This is the specific gravity of as many different bottles of alcohol that I could find. This is particularly useful when layering drinks so that you can get a large enough SP different that each layer will float. These values will change with temperature. Chilling alcohol before attempting to layer it will help keep distinct layers. Also keep in mind this can be used as an indicator of flammability. Lower numbers tend to have higher proofs, and therefore are more inclined towards ignition. If you see any errors or know the specific gravity of anything not listed here, let me know and I will add it.
