As regards the questions you asked: Under no circumstances should Bahá'ís drink. It is so unambiguously forbidden in the Tablets of Bahá'u'lláh that there is no excuse for them even touching it in the form of a toast, or in a burning plum pudding; in fact, in any way.
There is no reason why Bahá'ís may not serve some alcoholic refreshment to their guests, if they feel sincerely that this will further their teaching work. If they can obtain their objectives without doing so, it would be better; but we don't want to give people the impression that we are peculiar in every way. (From a letter dated 3 March August 1957 written on behalf of Shoghi Effendi to an individual believer; The Compilation of Compilations, vol. II, Prohibition on Drinking Alcohol)
