Today, I am reviewing a limited release from the D.C.-based company, Filibuster. Filibuster is mostly known for their “Dual Cask” series, which features a bourbon and a rye, both of which involved sourced whiskey finished in French Oak ex-wine casks (neither of which have I tried). However, Filibuster recently released Batch 1 of their limited release, “Triple Cask.”

Like the “Dual Cask” series, the “Triple Cask” is a sourced bourbon from an unnamed distillery and finished in our nation’s capital by Filibuster. The “triple cask” moniker refers to the Sherry casks (both Fino and Pedro Ximenez) that finish this bourbon. The sourced bourbon is about 5 years old, which puts the finished product at about 6-7 years, but there is no age statement on the bottle. Filibuster Triple Cask is a limited release bourbon, only being produced in small batches. It is bottled at cask strength, and Batch 1 clocks in at 117.47 proof (58.74% abv). Many thanks to my good friend, Bryan, for the sample on this one!

Let me just say at the outset, I have not yet tasted a whiskey that has evolved in the bottle quite like this one. When we first cracked this bottle, it was rough. The nose smelled mostly of charred rubber and sweaty leather shoes. The sherry influence came through a bit on the palate, but in funky, sulfuric manner. All throughout, the whiskey had a very harsh edge to it, almost in the vein of rubbing alcohol. The finish was long with burnt corn and wet moss notes. When we first opened this bottle, it was hard to drink.

However, after letting this bottle sit for about three weeks, with about one-fifth of the bottle consumed, it opened up quite a bit. Upon a re-taste, the nose was much more pleasant, with candied ginger, tar, burning wood, and some rubber notes. The palate still presented a type of funky sherry (reminiscent of Edradour), but also some macerated grapes and toasted coconut flavors. The finish was pleasant (the best part of this bourbon), presenting notes of sherry, mahogany, caramel, and butterscotch.

Overall, this whiskey was almost night and day. If I would not have gone back and re-tasted this whiskey, I would have given it a “D.” On the other hand, this whiskey would have gotten a “B-” from me if I had just sampled it halfway through the bottle, which is why I have decided to meet Filibuster Triple Cask somewhere in the middle. There are some very good finished bourbons on the market today (see Angel’s Envy), but I don’t think this belongs in that same category. My grade: C. Price: $60-70/750ml. For the price point, I’d be inclined to leave this one on the shelf unless you are extremely curious about a Sherry-finished bourbon.
