How to Use This Calculator

Enter Wine A Percentage, Wine A Alcohol, and Wine A Titratable Acidity.
Set Wine B Percentage, Wine B Alcohol, and Wine B Titratable Acidity.
Review Blend Alcohol (% ABV) and Blend TA (g/L).
Use Wine A (normalized) (%) and Wine B (normalized) (%) to inform your decision.
Use the chart to visualize the results and explore different scenarios by adjusting inputs.

How the result changes with Wine A Alcohol

Wine A Alcohol	Blend Alcohol	Blend TA
6.5	9.82% ABV	5.88 g/L
10	11.92% ABV	5.88 g/L
15	14.92% ABV	5.88 g/L
19	17.32% ABV	5.88 g/L

What each input means

Wine A Percentage: Percentage of Wine A in the blend. The remaining portion will be Wine B. Percentages are auto-normalized to total 100%.
Wine A Alcohol: Alcohol by volume of Wine A. Measure with an ebulliometer or lab analysis for precision blending.
Wine A Titratable Acidity: Titratable acidity of Wine A in grams per liter (as tartaric acid equivalent).
Wine B Percentage: Percentage of Wine B in the blend. Adjust alongside Wine A to reach your desired ratio.
Wine B Alcohol: Alcohol by volume of Wine B.
Wine B Titratable Acidity: Titratable acidity of Wine B in grams per liter.
