You are wrong in your description of the Rolling Rock label that "33" is the highest level in Freemasonry. The highest degree in Masonry is the third degree, the "Sublime Degree of a Master Mason". All others are adjunct degrees, requiring one to attain the MM degree before applying for those. Moreover, the 33rd degree is totally honorary, and is conferred only rarely on those Masons who exhibit the virtues of a Mason.
