Final gravity

After fermentation and distilling completed, I was unable to find final ABV because the hydrometer sank immediately to the bottom of testing tube, it didnt float at all. Even in straight tap water the hydrometer floated. Is the spirit okay to use? and if so How can I calculate the ABV to determine how much water to add to dilute to 40%

Here a copy of my answer to the same question you've already asked in the specialist questions:

In this case the alcohol content is to high for liquid level. In other words: the higher the alcohol content of the measured liquid, the deeper the hydrometer will sink in this liquid. Thus, the liquid level must be high enough to ensure the hydrometer can float without touching the bottom of the testing tube. Or rather: take a taller testing tube...

To calculate the needed amount of water for an appropriate dilution of your distillate, go to:
