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

Gelatin rate (g/hL)

Gelatin per hectoliter of wine.

Silica pairing (mL/g)

Milliliters of the selected silica product per gram of gelatin.

Volume (hL)

Wine volume to treat.

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. 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]

Gelatin (g)

Gelatin dissolved warm before the silica addition.

Silica gel (mL)

Silica gel dispersion added after the gelatin.

• 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.

• 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.

• Ascorbic Acid Complement Dose Calculator

  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.

• 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.
