WORK OF 1903-4. 37 
May 2d. — Bright, beautiful amber color; decidedly gaseous; pours 
with beautiful bead, clear, pale amber; decidedly fruity bouquet; 
flavor slightly acid. Analysis on this date resulted as follows: 
Specific gravity 1. 001 
Solids grams per 100 cc. . 1. 83 
Total sugar do 35 
Alcohol do 5. 16 
Acid do 35 
Tannin do 042 
This yeast produced in this case a tine grade of effervescing cider, 
equal to the best French mousseux ciders. While the general char- 
acter of this cider is the same as that from yeast No. 73, cask 15, there 
is still a decided difference, which can not be readily defined in words. 
This difference would appear to be due to the character of the yeast 
used. 
Cask Experiment No. 14. 
Cask No. 14 is omitted from this report because the results are not 
of sufficient interest to warrant presentation. It was sown with yeast 
No. 71, a form isolated from wine lees secured by Mr. Alwood from 
Alsace, Germany. This yeast is a peculiar form, always growing in 
coagulated masses and leaving a very clear, bright liquor in the fer- 
mentation flasks, but in barrel tests it has in no case shown any valu- 
able characteristics. 
Cask Experiment No. 15. 
General notes the same as for test No. 12. Cask No. 15 was filled and 
sown on October 7, 1903, with 1 pint of culture of yeast No. 73. 
The origin of this yeast has been previously given under No. 2. 
NOTES.

October 25. — Temperature of must, 49.5° F. ; cider, cloudy; flavor 
good; specific gravity, 1.014. 
October 27. — Partial anal3 T sis on this date shows a specific gravity of 
1.013; alcohol 3.85 and sugar 2.42 grams per 100 cc of cider.
