Introduction
The Dry Weight/Volume Converter converts between dry weight (mass) and dry volume for a number of common winemaking additives. This calculator is intended mainly for home winemakers who don’t have accurate scales, and instead add ingredients on the basis of dry volumes (teaspoons, mL, etc.).
Input/Output Field Definitions
Additive – The additive for which the conversion is being made. Select from the long list of common (and not-so-common) additives.
Dry Weight – The dry weight (mass) of the additive. This field can be either an input field or an output field. If it is used as an input field, the dry volume is calculated from the entered value.
Dry Volume – The approximate dry volume of the additive. This field can be either an input field or an output field. If it is used as an input field, the dry weight (mass) is calculated from the entered value.
Calculation Details
All of the conversion factors are based on Jack Keller’s “Measuring Additives in Winemaking“, except for the sugar and sodium metabisulfite conversions which are based on my own measurements. Please be aware that these conversions are approximate.
