There is. You can get a graduated tube from eaa or make one yourself. You
add water to the lower line, gas to the upper line and shake for 30 seconds.
After the water settles down to the bottom, you check to see if the line is
in the same place. If it's higher, you have alcohol. The EAA tube will tell
you the precentage.

Thought there was some kind of easy test you could do by adding water
to a sample of your fuel.
