I'm clueless

[leilei]

I recently cleaned out my deceased Aunts basement. I found a few bottles of wine and I'm curious to know if they are drinkable or if they have any value. In the 40's and 50's , they used to grow grapes and make their own wine in the basement. It's always between 45-55 degrees down there. One is a bottle of "Nonno Pietro" vintage 1945.Produced and bottled by Dino Barengo, Ocampo, Ca. The label says only 984 bottles produced. The other is a bottle of Champagne. Lanson [red label] 1971 Brut. Any info would be appreciated. L
