I don't have any big bottles but here's my largest. The Vermouth is only 12 1/2". The medicine is 10". So, come on I know some of you can do better than that.
I went to General George Shermans house in Ohio. The basement of his house was a glass blowing facory and it had all kinds of bottles and tools in there. I was practically drooling after i found out his house was a bottle making factory too lol. It was quite a treat though.
