Excerpt from Report of Work of the Experiment Station of the Hawaiian Sugar Planters' Association: Lysimeter Experiments

The washes for these determinations were set up at specific gravities varying from to with sugar contents of from to grams per 100 cc. The usual density 01 set ting up washes in rum distilleries is but molasses in coun tries making rum contain more sugars than, do those of Hawaii. Most yeasts are weakened in their action when the fermenting liquid begins to exceed six or seven per cent. Of alcohol, leav ing sugar unfermented The worts, therefore, must be made of such strength in sugars, that the final wash will not contain an excessive amount of alcohol. However, in late years yeasts have been cultivated that will withstand a much higher alcohol con tent than has usually been considered safe Thus, acording to Went and Geerligs,7 Saccharomyces vordermanmz. Can convert. The glucose in a solution of 18 to 19 per cent. Entirely 1nto alcohol. And the by-products. The advantages of such a procedure are: many. Yeast remains purer in concentrated mashes because the fermentation of the greater quantities of sugar which these mashes contain, yields more alcohol than in thinner mashes, and alcohol acts as a powerful poison towards schizomycetes and to dangerous varieties of yeast which are liable to work considerable damage.5 According to Maercker,5 a concentrated mash can be operated which will yield as high as 12 per cent. Of alcohol. An other series of fermentations was accordingly carried out, to see if stronger concentrations would produce as good results, the re sults of which are given in Table II.
