Fill the burette of the acidimeter with the solution of NaOH and begin to titrate the milk in the flask.
GALL recommends that the quantity of acids be reduced to 6-1/2, or at most 7 thousandths of OTTO'S acidimeter, and the results have shown that this was about the right proportion; as the wines in which the acids were thus diluted were in favor with all consumers.
The next step in the improvement of wines was to determine the amount of acids the must contained, and this problem has also been successfully solved by the invention of the acidimeter:
But although by this improved acidimeter the quantity of acids could be ascertained with more nicety, there remained one defect, that in often turning the glass tube for mixing the fluids, some of the contents adhered to the thumb in closing its mouth.
I do not believe that the acidimeter can yet be obtained in the country, and we must import them direct from the manufacturers, DR.
As however, OTTO'S acidimeter shows about one eighth of the acids less than the must actually contains, and about as much acids combined with earths is removed during fermentation, DR.
a new acidimeter, invented by Mr. GEISLER, who also invented the new vaporimeter for the determination of the quantity of alcohol contained in wine.
"The acidimeter referred to was afterwards improved, by making the tube longer and more narrow, and dividing it into tenths of per cents, instead of fourths; thus dividing the whole above 0 into thousandths.
"The saccharometer and acidimeter, properly used, will give us the exact knowledge of what the must contains, and what it lacks; and we have the means at hand, by adding water, to reduce the acids to their proper proportion; and by adding sugar, to increase the amount of sugar the must should contain; in other words, we can change the poor must of indifferent seasons into the normal must of the best seasons in
