Distilling potable alcohol may be illegal in your jurisdiction. In some places in the US, it is illegal unless you render it impotable by adding repugnant flavors or poisons such as methanol. It may also be illegal to move the ethanol (even if it is rendered impotable) off your property. Check with local law enforcement before doing anything that might get you in trouble.
- Toxic in large quantities
- Ethanol does occur naturally as a biproduct of yeast growth.

from dilute ethanol
- Place dilute ethanol in alembic
- Place alembic in a double boiler
- Heat the boiler such that the water just barely steams
- Wait until the solution begins to cross to the receiver
- Check again to make sure the boiler is steaming but not boling
- Wait until either:
- the solution stops crossing to the receiver
- 95% of the solution has been transferred
- Your less dilute dilute ethanol is in the receiver.
- Re-estimate the percent complete
- until either
- the percent complete is between 75% and 99% (R=2)
- the "flare" from tossing a spoonful onto the flame looks "good enough"
- you are tired of doing this
- Get mass of dilute ethanol (M)
- Estimate concentration in percent-mass (D)
- Calculate mass of calcium oxide required to absorb the water = 3.2 * M * (1-D)
- Slowly add the calcium oxide to the ethanol
- Mix thoroughly
1 - (density of solution)
- Take a spoonful of material and put it on a cool non-flammable surface. Light it with a flame. If it burns away completely, it's nearly 100% ethanol. If it leaves a puddle of water, the amount of water left will give an indication of how much ethanol there is.
