49:5 If one did not set out to drink wine and it just ended up happening, or if he did not plan on drinking other beverages, he must recite a separate blessing over them. (Mishnah Brurah 174:3 disagrees in a case where the other drinks were present when he recited the bracha on the wine.) Regardless, there remains the issue of whether the other beverage should be covered by the final bracha he recites over the wine. In order to resolve the difficulty, one should eat a piece of fruit and recite the bracha of borei nefashos after it, intending to exempt the other beverages as well. (Mishnah Brurah 208:72 says that if he did not set out to drink wine and the other beverages were not present, then one must certainly recite the concluding blessing on the other drinks.)
49:6 If someone says kiddush over wine and he intends to drink liquor or coffee, there is a question as to whether or not they were covered by the bracaha over the wine. One should therefore specifically intend not to include them, then recite shehakol over something and have these beverages in mind.
