I am getting ready to bottle my first brew and have been soaking bottles to remove labels. As I was putting some on the drying rack today, I noticed some of the bottles had "No Refill" cast into them around the very bottom. I'm not sure exactly what brewery these came from because the labels are gone. However, I do have some fresh empties from Three Floyds and noticed they also have "No Refill" cast into them around the bottom, but the bottles I have from Pete's only have some small bumps cast into them around the bottom.
These are all pry off cap bottles from micro/craft breweries, but some have "no refill" cast into them and some do not. Is it safe to use the bottles with the "no refill" markings or do I need to source some bottles quickly? I will be bottling in 4-5 days and need to figure this out as quickly as possible.
