Grass Fed vs Grass Finished Beef: What Perth Buyers Actually Need to Know

"Grass fed" sounds clear enough. The animal eats grass. Done.

Except in Australian beef labelling, "grass fed" doesn't mean what most shoppers think it means. An animal can spend its last 60, 90, even 120 days in a feedlot eating grain — and still legally be sold to you as "grass fed beef." All it has to do is spend the rest of its life on pasture.

That gap between what the label says and what's actually on your plate is the whole reason "grass finished" is becoming the term people ask for.

If you live in Perth and you're paying a premium for what you think is grass fed beef, this is the bit worth understanding.

What "grass fed" actually means under Australian rules

The Pasture Fed Cattle Assurance System (PCAS) is the most rigorous voluntary standard in Australia. Under PCAS, a "grass fed" certification means the animal was raised on pasture and never finished on grain.

But here's the catch: PCAS is voluntary. Most beef sold as "grass fed" in Australian supermarkets and butchers isn't PCAS-certified. It's labelled grass fed because the animal spent most of its life on grass — which is technically true while still hiding a grain-finishing phase at the end.

That last 60–120 days matters enormously. It's when the animal puts on the fat that ends up in your steak. And the diet during that window changes everything: the omega-3 to omega-6 ratio, the levels of conjugated linoleic acid (CLA), the beta-carotene, the flavour. The animal you're eating is, in nutritional terms, mostly the animal it was for those last few months.

What "grass finished" means

"Grass finished" closes the loophole. It means the animal ate grass for its entire life — birth to slaughter — with no grain finishing, ever.

That's the standard for every cut of beef we sell at The Naked Butcher. When we say grass fed and grass finished, we mean it the strict way. The animals our farmers raise eat pasture from day one and they're never moved into a feedlot for finishing.

The result is beef that's measurably different from grain-finished alternatives:

• Higher levels of omega-3 fatty acids — the kind associated with cardiovascular and brain health.
• A better omega-3 to omega-6 ratio, which matters more than total omega-3 alone.
• More conjugated linoleic acid (CLA), linked in research to anti-inflammatory effects.
• Higher levels of beta-carotene and vitamin E, which is also why true grass finished beef fat has a yellower tint.
• Leaner cuts on average, with a different fat marbling pattern.

Whether those differences are life-changing for any individual eater is up to them. But the differences are real, they're measurable, and they're the reason "grass finished" carries a premium.

Where BOVAER fits in

There's a newer wrinkle worth knowing about: BOVAER, a methane-reducing feed additive that some Australian dairy and beef operations have started using. It's marketed as a sustainability tool, but it's another input going into the animal — and like any feed additive, it ends up shaping what's on your plate.

We don't use BOVAER anywhere in our supply chain. We don't use any feed additives. Our farmers feed cattle pasture, full stop. If you want to know exactly what your beef has been fed, that simplicity matters.

Why "from WA" makes a difference too

Beyond the grass-finishing question, sourcing matters. Beef labelled "Australian" can travel a long way before it reaches a Perth butcher counter. Beef sourced from local Western Australian farms doesn't.

Every cut of beef we sell — organic, grass fed grass finished, premium minced, scotch fillet, the lot — comes from WA farms we know and trust. Animals raised on WA pasture, processed locally, finished by us in Mundaring, delivered directly to homes across Perth and regional WA. Shorter supply chain, fewer hands in between, more accountability for what's actually in the meat.

So how do you check what you're buying?

A few quick tests next time you're shopping for beef in Perth:

Look for "grass finished" specifically. Not just "grass fed." The word matters.

Ask about feedlots. A butcher who knows the answer will tell you. A label that doesn't mention finishing usually means there was finishing.

Check the certification. PCAS, Australian Certified Organic, or a butcher who can name the farm. If the answer is vague, the meat probably is too.

Notice the fat colour. True grass finished beef has yellower fat from beta-carotene. Grain finished beef has whiter fat. It's not foolproof, but it's a clue.
