The Beer Bottle Organ made by Peterson Tuners
The sound is produced by blowing air over the tops of real beer bottles. The bottles are filled or “tuned” using mineral oil, so it will not evaporate or change tunings during weather changes. It can be played with the organ keys, or by a MIDI device. The Bottle Organ concept was first developed in the early 1800’s
