Commentary for Avodah Zarah 59:5

שמואל ואבלט הוו יתבי אייתו לקמייהו חמרא מבשלא משכיה לידיה א"ל שמואל הרי אמרו יין מבושל אין בו משום יין נסך

Shmuel and Avlet were sitting together when boiled wine was brought up for them. [The latter] withdrew his hand. Shmuel said to him: Behold, they said that boiled wine is not to be suspected of idolatrous use.
