Another experiment I made with the Concord satisfied me, without question, that the must of this grape will always gain by an addition of water and sugar. I pressed several casks of the pure juice, which, as the Concord had held its leaves and ripened its fruit very well, contained sugar enough to make a fair wine, namely, 75 deg.. This I generally pressed the day after gathering, and put into separate casks. I then took some must of the same weight, but to which I had added, to every 100 gallons, 50 gallons of water, in which I had diluted sugar until the water weighed 75 deg., or not quite two pounds of sugar to the gallon of water, pressed also after the expiration of the same time, and otherwise treated in the same manner. Both were treated exactly alike, racked at the same time; and the result is, that every one who tries the two wines, without knowing how they have been treated, prefers the gallized wine to the other--the pure juice of the grape. It is more delicate in flavor, has less acidity, and a more brilliant color than the first, the ungallized must. They are both excellent, but there is a difference in favor of the gallized wine. DR. GALL recommends grape sugar as the best to be used for the purpose. This is made from potato starch; but it is hard to obtain here, and I have found crushed loaf sugar answer every purpose. I think this sugar has the advantage over grape sugar, that it dissolves more readily, and can even be dissolved in cold water, thus simplifying the process very much. It will take about two pounds to the gallon of water to bring this up to 80 deg., which will make a wine of sufficient body. The average price of sugar was about 22 cents per pound, and the cost of thus producing an additional gallon of wine, counting in labor, interest on capital, etc., will be about 60 cents. When the wine can be sold at from $2 to $3 per gallon, the reader will easily perceive of what immense advantage this method is to the grape-grower, if he can thereby not only improve the quality, but also increase the quantity of the yield. The efforts made by the Commissioner of Patents, and the contributors to the annual reports from the Patent Office, to diffuse a general knowledge of this process, can therefore not be commended too highly. It will help much to bring into general use, among all classes, good, pure, native wines; and as soon as ever the poorer classes can obtain cheap agreeable wines, the use of bad whiskey and brandy will be abandoned more and more, and this nation will become a more temperate people.
