I have run a lot of different types of bottles, cans and even plastic through my USS-64.  Never tried a Grolsch bottle.  I would think those might be too wide to get through the vend gate into the vending area.  I home brew as well and just use 12 oz bottles with a manual crowner.  I know that is a lot more work though. Good luck and please post back if you find something or if the Grolsch bottles work.
