An automated technique for the alcoholometric grade determination based upon measurement of dilution heat of ethanol in wine and appropriate reagent was tested. Interferences with wine other components was studied along with methods to minimize them. Two sets of determinations on more than 100 samples of various qualities (red wines, roses wines, white wines) and various geographical sources were performed and they were compared with the pycnometric reference technique. It is shown than this comparative study that for almost 95 p. 100 of the samples the alcoholometric grade can be determined with this automated technique with an accuracy better than 0,1 p. 100.
测试了一种基于测量葡萄酒中乙醇与合适试剂的稀释热来自动测定酒精度等级的技术。研究了葡萄酒中其他成分的干扰以及将其降至最低的方法。对来自不同产地（红葡萄酒、桃红葡萄酒、白葡萄酒）的100多个不同品质的样品进行了两组测定，并与比重瓶参考技术进行了比较。该对比研究表明，对于近95%的样品，使用这种自动技术可以测定酒精度等级，其准确度优于0.1%。
