Peregrine
The first bird. Cognac and new American oak sit at its center, which give Peregrine its creamy, orchard fruit profile.
Our Highest Pursuit
An ongoing exploration in which each whisky has its own identity: one blending profile, matched to one cask regimen, explored in its entirety.

Hell Diver
A sherry study with PX Sherry at its center throughout. We took this profile as far as we believe it goes, and closed it with the 2026 release. There will not be a fourth.

Blend. Finish. Reblend.
The purpose of the High Altitude Collection is to explore specific blending profiles through cask finishing. In practice that is three steps, run in an order most producers would consider backwards. The notes beside each step are from Hell Diver 2026.

ONE
Blend
The blend is constructed around the cask regimen — built around what the components are asking for and what those casks can provide.
Variability between casks is enormous, even from the same bodega holding the same fill for the same length of time. We select ours in person to reduce that uncertainty and keep control of the finished whisky.
Most of what we need to know comes from a few minutes with a cask: the smell coming off the bunghole, whether the wood is still wet to the touch inside, and the taste of whatever remnant liquid is left in the bottom. We build the blend based on what those signals tell us.
HELL DIVER 2026
PX Sherry primary, with Oloroso Sherry in place of the Cognac casks used in the first two releases.
TWO
Finish
The blend goes into the casks as a blend, not as separate components. This matters more than it sounds. What comes out is not a set of individually finished whiskies. It is one whisky, divided across a number of casks, that comes back as that many slightly different versions of itself.
How long it stays is not fixed. We taste through the casks as they go and stop when the whisky is where we want it — generally a matter of months rather than years. Long enough for the cask to do its work, short enough that it does not take the whisky over.
Nothing is topped up or corrected while it sits. The casks do what they do, and we find out what we have when it is over.

Reblend
At this point most whisky would be bottled. Ours is not finished being blended.
Every cask is tasted on its own and treated as a component again. We build the final whisky out of the casks that belong in it and leave out the ones that do not. On some releases that means setting aside as much as half of what we finished.
The casks we leave out are rarely bad. They are the ones that pull the blend somewhere it should not go. This is the last blending decision we make, and it is the one that decides what the whisky actually is.
HELL DIVER 2026
[n] of [m] casks selected. 16 years, 124.1 proof. Cask strength, non-chill filtered, natural color, no additives. A single Oloroso cask from this release was bottled on its own at 125.2 proof and poured beside the finished blend at the Full Flight dinners.
