It’s a tricky question for a winemaker. You’ve made a dessert wine in the traditional style of a Port, but you have to name it something else. Unless the dark, sweet, fortified red wine was made in Portugal, the name Port cannot appear on its labeling or in the marketing, due to a 2006 law.
Rodney and Gayla Schatz, the winemakers at Peltier Station, found a clever and technical solution. They call their wine USB, like the hardware port on a computer. For extra nerd credit, the gnarled vine image on the bottle is composed of 0s and 1s, spelling out Peltier Station in binary code.
