There's a big bottle rack in the corner of the garage. I'd assumed everything on it was home brew (and disgusting) but my sister went through it at the weekend and found several bottles of "real" wine my parents had stashed away and forgotten. I opened one of them yesterday. It was a Cotes du Roussillon- vintage 1990. Ailz and my mother liked it well enough but I thought it tasted of nothing very much- watered down vinegar perhaps.
