Some people might call this as 'syubhah' (some sort of grey area). It is neither halal nor haram but most muslim will avoid it. One simple reason may be that the drink it being processed at the same factory they process the alcoholic drinks. Same goes with meat being process with the same factory with pork meat for example. Even though you slaughter the cow according to Islamic ritual, the process of packaging/delivery of the meat itself must also be taken into consideration.
