Use this oenology calculation to document or plan a defined fermentation, blending, adjustment, stabilization, aging, packaging, sensory, or cellar operation from measured wine parameters.

Wine density (kg/L)

Measured or assumed wine density.

Target temperature (°C)

Holding temperature for tartrate precipitation.

Specific heat (kJ/kg·K)

Specific heat capacity used for the wine lot.

Starting temperature (°C)

Temperature of the lot before chilling.

Volume (L)

Volume of wine to chill.

Estimate the heat that must be removed to pull a wine lot down for cold stabilization from its mass and heat capacity; divide by the chiller's coefficient of performance to get electrical energy. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Heat removed (kWh)

Heat removed from the lot (Q = mcΔT, sensible heat only), expressed as kWh of thermal energy; divide by the chiller COP for the electrical energy consumed.

• Wine chemistry and microbiology depend on temperature, pH, alcohol, sugar, matrix, measurement method, microbial state, legal limits, product formulation, and bench-trial response. Generic doses and thresholds are not production instructions for every wine.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Confirm measurements with calibrated winery methods, run scaled bench trials, record additions and lot volumes, check local regulations and supplier specifications, and obtain professional laboratory advice for faults or stability risks.

• Alcohol Adjustment Water Blend Volume Calculator

  Size the watering-back addition that lowers a lot from its current alcohol to the target while conserving total ethanol.

• Casein Fining Dose Calculator

  Convert a bench-trial or treatment-plan casein rate in grams per hectoliter into total product mass for a wine lot; this calculator does not select an effective dose.

• Gelatin-Silica Gel Pairing Dose Calculator

  Convert caller-selected gelatin and silica-gel pairing rates into total product quantities for a wine lot; product concentration and treatment rates must come from trials or supplier instructions.
