Previously thought to be discontinued, H-E-B’s Dr. B is back in action. H-E-B grocers can be found throughout Texas. Just as a warning, do NOT try to drink Dr. B if it has not been refrigerated. It is unbearable. However, it is at least palatable when chilled. Dr. B is of the fruity variety, and earns a two and a half Dr Pepper can rating.
According to one reputable Texan, HEB was founded by H.E. Butts, and therefore, Dr. B is often referred to by the nickname Dr. Butt.
