I take it you are not familiar with Miller Draft or any of the other American Draft bottled beers then. Shame - you are missing out on some good bottled beers.
I also understand Guinness has recently replaced the widget system from their bottled "draught" beer with a coating of cellulose fibers on the inside of the bottle. Statements indicate a new development in bottling technology enables the mixture of nitrogen and carbon dioxide to be present in the beer without using a widget, making it as Guinness says, "more drinkable" from the bottle.
