It's the wrong end of the calendar but the Trader Joe's grocery chain offers an annual Vintage Ale at the end of the year; roughly between min-November and New Year's. The precise recipe differs from year to year but it's a very nice strong Belgian-style ale brewed for them by Quebec's Unibroue. I'd compare it to Rocheforte 8.

It's typically been priced at $5 for a 750ml bottle and after the holidays the price of the Vintage Ale drops quite a bit. In late January of this year I stocked up on 2007 Vintage Ale for $1.99 per bottle from my nearest Trader Joe's store. I haven't opened one in about three months but if past vintages and Unibroue's other beers are a guide this should age really nicely.
