I've heard the term Angus beef thrown around a lot, particular by fast food chains attempting to entice customers to by their burgers there. But is Angus beef really better than "regular" beef or is it just a bunch of smoke and mirrors? Sure it sounds pretty good and makes you feel like "man's man (or woman)" when you order it or just say it's name, but does this translate into superior quality or flavor?
As usual, my go to for information such as this is Wikipedia. Angus is derived from Aberdeen-Angus, which was the name of Scottish breed of cattle. Angus (or Blank Angus) is the most popular breed of beef cattle in America. Interestingly, Angus cattle are used strictly for meat, due to their natural marbling (fat located within the meat), but are also used for cross breeding purposes with other types of cattle in order to improve both marbling and milking ability. Why Angus cattle are not used for milk is not elaborated on unfortunately.
During 2003 and 2004, Fast food restaurants created a PR campaign for the purposes of promoting the supposed superior quality of beef from Angus cattle. In fact, there is a American Angus Association who's primary purpose is to promote the idea that Angus beef is better than all other beef. I won't get into the 10 characteristics that must be met to be considered Angus cattle, but you can check it for yourself at http://en.wikipedia.org/wiki/Angus_cattle if you are interested.
I think the main thing that can be taken from this is that there is not significant evidence that Angus beef is any better or worse that other beef. There is certainly a lot more marketing and PR muscle behind it, but not a whole lot of definitive statistics to to back it up. I say buy beef that looks fresh and has good marbling. If it happens to be Angus, that is fine, but I would not choose one over the other solely based on the name.
