Yosef Karo, Translation:Shulchan Aruch/Yoreh Deah…
“ Contains 11 Seif1 A stone winepress that a gentile lined with pitch and then poured wine onto the pitch at the time of lining, or that an Yisrael lined and put wine in it and the gentile touched it while there's still liquid on the surface - needs cleaning. And if the gentile stepped in the lining cleaning is not enough, rather one must peel the pitch and then clean, or pour (hot water) without peeling, or leave it idle 12 months. ”
