Are the definitions for when there is “gmar melacha” (when it is a somewhat finished product) to be able to be considered wine that could have been offered by an idol worshipper to his/her idols, the same as for when wine is obligated to be tithed? If the strainer is put back in the top of the winepress, it forbids the wine in the winepress. The gemara tries to understand on what basis the wine in the strainer is forbidden as it hasn’t even reached the collection vat. Wine that is owned by a Jew – if the non-Jew touches it, is it forbidden to drink? Forbidden to benefit from it? What if the non-Jew touched it with one’s leg?
