Shut Yein HaTov (“Responsa of Good Wine,” based on Song of Songs 7:10) is a work of responsa by Rav Yitzchak Nissim, the second Sephardic chief rabbi of the State of Israel. The first section was originally published in 1946, while Rav Nissim was working in business and before he was appointed chief rabbi. The second section was published more than 30 years later and addresses many questions that Rav Nissim received while serving as chief rabbi.
