Bill- I'm not really sure. I've been buying Stefania wines from the early days, but that's only about 4 or 5 years. I have yet to experience one shutting down, but the time frame might not be long enough to know. Right now Stefania occupies about 8.5% of my cellar, my #1 producer in terms of number of bottles. Because of that I don't hesitate to drink them young. I don't think there's anything wrong with drinking one now even if you only have 3.
