Grass-Fed vs Grain-Fed Beef: What's the Difference?
Grass-fed, grain-fed, organic, pasture-raised. What do the labels really mean, and does it make a difference to what ends up on your plate?
In this guide
Grass-fed. Pasture-raised. Organic. Grain-finished. Beef labels have become a language of their own, and it’s not always clear which words matter and which are just there to look good.
So let’s take them one at a time.
What does grass-fed mean?
Cattle are natural grazers. Grass-fed cattle spend their lives eating grass and forage, the diet their digestive systems evolved for. Pasture-raised means they live outdoors on pasture, rather than in sheds or feedlots.
What does grain-fed mean?
Grain-fed cattle are usually moved onto a diet of grain, such as corn or soya, for part of their lives, often in the final months. Grain fattens cattle quickly, which keeps costs down. It’s common in large-scale beef production, particularly in the United States.
Is there a nutritional difference?
Diet changes the meat. A widely cited review in the Nutrition Journal found that grass-fed beef tends to have a different fatty acid profile from grain-fed beef, including more omega-3 fatty acids and more conjugated linoleic acid (CLA). It also found higher levels of certain antioxidant precursors, such as those for vitamins A and E.
In other words, what the animal eats makes a real difference to what ends up on your plate, and in your mug. That’s why we only use grass-fed, pasture-raised beef.
Grass-fed vs grass-finished
You may also see "grass-finished". Some cattle are grass-fed for most of their lives, then moved onto grain for the final months to fatten up. Grass-finished means the animal ate grass and forage right to the end.
Does it affect flavour?
Many people find grass-fed beef has a deeper, more complex flavour, while grain-fed beef tends to be milder. In a slow-simmered bone broth, that depth really comes through.
Grass-fed vs organic: they’re not the same
This is the one that catches people out. Organic certification is about how a farm is run, against a specific set of standards, and it’s checked each year by a certifying body. Grass-fed is about what the animal eats.
Beef can be organic without being fully grass-fed, and it can be grass-fed without being certified organic.
That second point matters more than you might think. Certification costs money every single year, and many smaller, independent farms simply can’t justify it, even when they farm to very high standards. They raise their cattle on pasture, keep them well and see no need for routine antibiotics, but they don’t have the logo.
It’s the same reason small artisan makers often use better materials than big branded names: the quality is in how something is made, not just the badge on the front.
How we source
Our beef broths are made from grass-fed, pasture-raised cattle from independent farms. We’re not certified organic, and we’re comfortable saying so, because what matters to us is how the animals are raised and what goes into the pot. Every batch we make is tested, and our broths contain no fillers.
Questions to ask before you buy
- Is the beef grass-fed and pasture-raised?
- Were the cattle raised outdoors on pasture?
- Does the brand test its products?
- What else is in the pack besides the beef?
If a brand can’t answer those clearly, ask yourself why.
Questions people ask
Is grass-fed beef healthier?
Research suggests grass-fed beef has a more favourable fatty acid profile than grain-fed, including more omega-3 and CLA. It’s why we use grass-fed beef in our broths.
Is grass-fed the same as organic?
No. Organic is a certification for how a farm is run. Grass-fed describes the animal’s diet. A farm can be one without the other.
Why isn’t your beef certified organic?
Our beef comes from independent farms, and certification is a yearly cost many small farms can’t take on. They still raise grass-fed, pasture-raised cattle.
Grass-fed, slow-simmered
Both our beef broths are made from grass-fed, pasture-raised beef. Pure Beef gives you 9.6g of protein per tablespoon with a neutral flavour. Beef Marrow is the rich, award-winning one for sipping.
