I'm not a pro brewer, I'm just a lowly homebrewer and beer consumer. I love the can revolution, but I truly hate these six pack holders that cover the top of each can. I know the plastic rings I grew up with were an environmental disaster, but there has to be a better way than these can holders. There's no way to get a can loose without shaking it up and the volume of plastic required upsets my environmental sensibilities. End of rant, what options are available to the pro beer canner?
