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)

Activated charcoal specified per hectoliter of wine.

Maximum rate (g/hL)

Maximum rate allowed by the applicable treatment plan.

Volume (hL)

Wine volume to treat.

Convert a selected activated-charcoal treatment rate into total mass and compare it with a caller-supplied product, trial, or regulatory limit. 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]

Charcoal (g)

Charcoal to prepare for the treated volume.

Within recommended cap

Whether the dose rate stays at or below the supplied maximum.

• 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.

• 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.

• 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.
