Update, March 20, 2019: We discovered answers to outstanding questions we had about the PBR-branded whiskey in this Esquire Q&A with Matt Bruhn, the general manager of Pabst. We find a few of his comments strange—his assertion that people don't value aged rum, and some of his explanations of government labeling—but overall, Bruhn does give some more information about that 5-second-aging process. Give it a read if you want further details.
