Ref. No. 985/4-140
In the name of Allah the most Gracious the most Merciful
The answer to your question is as follow:
Nowadays the alcohol used in edibles and medicines is generally made of vegetables, wheat, beans and coils etc. Such alcohol is pure and Halal. Similarlyaccording to our knowledge, the alcohol used to get the vanilla extract from its bean is not made of grapes, dates or raisins but it is made of vegetables thus it is pure and Halal. Nevertheless, if you ever come across an edible object that contains alcohol made of grapes etc. then it is impure and Haram even a drop of it.
And Allah knows best
