A really good steak begins with really good meat properly hung and aged. The French fail to grasp this concept. In all my years travelling around the country, working and living there I only had two good ones. But to be fair I rarely ever try one as I don't want to waste my money and/or be disappointed.
As a farmers son, (many years ago) I personally believe that Beef does not need to be hung too long IF it was aged on the hoof.
In other words, killed later in life. The same goes for Sheep.
