I have a bunch of Liter bottles with the flip top on them. I've used them a couple times, and love them on Bottling day: they are much faster than 12oz bottles. However, I believe I am wearing out the little rubber grommets. Is there a easy place to pick these up? I haven't been able to find them online. Admittedly, I am a moron when it comes to doing research.
The bottles I have aren't actually grolsch bottles. They are brown.
