Brix very similarly to sucrose with respect to specific gravity as a function of concentration, or compounds which are present in small amounts (minerals, hop acids in wort, tannins, acids in must). In any case, even if °Bx are not representative of the exact amount of sugar in a must or fruit juice they can be used for comparison of relative sugar content. As specific gravity was the basis for the Balling, Brix and Plato tables, dissolved sugar content was originally estimated by measurement of specific gravity using a hydrometer or pycnometer. In modern times, hydrometers are still widely used, but
The Fox and the Grapes in the labyrinth of Versailles. He can therefore afford a thoughtful, moralising tone: But Benserade then adds another quatrain, speculating on the fox's mental processes; finally it admits that the grapes really were ripe but 'what cannot be had, you speak of badly'. One of La Fontaine's early illustrators was the artist Jean-Baptiste Oudry, who was also artistic director at both the Beauvais and the Gobelins tapestry works. In consequence of this a series based on La Fontaine's fables designed by Oudry was produced by them during the 1740s and included "The Fox and the Grapes". These stayed in production
