What Is Beef Marbling And Why?

You can’t help it. Your eyes light up at the sight of it and your taste buds start tingling, and it’s all because of that incredible piece of beef with more marbling than a Greek bathroom.

But what’s it all about and what does it mean for that piece of steak you’re about to eat?

What is marbling?

Marbling is the visible unsaturated (healthy) intramuscular fat that accumulates within the muscle and between the muscle fibre bundles. Visually, marbling is soft intramuscular (between the muscle fibre) fat made up of polyunsaturated, monounsaturated and saturated fats.

At chiller temperatures, marbled fat appears white and will become less obvious as the meat comes up to room temperature with unsaturated fats beginning to melt.

How does it happen?

Marbling is determined by both genetics and nutrition. Most are feedlot fed on carefully designed rations of straw for roughage, and grain for protein and carbohydrates. Cattle fed for Bear Paw Meats are ration developed over the years of feeding and eating beef. This includes: Locally sourced peas, barley, corn silage and straw.

What does it do to the beef?

The presence of marbling has an extremely positive effect on the eating quality of beef, in terms of tenderness, juiciness/moisture and flavour.

The fat makes the meat softer and easier to chew, as there is simply less muscle fibre and collagen per unit volume of meat. This decreases the amount of chewing required, leading to a more rapid breakdown of the food, and greater flavour release.

How does it change the flavour?

What’s that old anecdote? No fat, no flavour. With a higher fat content, perceived sweetness will increase, a higher oily mouth-coating will become more obvious, and the sour/acidity or acidic aftertaste and lingering aftertaste decreases.

When eating meat with a higher marble score, a more noticeable amount of meat juice (liquid fat and saliva) is produced, compared when eating lower marble score grade meats.

With a more rapid breakdown of the food, we experience a greater flavour release, and are more likely to get a higher peak flavour concentration.
