NA Beer

I would buy a couple of cases of Odouls, pour them into a keg, then add a pound each of crystal malt and biscuit malt in a grain bag to it, as well as some dry hops.  Steep for a day, pull the grain, then pull the dry hops after another couple of days.

Then it would taste like homebrew, and your dad will think you are a friggin’ genius.  :smiley:

I think you are going right direction.
You need to make very unfermentable low OG wort.

I made a 3.5% brown ale last fall using almost 50% specialty malts. I started with a surly bender clone recipe and just removed base malt to reduce abv. It worked out really well.
