Beer bottle capacitors?

What is the average capacitance of a salt water beer bottle capacitor?

Extremely low, in the ones to tens of nano-farads. Conversely they're extremely cheap and high-voltage safe.
You can calculate it. Work out the area of the plates, work out the gap between them, find a relative permittivity for soda glass (meh, 4-ish) and

C= 8.8.×10−12 x 4 x Area/gap (watch your dimensions)
