I also loathe beer, and this troubled me at first too. Aunt Dee Dee did speculate that because the vision appeared to a man his favorite beverage was seen in the volcano. That is to say the drink that comes from the volcano is whatever we believers wish it to be, otherwise it would not be heaven if we were not satisfied with our drinks. So when you enter Heaven and approach the great Beer Volcano with your cup, it will change to the beverage that you crave most, your very own abroshia.
mmm Tequila here I come!
