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 (g/hL)

Product dose specified per hectoliter for the selected culture.

Wine volume (hL)

Wine volume to inoculate.

Convert the manufacturer-specified mass rate for a particular malolactic culture into total product mass for the selected wine volume. 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]

Bacteria (g)

Malolactic culture to weigh out.

• 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.

• Isinglass Fining Dose Calculator

  Convert a bench-trial or supplier-specified isinglass rate into total product mass for the selected wine volume; it does not determine clarification performance.

• Metatartaric Acid Dose Calculator

  Convert a supplier-specified or treatment-plan metatartaric-acid rate into total product mass for the selected wine volume; the tool does not determine stability or persistence.

• 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.
