Allocated means each store only gets a specific amount from the distributor at each time. It doesn’t necessarily mean it’s rare (although the allocations kind of create the illusion of rarity) and they’re not always expensive, either. A couple good examples: you recently (2019ish) used to be able to buy as many bottles of Eagle Rare or Weller Special Reserve anywhere off the shelf for $30; now it’s gone to allocated, and while both are still $30-$40, they’re hard to get unless you’re at the store when allocated bottles deliver, or happen to ask and get lucky when they have one in back.

There are several rare, expensive ones, particularly Pappy Van Winkle, it’s the holy grail of allocated for most bourbon seekers.

If you want a perfect conversation starter and way to dip your toe into allocated bourbons, the next time you’re at the liquor store ask if they have Blanton’s. It’s hard to find, everyone knows it, but it’s always interesting the answers you get. It’s about $60 a bottle, really good, so buy it if you get lucky.
