Definitely. Though the oxidation seems different? I don't find cold brew to taste "stale" the way hot brewed coffee that's been stored overnight in the refrigerator does.

I have a bunch of kegging equipment that I don't use anymore because I've lost my taste for beer, and I keep wanting to see what happens if I use it to make cold brewed coffee under a bed of CO2.

Also, y'know, coffee on tap at home.

Won't the CO2 make the water acidic?

Nitrogen is better, but the equipment is more expensive and finicky. CO2 under just enough pressure to keep the oxygen out shouldn't dissolve into the liquid too much, though.

The downside is that you then couldn't use gas pressure to push the liquid through the tap line, but you can use gravity or a beer engine instead.
