10 Year Old Bourbon
Why ten years in particular? There actually aren't that many ten year old bourbons (there are older and younger, but for some reason, not that many ten), but there are a few. The last two editions of Parker's Heritage Collection (an annual release that is different every year) are both ten years old (the 2010 is a wheated bourbon and the 2011 is finished in Cognac casks). These would both make excellent gifts and will likely run you $70-$80.
If you want something cheaper, Eagle Rare Single Barrel is a very good 10 year old that is more in the $25 range and is pretty easy to find.
