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

Barrels

Barrels in the topping program.

Allowance per barrel (mL/wk)

Planning allowance of topping wine per barrel per week.

Weeks

Weeks between topping rounds.

Plan the topping wine needed for a barrel group over the coming interval. 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]

Topping volume (L)

Topping wine to keep ready for the interval.

• 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.

• 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.

• Egg White Fining Dose Calculator

  Convert a bench-trial egg-white rate per reference barrel into an exact equivalent and a rounded-up whole-egg count for the selected wine volume.
