You'd hope to find fine wine vintaging in a 30+ year old garage. From our Italian pizzeria days, may I present to you Ernest and Gallo Johannisberg Riesling, limited release vintage 1984.
When the professional organizer came last week, I discovered a case of champagne and riesling. I took two bottles of each and gave the rest to Habitat For Humanity, who were picking up other housewares. They were really picky about what they'd take (like no unpacked dishes) but the two guys were cool with the wines. There was probably a blow out party at Habitat Gardena that night.
Ok at this second, I am actually regretting that decision. My logic was that we only had crappy wine at Numero Uno, so old crappy wine might be really gross.
However it is the only edible thing I've found so far. I'll let you know how the tasting goes.
