Ethanol 95 %: Wine Distilled, Rectified and Dried over Potash
Strong alcohol is wine distilled again and again. Andrew Ure (1839): simple redistillation over a water bath takes it to a specific gravity of 0.825, still about 11 % water; to go further, distil it over dry carbonate of potash, which holds back water. Stop at 95 % by volume, a hydrometer reading of about 0.81 at 20 °C.

Distil the wine
Distil the wine
Fill the alembic two thirds with wine and distil slowly through the cooled coil. Throw away the first small runnings (our choice). Collect until what comes over no longer tastes of spirit: these are the low wines.

Redistil over a water bath
Put the low wines in the retort, set it in a pot of water and heat the water, not the retort. Collect the spirit while the vapour stays under about 80 °C. Repeat until the hydrometer reads about 0.825, Ure's limit for plain redistillation.

Distil over the potash
Stir the dry potash into the spirit in the retort; it takes up water and settles as a heavy lower layer. Distil again from the water bath and check each portion with the hydrometer.

Keep it at 95 %
Keep the portions that read about 0.811 at 20 °C (95 % by volume) and bottle them stoppered; strong alcohol draws water from the air.

The redistillation, the 0.825 limit and the potash are Ure's; the quantities, the 80 °C guide and throwing away the first runnings are ours. Densities from Wikipedia. The vapour burns: no open flame near the receiver.
