Monitor Ferment Progress with a Refractometer: Initial ☋rix (refractometer) Refractometer, these values must not have been calculated from oneĪlcohol (ethanol) has a higher refractive index than water, so a dry wine will usually give a refractometer reading in the range 5 to 15☋rix. The gravity measurement must beįrom a hydrometer, and the ☋rix measurement must be from a Provide accurate results in wines regardless of residual sugar.Īlcohol from Hydrometer & Refractometer: Specific GravityĬalculator uses a refractometer and hydrometer reading to ascertain theĪlcohol content of the sample. Note: This procedure, if performed carefully, will Temperature, however the temperatures, and calibration temperature of the This calculator includes hydrometer temperature correction so it is notĮssential to ensure the initial and final readings are made at the same Reading of 0.000), and a final reading is taken. Volume again with distilled water (or any water giving a hydrometer Is reduced to about half its initial volume, topped up to the initial This procedure involves taking a sample of known volume and Making predictions for similar musts (variety, region, condition etc).Īlcohol by Spirit Indication: Hydrometer calibration temp (☌)Ĭalculator will calculate alcohol by volume from the spirit indication The calculation gives the correct value, then use the calculator for Wines for which you know the final alcohol, and tweak the DSOS until Is hard to judge, but a suggestion is to use pre-ferment figures from The correction for DSOS is the the assumed gravity contributionįrom Dissolved Solids Other than Sugar. The calculation is based on the initial and final gravity. Reading, and then calculates the alcohol content.Īlcohol Prediction (pre-ferment): Current readingĭetails: This calculation is based on the method proposed by Duncan and Acton ( Progressive Winemaking). Of dissolved solids assuming that most of the solids are sucrose - itĭetails: A simple conversion between ☏ and ☌ and visa versa.ĭetails: This calcaultor converts between commonly used volume measurements.ĭetails: This calcaultor converts between commonly used mass measurements.ĭetails: This calcaultor converts between the commonly used measurements of vineyard area.ġ hectare (or square hectometre) = 10,000 square metres (a square 100m by 100m)Īlcohol by Ebulliometry: Calibration - pure water (☌)Ĭalculation corrects the ebulliometer reading based on the calibration Is not a measure of density, but is useful. Is an approximation, for more detailed alcohol prediction see the alcohol prediction calculator. Is not a measure of density, but it is useful. Some of these conversion are therefore based on expressionsĭerived from polynomial fits to experimental data sets. Physical property, and are often measured using different instruments. Perfect, for example specific gravity and ☋rix do not measure the same Gravity/Density/Sugar Conversions: Specific Gravityīetween various units of density.
