An alcoholic festive beverage made by one dipping their unwashed penis in a vessel of mulled wine. The production process is notoriously dangerous, and experienced brewers are often incapable of producing a good brew by the end of their careers, due to being chemically castrated by hot wine. Usually comes with a salty taste accompanied with cheesy undertones and a sweaty aroma.
"Oh man I'm so gonna serve up my English teacher a glass of my finest smulled wine"
"Billy had been in the smulled wine business since youth, and as a result as no reproductive organs whatsoever"
