How to Measure Proof After Distillation
- 1). Clean the hydrometer with warm water and dry it. Once the hydrometer has been cleaned, only touch the area above the scale.
- 2). Fill the cylinder with spirits to be measured. Leave at least 2 inches at the top of the cylinder; otherwise the liquid be displaced and overflow when the hydrometer is added.
- 3). Float the hydrometer carefully in the alcohol. The stronger the alcohol, the deeper the hydrometer sinks.
- 4). Get down to eye level with the hydrometer's scale for the most accurate reading.
- 5). Read the hydrometer measurement, without removing it, where the surface of the alcohol crosses the scale.
- 6). Clean the hydrometer with warm water after use.
