...it is clear that on all occasions officially sponsored by Bahá'í Institutions or where the host is acting as a representative of the Cause alcohol should not be served. In private homes or in the course of business or professional activity it is left to the conscience of Bahá'ís themselves whether they serve alcoholic drinks to non-Bahá'ís but the obligation is very strong to observe the prohibition enjoined by Bahá'u'lláh. (From a letter written by the Universal House of Justice to a National Spiritual Assembly dated 8 February 1968; The Compilation of Compilations, vol. II, Prohibition on Drinking Alcohol)
