wine/champagne value?

[bobby_b]

hi all,

i have just come across something in a box that my grandmother had given me. i was hoping someone could tell me what i have here.

i have a corked bottle of

"Excelsior Sec"
New York State Champagne

CALINY WINERIES
MONTAGE VINEYARDS CO.
HAMMONDSPORT, NY


the vintage on this bottle is 1929.

do you suppose she saved it for sentimental reasons? or did she save it because it was good? finally, i am a wine newbie. is this stuff drinkable??

thx!
