Do you know what Athletic Brewing's techniques are? Have you tried their brews?
I heard the Experimental Brewing podcast and was interesting. I stopped by my local Total Wine to pick up some of their brews. They did not have any but they had an interesting mix of craft NA beers so I got a mixed 6 pack. 2 of them were disgusting (nasty corn-like flavor), 2 were just like grain teas with little flavor, a porter was okay...the only decent one I thought was Wellbeing Coffee Cream Brew (likely because it has lactose, coffee and spices). That was the only can of the 6 that I finished.
I skimmed through that stickied thread. It seems to be mostly one guy saying he created an "NA" beer that only gives him a slight buzz. Most of the "science" discussion says that this process does not work that well and the only post I see about somebody getting a test showed a very minor reduction in alcohol. I don't trust that thread enough to follow the process described.
Personally, I don't have a need to get beers below the 0.5% ABV threshold. I would be fine with a 1% or 2% beer that tasted decent. I brewed a 3% Porter that was okay. I mashed at 162F and had a really high FG (1.030). The downside is that it has more calories and carbs than it would have if it fermented to 5% ABV...which defeats half the purpose for me. I brewed a 3% Dark Mild a few years ago that was very enjoyable.
