- Hydrometer
- An instrument that floats at different levels according to liquid density; temperature and alcohol affect interpretation during fermentation.
- Refractometer
- An instrument that measures how a sample bends light to estimate soluble solids; alcohol complicates sugar estimates after fermentation starts.
- Potential alcohol
- An estimate of the alcohol that fermentable sugar could produce, conditional on the conversion factor and fermentation outcome.
