Old wine

[polo]

Hello to all I am new to this so bear with me
I have a bottle of wine from the CRESTA
BLANCA Vineyard it is a "Souvenir Wine"
it is the "California SAUTERNE" and it looks
like a red wine..now I know that the vineyard
ceased in 1941 when sold to Schneley and in
1965 the winery was closed...is this a
valued collectiable or just pour it down the
drain
