Be very, very wary of wine of dubious quality bought and rejected by a very cheap grandparent.
While I was emptying the dishwasher, my mom showed up in the kitchen with two bottles of wine she found sitting around somewhere in the house. Grandpa bought them sometime in the past, don't really know when - that alone was cause for concern. He wasn't known for choosing quality over saving a few dollars. So we opened one, and she poured a bit into a glass. My suspicions as to the wisdom of trying it were heightened when I saw how dark the 'white' wine was. My mom tried it...
After making some interesting faces, she ran off. A few moments later, I heard glass clinking together. This time, she showed up with a bottle of Asti my grandma from the other side of the family never got around to drinking. This time, I didn't hesitate to have some as well. Grandma had good taste. :)
