# If one drinks a drink before a meal one should not make a bracha achrona if one is going to drink during the meal. If one is not going to drink during the meal one should recite a bracha achrona.<ref>Mishna Brurah 174:25, Vezot Habracha (p. 82). The Magen Avraham 174:14 writes that according to
those who require a bracha rishona on drinks in a meal the drink before the meal is coming to exempt the bracha of the drinks in the meal and as such doesn't require a bracha achrona. Additionally, according to the Baal Hameor for any drink that one continues to drink in the meal it would not require a bracha achrona since it is considered like one long drinking. Vezot Habracha proves from the Shaar Hatziyun 174:38 that the main reason to accept the Magen Avraham is the first reason and not the second one.</ref> # However, wine and other liquors whet a person's appetite and don't require a bracha achrona before the meal.<Ref>Biur Halacha 174:6 s.v. v'afilu</ref>
# According to Ashkenazim, if a person ate [[Pat Haba Bekisnin]] such as cake before the meal since birkat hamazon might cover the [[Pat Haba Bekisnin]] no bracha achrona is recited on the cake before the meal.<ref>Mishna Brurah 176:2. Biur Halacha explains that since every definition of Pat Haba Bekisnin is questionable whether it is bread and if it is bread then certainly birkat hamazon covers it, one should not recite a bracha achrona on it before the meal.</ref> Some Ashkenazim argue to make a bracha.<ref>Rav Moshe Feinstein in Igrot Moshe 3:33 writes that cakes nowadays are so filled with a majority of sugar, oil, and sweeteners in comparison to the flour that they are certainly [[Pat Haba Bekisnin]]. If so, there is no question that they aren't bread and birkat hamazon doesn't exempt them.
Therefore, they deserve their own bracha before the meal.</ref> According to some Sephardim, a bracha achrona is made on [[Pat Haba Bekisnin]] before a meal.<ref>Vezot Habracha (p. 83) quoting Rav Mordechai Eliyahu</ref># On non-[[Pat Haba Bekisnin]] mezonot such as cooked mezonot one should recite a bracha achrona on that food before the meal unless one is going to eat that same food in the meal.<ref>Mishna Brurah 176:2</ref>
# If someone makes [[kiddush]] it certainly does not require a [[bracha achrona]] as it is exempted by the [[Birkat Hamazon]] either because of it is halachically linked to the meal or because it whets one's appetite.<ref>Mishna Brurah 272:35</ref>
# If someone makes [[havdalah]] over wine before [[melava malka]] and is going to drink more wine during the meal he doesn't need to make a bracha achrona.<ref>Shulchan Aruch Orach Chaim 174:4</ref> If someone isn't going to drink more wine during the meal he should recite a bracha achrona.<reF>Shulchan Aruch Orach Chaim 299:8</ref>
# If a person drinks wine before a meal one should not make an [[Al Hagefen]] afterwards because [[Birkat Hamazon]] might exempt it. Since it is a dispute it is proper to avoid this situation by either by drinking a melo lugmav (cheekful) and not a [[reviyit]], having intent when saying [[Birkat HaMazon]] that it should cover the wine, or have intent that one's Hagefen upon the wine before the meal should exempt the wine that one drinks in the middle of the middle as long as one does have wine in middle of the meal.<Ref>Vezot HaBracha (chap 9, p. 84) writes that because drinking wine before a meal involves a dispute one shouldn't make a bracha achrona. However, he quotes three pieces of advise from the poskim to avoid this situation. The first is to drink less than a [[reviyit]] in order not to become obligated in a bracha achrona. The next is to have in mind when making the [[Birkat HaMazon]] that it should exempt the wine one drank before the meal. Lastly, he advises that if one will drink wine in the middle of the meal that one has intent that the hagefen before the meal will exempt the wine in the meal. </ref>
# Regarding [[Kiddush]], according to Ashkenazim it's preferable to drink a Melo Lugmav and not a [[Reviyit]].<ref>Beiur Halacha 174:6 s.v. Vechen, Vezot HaBracha (chap 8, p 84)</ref> According to Sephardim, it's preferable to drink a [[Reviyit]] and have intent that the [[Birkat HaMazon]] should exempt the wine.<ref>Or Letzion (vol 2, 20:22)</ref>
