2. Age
Age plays a big role in the flavor of a prime rib. It also plays a role in the price. An older prime rib will taste the best, but will also be the most expensive. It’s best to order the oldest option you can afford. Older prime ribs have aged longer.
Aging is a process that allows the enzymes in the meat to break down the muscles. This can make the meat more tender. During the aging process, bacteria will also start to grow on the meat and add flavor. The older the prime rib, the more developed and rich the flavor will be. That doesn’t mean a younger prime rib won’t be appetizing.
Older options are definitely more expensive than younger ones, but if you only cook prime rib occasionally or if you are preparing it for a special occasion, it’s better to splurge for the older option with the most flavor.
