Health advisory noted. Can't help myself, I'm a compulsive bare-footer. I'm sure I'll change that when I spill something hot on myself (although I'll probably cry due to loss of wort, not blisters on my toes!).
I had trouble with one of the Heineken bottles, but usually I can get them to cap OK. I use the normal wing capper, and occasionally, it just pops off to the side and doesn't work on them.
