This topic got me curious, so I googled a bit and found that some distilleries prohibit photography (and most electronics) because of the potential for an explosive atmosphere in the facility. It sounds a little screwy to me, but I don't know that much about how distilleries work and maybe they really do face enough alcohol fumes that sparks are a danger.

If that's the concern, they might be open to someone with a non-electronic camera...
