Wagyu. Long-fed grain beef is the pick for maximum marbling, though it is not part of our range.
Conclusion
Grass fed and grain fed beef are both good, just different. Grass fed is leaner and beefier, while long-fed grain beef is softer and more marbled.
Every cut we sell is grass-fed, from everyday Angus to MB2 to MB3+ Wagyu, delivered chilled to every state and territory except the NT.
