Although it is customary to refrain from meat and wine during the Nine Days, this restriction applies only on weekdays. On Shabbat, one may eat as much meat and wine as he wishes, without any restrictions. One may partake of meat during Se'uda Shelishit even the meal extends after sundown. And when Tisha B'Ab falls on Shabbat, and the fast is thus postponed until Sunday, there are no restrictions regarding the foods allowed during the final meal before the fast on Shabbat afternoon. One may have as lavish a meal as he wants, including meat and wine. Whereas generally several restrictions apply to the final meal eaten before Tisha B'Ab, these restrictions do not apply when Tisha B'Ab begins on Mosa'eh Shabbat. The question arises as to whether one may taste on Ereb Shabbat during the Nine Days a meat dish that is being prepared for Shabbat. Generally, it is proper to taste the Shabbat foods before Shabbat to ensure that they are flavorful. Rav Haim Vital (1542-1620) writes that this is a very important Misva, for just as cooks preparing food for a king must taste the food before it is served, this must be done for the honor of Shabbat, as well. It has been explained that this is the deep meaning of the passage in the Musaf prayer recited on Shabbat, "To'ameha Haim Zachu" – "Those who taste it have earned life." Is this permissible on Ereb Shabbat during the Nine Days, when partaking of meat is forbidden? Hacham Ovadia ruled that this is allowed, for two reasons. Firstly, he notes the Shulhan Aruch's ruling in a different context that if one tastes a small morsel of food to check its flavor, he does not recite a Beracha. This shows that tasting food does not qualify as an act of Halachic eating, and thus tasting a meat dish is allowed during the Nine Days. Secondly, Hacham Ovadia writes, the great value and importance of tasting the Shabbat foods overrides the custom to refrain from meat during the Nine Days. Some poskim ruled that one who tastes the meat dish on Ereb Shabbat must then remove it from his mouth without swallowing, but Hacham Ovadia maintained that the food may be swallowed, because of the two reasons mentioned above. Rav Yisrael Bitan writes that in conversation with Hacham Ovadia, the Hacham made it clear that this leniency applies only after Hasot (Halachic midday) on Friday, and that one may taste only an amount less than a Rebi'it of the meat dish. If meat was prepared for Shabbat during the Nine Days, and some of the meat is left over after Shabbat, Hacham Ovadia permits eating the leftovers, particularly if one eats the leftovers for Se'uda Rebi'it (the meal eaten after Shabbat, also known as "Melaveh Malka"), and especially if one normally eats meat during the Se'uda Rebi'it. Although meat is forbidden on weekdays during the Nine Days, nevertheless, meat left over from Shabbat is allowed. One may not intentionally cook more than he deems necessary for Shabbat so that he will have leftover meat for after Shabbat, but if he cooked food for Shabbat and some meat is left over, it may be eaten after Shabbat. There are several reasons given for this leniency. The Hida (Rav Haim Yosef David Azulai, 1724-1806) bases this Halacha on the Gemara's discussion regarding meat that Beneh Yisrael brought with them into Eretz Yisrael from the desert. During the forty years Beneh Yisrael spent in the desert, Shehita (slaughtering) was not required; they were allowed to kill an animal through any means and then partake of its meat. Once they crossed into Eretz Yisrael, this became forbidden, as Shehita was then required for meat to be permitted. The Gemara writes that if some leftover meat which was produced without Shehita was brought into Eretz Yisrael, then "Ho'il Ve'ishteri Ishteri" – since it was permissible, it remained permissible, even though meat produced this way was no longer allowed. Similarly, the Hida writes, since meat prepared for Shabbat was allowed on Shabbat, it remains permissible even after Shabbat. Although there is some discussion as to whether we may indeed permit food on the basis of the concept of "Ho'il Ve'ishteri Ishteri," when it comes to meat during the Nine Days, which is forbidden only by force of custom, there is room for leniency. Others explain that since this food was prepared for the purpose of a Misva, it is considered special and there is a Misva to eat it. Yet another explanation is the concern of "Bal Tash'hit" (wasting), as the food would otherwise have to be discarded. In one of Hacham Ovadia's earlier works (Kol Sinai), he wrote that we should not object to those who rely on this leniency and eat during the Nine Days meat that was left over from Shabbat – implying that this is not the optimal practice. However, Rav Yisrael Bitan notes that in his later works Hacham Ovadia writes that this is indeed permissible, and thus one may eat leftover meat after Shabbat without any reservations. Summary: Although we refrain from meat and wine during the Nine Days, there are no restrictions on what one may eat on Shabbat during the Nine Days; one may enjoy as much meat and wine as he wishes on Shabbat during the Nine Days. Before Shabbat, it is permissible – and in fact proper – to taste the Shabbat foods to ensure they are flavorful, even the meat dishes, but this should be done after midday on Friday, and only very small amounts may be tasted. If there is leftover meat from Shabbat, it may be eaten after Shabbat, preferably as part of the Se'uda Rebi'it meal after Shabbat. However, one may not intentionally prepare more meat than is needed for Shabbat so that he will have leftovers.
