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

Current TA (g/L)

Measured titratable acidity as tartaric.

Target TA (g/L)

Desired titratable acidity as tartaric.

Volume (L)

Volume of must or wine to treat.

Calculate the tartaric acid grams needed to raise must or wine titratable acidity to the target. 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]

Tartaric acid (g)

Tartaric acid to dissolve into the lot.

• 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.

• TA Titration Volume to g/L Calculator

  Convert a sodium hydroxide titration volume to titratable acidity in grams per liter expressed as tartaric acid.

• Calcium Carbonate Dose Calculator

  Estimate calcium carbonate mass from wine volume and intended titratable-acidity reduction using 0.67 grams CaCO3 per liter for each 1 g/L reduction; confirm treatment limits and results with trials and analysis.

• Chaptalization Sugar Requirement Calculator

  Estimate sucrose needed to raise must from measured Brix to a target potential alcohol using 0.59% potential ABV per °Bx and 10 g/L sugar per added °Bx; volume change and non-sugar extract are ignored.
