There are these things that alcohol brewers and coffee people use to add nitrogen to their coffee.
Nitrogenated drinks (e.g. nitro cold brew) give a nicer head and go down much smoother. It's usually a manual doo-hickey, and it use standard NO2 cartridges. One example is NitroPress, I don't know anything about the company, I think the general technique is neat and I'm sure there's a half-decent company somewhere. On amzn there were some around USD 100.
That does sound cool and would be neat for coffee but not sure would work for what im looking for unfortunately. I also kind of want that now too though so thank you lol
Ah, hope you find something for your dad!
