There was a little more variation in the latter figures than in the 

 alcohol values, because in the sugar data there was apparently a 

 combination of variables in opposite directions. The 1.80 per cent

acid curves show that there was a slight decrease in total sugars 

 with decreasing amounts of water; but the percentage of fermentable 

 sugars increased at the same time, with the result that the actual 

 alcohol yield was practically constant. A larger number of cooks
