Wine and all other intoxicating beverages is haram in this world because it is toxic (intoxicant) made from fermented foodstuffs. However the liquor mentioned in the quran is not the same.
people in Islam don't drink wine because the effects of wine is firstly harmful and secondly alcohol is addictive.Alcohol and prayer do not mix and liquor clouds the intellect. 'Allah' and the 'Quran' has forbidden alcohol as well.
