WORK OF 1903-4. 33 
bouquet not strong, but pleasant; flavor not very smooth, but good, 
clear; a fine acid; generally desirable; color, a pale amber shading to 
straw color. Analysis of this sample on this date gave the following 
results : 
Specific gravity 0. 998 
Total solids grams per 100 cc. „ 1. 73 
Total sugar do Trace. 
Alcohol do 6. 20 
Acid do 37 
Tannin do 046 
May 25. — First bottling (unfiltered): In bottle, bright like filtered 
goods; shows a slight amount of flocculent granules resting in the 
liquor; practically like filtered product as to gaseousness; color an 
opalescent, pale amber, shading to straw color. Bouquet weak and a 
mild, pleasant flavor; apparently the same as the filtered sample. A 
sample of the second bottling of this cider was sent to Doctor Wiley, 
who says, "No. 10 has a good flavor, but not quite so good as No. 9." 
The analysis made at the Bureau of Chemistry, Department of Agri- 
culture, is as follows: 
Grams per 100 cc. 
Sugar 0. 082 
Alcohol 6. 12 
Acid, as sulphuric 223 
Acid volatile, as acetic 037 
Cask Experiment No. 11. 
The general notes are the same as those on cask experiment No. 6. 
Cask No. 11 was sown with 1 pint of culture of } T east No. 97 on Sep- 
tember 30, 1903, the bung plugged with cotton, and later fitted with the 
ventilation apparatus. Yeast No. 97 was isolated at Blacksburg from 
a small preparation of must of Soulard crab. It has the peculiar char- 
acteristic of growing in test-tube cultures in colonies or coagulated 
masses, thus showing at all times a bright liquor. 
October 1. — Fermenting actively; heavy foam on must; air already 
driven out of cask; temperature of must, 66° F. 
October 2. — Fermentation progressing rapidly. 
October 3. — Fermenting more slowly. 
October 10. — Condition same as in test No. 6; specific gravity, 
1.012. Microscopic examination shows yeast to be abundant; cells 
large, round. 
October 20. — Same as test No. 6 as to quality; specific gravity, 
1.002. 
October 27. — Partial analysis showed a specific gravity of 1.002; 
alcohol 5.06 grams and sugar 0.28 gram per 100 cc of cider. 
October 28. — Racked as in case of test No. 6. 
6390— No". 88—04 3
