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

Appearance

Clarity and brilliance.

Color

Typicality and depth of color.

Aroma and bouquet

Aroma and bouquet intensity.

Volatile acidity

Freedom from vinegar taint.

Total acid

Balance of acidity.

Sugar

Balance of sweetness or dryness.

Body

Weight in the mouth.

Flavor

Varietal character on the palate.

Astringency

Tannin grip appropriateness.

General quality

Overall harmony of the wine.

Total the ten categories of the 20-point UC Davis wine scorecard and map the result to the commonly used superior, standard, below-standard, or unacceptable bands. 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]

Total points

Sum of the ten categories out of twenty.

Recommendation

One of superior, standard, below_standard, or unacceptable.

• 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.

• Blind Tasting Varietal Call Scorer

  Score exact varietal calls and aggregate partial credit against a caller-defined number of points per wine, then report both total points and percentage of the possible score.

• Wine Structural Age-Worthiness Score Calculator

  Average three user-assigned zero-to-ten ratings for acidity, body, and tannin into a structural aging score; it does not predict development, faults, closure performance, or drinking window.

• 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.
