Clint Howard is reprising his role from Barb Wire (1996) in the reenacted version shown at the movie premier.
"Butchie" Peraino says he marinates cherries in Vodka and Fernet Branca. Fernet is a liquor (40-45% alcohol). Although made in Italy, 75% of its consumption is in Argentina. And although there are many brands, Argentinians drink Branca almost exclusively.
Peraino's pronunciation of Fernet ("fer-net") is accurate because it's Italian (Ususally miss pronounced as "fer-nay").
