You can Google “energy vodka” or “energy beer” and find millions of links in each case. But you won’t find much by way of references to “energy” on TTB-regulated labels. TTB seems to be dead-set against allowing this term, almost without regard to the context. Edison Light Beer illustrates this. The product does not even contain caffeine or other stimulants. The label does, however, make a passing reference to “energy,” saying: “Edison brings new energy to light.” Or at least it did. TTB banished the term in this March 2007 temporary approval. By the time of this March 2008 replacement approval, Edison’s energy was dissipated without a trace.
