I bought the plastic ones...it seems after about a thousand bottles, the knuckles go and you start getting mis-caps. Most upsetting.
I visited Mike in the Rabbit's Foot Meadery in California last year. It's run by an Irish guy who was insanely proud of his new 2000-bottles-an-hour an our bottling machine (I suppose I would be, if I've just blown 50k on it).
The company who delivered it called around the next morning to show him how to use the computer interface on the front of it. Mike had already re-programmed it to look like the computers in Star Trek by then.
Is there a bottling solution in between the two ?
