2,384. The Wine of Monotheists
Maachalos Assuros 11:6
Regarding the children of non-Jewish servant women who were born in Jewish domains and circumcised but not yet immersed, the older ones render wine prohibited by touching it and the younger ones don’t.
Maachalos Assuros 11:7
Regarding a ger toshav – i.e., a “resident alien” who has accepted the seven Noachide laws upon himself – his wine is prohibited for drinking but permitted for benefit. We may leave wine in his care for a little while but not for a long time. Regarding non-Jews like Arabs who don’t worship idols, their wine is prohibited for drinking but permitted for benefit as per a ruling of the Geonim. As for those who worship idols, it is prohibited to benefit from their regular wine.
