glycerol A sweet viscous by-product of fermentation. Glycerol content of a wine is increased by the use of high levels of sulphite in must preparation.
gravity The fractional part of the specific gravity (q.v.) when expressed to three decimal places. For example: SG=1.045 then gravity=45; SG= 0.998, gravity=998; SG=1.105, gravity=105.
