Nope...never had any "bottling emergencies" when bottling. I count my caps out first, plus a few more to spare before I even start. Make sure I have priming sugar, take a grav reading to make sure beer is finished, etc. before I start racking...
Same with brewing, I've never run out of hops, or not had yeast or anything because I don't start until I have everything together.
It's called planning...and having a process. And not using glass I've never worried about shattering a carboy....
I got nothing...I don't know how folks have some of the problems they do, not equipment problems, or running out of propane, that can happen to anybody. But realizing they didn't crush their grain, or have all then hops the recipe calls for, or not having yeast. I'm not particualarly anal OR all that organized, but I have a recipe, and gather the materials into one place before I start heating water, if I didn't have my yeast or the hops, I would know pretty quick....
I just kinda make sure all the basic ducks are in a row before getting started.
