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.
