I have made a lot of beer over the last 40 years. What distinguishes the swill most home brewers serve from commercial beer is the absence of yeast residue in the latter.
I used to dream of putting a piece of dry ice in each bottle before capping but it was unavailable where I was. I now carbonate water every day from a 20 lb bottle of CO2 but I no longer make beer.
