It would involve some understanding of the idea of distilling AFAIK, you'd find the temp that alcohol boils at and maintain that temp until as long as the internet says youre required to to remove 99% of the alcohol.
I would kind of say not to worry about it, because for me I can not even drink swill anymore, even getting drunk doesn't seem worth it when I have to drink macro beers. So, in this case what is the element you believe he wants? Taste of macro beer? Taste of delicious beer? Carbonated drink?
There are alternate answers to those. Don't take this as dismissive, I just am confused, because beer isn't just "beer" in a way.
