The Mishna in Masechet Ta'anit (26b) states that one may not eat meat or drink wine during the final meal before Tisha B'Ab. This is the only restriction on the consumption of meat mentioned by the Mishna or Gemara. On the level of strict Halacha, one is permitted to eat meat during the days preceding Tisha B'Ab, and even on the day before Tisha B'Ab, except during the last meal before the fast. However, customs were accepted among many Jewish communities to abstain from meat already earlier. The Shulhan Aruch (Orah Haim 551:9) brings three customs. Some refrain from eating meat already from after Shabbat Hazon (the Shabbat immediately preceding Tisha B'Ab); others observe this restriction throughout the Nine Days; and others follow the practice not to eat meat throughout the entire three-week from Shiba Asar Be'Tammuz through Tisha B'Ab. The Shulhan Aruch writes that everyone should follow his community's custom. Of course, this prohibition applies only on weekdays. According to all customs, one may eat meat on Shabbat, even the Shabbat before Tisha B'Ab. These customs developed for two reasons: 1) as part of our obligation to reduce our joy during this period when we are to reflect upon the destruction of the Bet Ha'mikdash; 2) the destruction of the Bet Ha'mikdash resulted in the discontinuation of the offering of sacrifices, such that G-d no longer has meat, as it were, so we, too, should not enjoy meat. The Gemara (Baba Batra 60b) states that there were those who, after the destruction of the Bet Ha'mikdash, decided to abstain from meat and wine, since there were no longer animal sacrifices or wine libations offered to G-d. However, they were told that by this logic, they should also refrain from grain products, because flour offerings (Menahot) could no longer be offered, and even from water, because the water libations (Nisuch Ha'mayim) were no longer offered. Quite obviously, we cannot live this way, and so we are not required to abstain from those products which were offered in the Bet Ha'mikdash. Nevertheless, as part of our effort to focus our attention on the tragedy of the Hurban (destruction) in the period leading to Tisha B'Ab, the custom developed to refrain from meat. Notably, not all communities accepted these restrictions. The Maggid Mishneh (Rav Vidal of Tolosa, Spain, late 14 th century) writes that in his area, the custom was to permit meat except on Ereb Tisha B'Ab. The Meiri (Provence, 1249-1315) writes that there was a practice among the exceptionally pious to refrain from meat on Ereb Tisha B'Ab, but even they did not refrain from meat before that day. Regardless, the Shulhan Aruch emphasizes that people whose communities observe the custom to refrain from meat during this period must adhere to the custom. Those who violate this practice are included in King Shlomo's stern warning in Kohelet (10:8), "U'foretz Geder Yishechehu Nahash" – "He who breaches a fence, a snake shall bite him." Even if a restriction that applies on the level of custom, and not as strict Halacha, is binding and must be obeyed. Nevertheless, since refraining from meat is required only by force of custom, there is greater room for leniency than there is when dealing with strict Halachic prohibitions. Thus, it has become accepted to permit meat when a Siyum celebration is held, and one should not ridicule those who rely on this leniency. In fact, it is told that Rav Moshe Feinstein (1895-1986) would conduct a Siyum every night during the Nine Days in the place where he would spend his summers, so that the people could eat meat. Since the prohibition to begin with is observed by force of custom, and not on the level of strict Halacha, the leniency of a Siyum is perfectly legitimate. In practice, when should we begin abstaining from meat? The accepted custom in our Syrian community is to begin refraining from eating meat from the second day of Ab. Although different opinions exist regarding the consumption of meat on Rosh Hodesh Ab, our custom follows the view of the Hida (Rav Haim Yosef David Azulai, 1724-1806) permitting the consumption of meat on this day. This was also the custom in Baghdad, as mentioned by the Ben Ish Hai (Rav Yosef Haim of Baghdad, 1833-1909), and this is the generally accepted custom among Sepharadim. One who does not know his family's custom can follow this practice and begin refraining from meat on the second day of Ab. The Kaf Ha'haim (Rav Yaakov Haim Sofer, Baghdad-Jerusalem, 1870-1939) cites an earlier source (Seder Ha'yom) as ruling that Torah scholars should follow the stringent practice of abstaining from meat already from Shiba Asar Be'Tammuz. However, recent Poskim – including Hacham Ovadia Yosef – ruled that since nowadays people are frailer than in the past, and Torah scholars need strength to continue their studies and their teaching, they should not observe this stringency. They should instead follow the more common custom to refrain from meat only after Rosh Hodesh Ab. One who wishes to eat a meat meal late in the day on Rosh Hodesh Ab should ensure not to recite Arbit early, before sundown. Once he recites Arbit, he in effect ends Rosh Hodesh, and begins the second day of Ab when eating meat is forbidden. One who wishes to recite Arbit early on Rosh Hodesh Ab must ensure to finish eating meat beforehand. The custom among the Yemenite Jewish community was to follow the Mishna's ruling, and permit eating meat except during the final meal before Tisha B'Ab. However, Hacham Ovadia Yosef ruled that once the Yemenites emigrated to Eretz Yisrael, they should follow the rulings of the Shulhan Aruch, and abstain from meat during the Nine Days. This prohibition applies even to meat that is not fresh, such as it if was canned or frozen. The Nehar Misrayim (Rav Aharon Ben Shimon, 1847-1928) records the custom among the Jewish community in Egypt to permit eating chicken during the Nine Days. As mentioned earlier, one of the reasons for the practice to refrain from meat is that we commemorate the loss of sacrificial meat in the Bet Ha'mikdash. Accordingly, Egyptian Jews permitted eating chicken, as chickens were not brought as sacrifices. This is the custom among Jews of Egyptian background even today. The Shulhan Aruch (551:10), however, explicitly includes chicken in his formulation of the custom to refrain from meat during the Nine Days. The Mishna Berura writes that one who is unable to eat dairy products (such as if he suffers from a milk allergy), and thus has limited options for food during the Nine Days, may eat chicken. If one needs to eat meat for health reasons, he should preferably eat chicken instead of beef, as there is greater room for leniency when it comes to chicken. Hacham Ovadia Yosef writes that if one removed the meat from a dish that consisted also of other food – such as if the meatballs were removed from the spaghetti – then, strictly speaking, the remaining food is permissible. Nevertheless, it is customary to be stringent in this regard and refrain from eating food which had been cooked together with meat. If parve food was prepared in a meat pot, the food may be eaten during the Nine Days, since it does not have meat in it. Even if the pot had been used with meat less than 24 hours before it was used to cook the parve food, the parve food may be eaten. This food contains the taste of meat, but not actual meat, and it is thus entirely permissible during the Nine Days. (In fact, according to the ruling of the Shulhan Aruch, this parve food may be eaten together with milk or yoghurt. The meat taste in this food has the status of "Noten Ta'am Bar Noten Ta'am" – a "second degree" taste, as the pot absorbed the taste of the meat, and the parve food then absorbed the taste from the pot. At this point, the taste does not forbid the food from being eaten with milk.) Hacham Ovadia Yosef allowed eating soup from bouillon cubes or bouillon powder during the Nine Days. It is permissible to eat fish during the Nine Days, though some have the custom not to eat fish during the final meal before Tisha B'Ab. One is allowed to eat synthetic meat during the Nine Days. Although one might have thought that this should be avoided due to the concern of Mar'it Ha'ayin – meaning, a person eating synthetic meat might be suspected of eating actual meat – we do not have the authority nowadays to enact new prohibitions out of this concern. If a person forgot that it was the Nine Days, or forgot about the restriction against eating meat, and he recited a Beracha over meat but then remembered that it is forbidden, he should take a bite of the meat, because otherwise his Beracha will have been recited in vain, in violation of the severe prohibition of Beracha Le'batala (reciting a blessing in vain). This is a far more grievous transgression than partaking of meat during the Nine Days – which, as we explained, is forbidden only by force of custom – and it is therefore preferable to take a bite of the meat so that the blessing will not have been recited in vain. (This resembles the case of a person who prepared to eat a dairy food within six hours of eating meat, and remembered after reciting the Beracha that he may not eat the dairy food. In that case, too, he should take a bite of the dairy food so the Beracha will not have been recited in vain. This applies also to someone who recited a Beracha to eat before praying in the morning, and then remembered that he may not eat because he had yet to pray. Even on fast days – except Yom Kippur, when eating is forbidden on the level of Torah law – if someone recited a Beracha over food and then remembered that eating is forbidden, he should take a small bite of the food.) If a person owns a meat restaurant, he is permitted to operate the restaurant during Nine Days, even in a Jewish community, where most or all of his customers are Jews. Given the leniencies that apply, such as permitting meat at a Siyum, and when necessary for health reasons, it is not for certain that the people coming to eat will be violating the custom to refrain from meat. As such, operating the restaurant does not violate the prohibition against causing people to sin. However, it is proper for the restaurant owner to place a visible sign at the entrance to the restaurant informing people of the widely-accepted custom to refrain from eating meat during the Nine Days. Just as many observe the custom to refrain from meat during the Nine Days, it is also customary to refrain from wine during this period. Although the practice in Jerusalem was to be lenient in this regard, and drink wine during the Nine Days, the practice among other Sephardic communities is to refrain from wine. This was also the custom in Arab Soba (Aleppo), as documented in the work Derech Eretz, and this is the practice in our community. There are two reasons for this custom. First, wine brings a feeling of joy, and during the month of Ab, until Tisha B'Ab, we are to reduce our joy and reflect on the destruction of the Bet Ha'mikdash. Secondly, we refrain from wine because we can no longer pour wine libations on the altar. Of course, wine – like meat – is permissible on Shabbat during the Nine Days. The restriction applies only on weekdays. It is permissible to drink other alcoholic beverages during the Nine Days, such as beer and whiskey. Cognac, however, is a type of wine, and is therefore forbidden. One should not drink grape juice during the Nine Days, but grape soda is allowed. Cakes that are baked with grape juice instead of water are allowed during the Nine Days unless the taste of grape juice is discernible, in which case one should refrain from these cakes. Vinegar made from wine is permitted for consumption during the Nine Days, because it has an acidic taste and does not bring enjoyment. Similarly, juice extracted from unripe, prematurely-harvested grapes is permissible. The Shulhan Aruch allows drinking wine at Habdala on Mosa'eh Shabbat during the Nine Days. The Rama (Rav Moshe Isserles, Cracow, 1530-1572), however, writes that according to Ashkenazic custom, the Habdala wine is given to a child to drink. The Shulhan Aruch also writes that one may drink during the Nine Days the cup of wine over which Birkat Ha'mazon is recited. When three or more men ate together, and they recite Birkat Ha'mazon with the introductory Zimun, it is customary for the one who leads the Zimun to hold a cup of wine during Birkat Ha'mazon which he then drinks after Birkat Ha'mazon, and according to the Shulhan Aruch, this cup may be drunk during the Nine Days. However, Hacham Ovadia Yosef rules that since nowadays people generally do not make a point of reciting Birkat Ha'mazon over a cup of wine, this is not permitted during the Nine Days.
