Avodah Zarah 30: Wine, Beer, Snakes, and Intermarriage

Various types of wine, and when they are permitted -- mostly they are prohibited, but not necessarily so, for example, if something is prepared prior to the Jew ever appearing as a recipient of the wine, or ointment, or other derivative products. Plus, the distinction between a healing beverage and plain old regular beverage -- and whether they can be prepared on Shabbat. Plus, concerns about how making such beverages can go wrong. Also, the distinction between wine and beer - which is usually acceptable. And the concern about social mingling that can lead to intermarriage. Also, leaving liquid and beverages uncovered - and the risk of the snakes leaving venom in the water.
