Cider Pasteurizing Problem

[pdwhit]

Hi,
I recently read a great article from Pappers's Gallery about pasteurizing my cider after bottling to keep bottles from exploding from continued carbonation. I did this and it worked well, but now when I open a bottle there is some crusty stuff at the top of the bottle which used to be at the bottom. Not a big problem for me, but don’t know what others might think if I offered them a bottle of cider and saw that.
If anyone knows how to avoid this, I would really appreciate it.
Thanks,
Pete

Tell them that you're a home brewer and you bottle condition. It's vitamin B (I think?) and it's healthy for them and reduces hangovers.
