Responsa for Avodah Zarah 61:6
דתניא אחד הלוקח ואחד השוכר בית בחצירו של עובד כוכבים ומלאוהו יין ומפתח או חותם ביד ישראל ר"א מתיר וחכמים אוסרין
For it has been taught: If one buys or rents a house in a court of an idolater and stores wine in it, and the key or seal is in the charge of an Israelite: R. Eliezer permits it, but the Sages forbid it.
Teshuvot Maharam
The wine of a (Jewish) infidel or of a Karaite, who does not trust the teachings of the Rabbis, is yayin nesek (forbidden wine), for, although they are not idolators themselves, they do not guard their wine from being handled by Gentiles.
