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

Dose rate (mg/L)

Ascorbic acid specified per liter of wine.

Volume (L)

Volume of wine to treat.

Convert a user-selected ascorbic-acid treatment rate in milligrams per liter into total grams for a wine lot; determine the rate from an appropriate treatment plan rather than this arithmetic tool. 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]

Ascorbic acid (g)

Ascorbic acid to dissolve into the treated volume.

• 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.

• 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.

• Bentonite Fining Dose Calculator

  Convert a bench-trial or treatment-plan bentonite rate in grams per liter into kilograms of dry bentonite for the selected wine volume.

• CMC Stability Dose Calculator

  Convert a product specification or treatment-plan carboxymethylcellulose rate into total grams for the selected wine volume; it does not determine tartrate stability or select a dose.
