REPORT. 
The committee are of the opinion that many of the samples submitted did 
not fairly represent the vineyards from which they were obtained, either because 
of very defective corking or because of the wine being bottled too soon after 
fermentation, or from other defective handling. Whatever may be the cause, it 
seemed unjust to pronounce any opinion upon the merits of wines which were 
plainly unfit for drinking. For this reason the committee do not express any 
other opinion (than just - remarked) upon a great majority of the samples sub- 
mitted to them. 
Of the white acid wines the committee selected only four which they deemed 
‘worthy of special notice. 
1. California hock (Perkins & Stern.) 1863. 
2. Sonoma hock ss 1862. 
3. Folsom hock os 1862. . 
4. White wine (Matt. Keller.) 
Of these four varieties they gave the preference to Keller’s white wine (No. 4,) 
while the hocks were of nearly equal quality, the Folsom being preferred. 
Of the sweet wines, the red Traminer(Bugby 1863,) and the Verdelho (Bugby
