I can lager 8 kegs in my chest freezer. One reason.
This here is one reason I'd stick with kegging. Don't want to mess with bottling lagers, adding yeast at bottling, etc.
But carbonation isn't much of an issue with bottling is you know what you're doing. Neither is sanitizing bottles if you clean them out properly after you pour a beer. I don't think kegging is cheaper. The upfront cost is way greater, you still have to pay to replace lines, moving parts once in a while, deal with possible CO2 leaks or even liquid post leaks. I'm not arguing that bottling is better, I just think it's simpler. Sure it's more work on bottling day, but that's it, it's a one time deal. Kegging requires ongoing maintenance, which isn't necessarily bad or inconvenient.
Thanks for you input. I really enjoy kegging also, but enjoy the experience of opening a bottle of beer. I guess that's why I still do both.
