Did you know that not all Prime Rib is "Prime"?

When it comes to Beef, the word Prime can cause a bit of confusion. So, what does it mean that Marilu's Market sells Prime Grade Beef? And, isn't all Prime Rib Prime Grade?

The answer might surprise you! When beef is graded in Canada, there are 13 categories. The four highest quality categories are A, AA, AAA and Prime. In all four categories, the beef must have a firm, bright red ribeye muscle. Other criteria include firm, white external fat and muscling that is graded between good and excellent. But, if all four categories are the same, what's the difference between them?

The answer is marbling. Marbling describes the amount of visible fat streaks. As meat cooks, the fat streaks melt into the meat, keeping it moist and adding flavour and juiciness. The more marbling, the more tender and juicy your meat will be.

Starting with minimal marbling in Grade A beef, the amount increases in each grade until you reach the highest quality, Prime. Less than 2% of Canadian beef shows sufficient marbling to be called Prime Grade. At Marilu's, our butchers seek out the best Canadian Prime Beef to bring to our customers.

This grading system causes confusion when we talk about Prime Rib. Prime Rib is a specific cut of beef and comes in many grades. Not all Prime Rib is Prime Grade! For example, Prime Rib comes in A, AA, etc.
