I have a Vinator and sanitize my bottles with it. The neck is wider than the wine bottles so it slips past the stops. I made a washer and put that on there as a platform. What do other people do?
Unless they've redesigned it since I bought mine, 've never had an issue with beer or wine bottles...the bottle lip still pushes down on the trigger area. Keep pushing down and it squits just fine...but if it works for you.
I had the same problem with my 500ML PET bottles. Since I don't put it on top of my bottle tree, I use the red adapter as the filler piece instead - works great.
It just occurred to me, if this is a fairly common issue now, perhaps you should post a pic of your mod... In fact if you should consider putting it in my bottling tips thread, since a lot of new bottlers look at it, they might freak out when their vinator won't seem to work.
