These parameters can be typed into WineCalc.<br /> WineCalc&#039;s calculations are based on the &quot;Sugar and Alcohol&quot;, &quot;Acids&quot;<br /> and &quot;Conversion Tables&quot; chapters of the Home Winemaking Book / Page.<br /> It uses several linear data-fits on the hydrometer table&#039;s data to<br /> perform the sugar calculations, together with a compensation for volume<br /> increase due to sugar addition, and the Pearson square for the blending<br /> calculations.<br /> It should make these calculations easier, since you don&#039;t need to<br /> perform them all by hand, and have them all in one program. Of course<br /> you should still understand what the principles of the calculations are.";
