There’s a reason whiskey tastes so damn good: it’s spent a chunk of its life aging in immense wooden casks, allowing flavors to grow and harmonize over time. This one-liter version brings that process home, maturing moonshine – a.k.a. white whiskey – into a blend akin to bourbon. No matter what boozy elixir you fill it with, though, the cask’s charred interior will impart it with notes of smoke and oak distinct to your particular barrel. Each is handcrafted using American Oak reclaimed from barrels that once housed whiskeys you’ll find in any liquor store, and bound with steel bands to prevent leakage. They also each come with a storage tablet, which you should use to keep the wood fresh between batches; if you decide to switch liquors, though, you're going to need to invest in Thousand Oaks’ stronger cleaners.
