Garrison Brothers Ranch Reserve Oloroso Sherry Cask Finished Single Barrel Cask Strength Bourbon Whiskey
Garrison Brothers Ranch Reserve Oloroso Sherry Cask Finished Single Barrel Cask Strength Bourbon Whiskey is the dry, savory counterpart to its PX sibling — one of 13 Oloroso barrels held back from the Ranch Reserve blending floor and bottled on its own at full proof. The Texas straight bourbon ages four years in toasted and charred new white American oak in the Texas Hill Country heat, then four more years in first-fill Oloroso sherry casks from Jerez, Spain: eight years in total. Bottled at cask strength, with proof varying by barrel from 124.6 to 136.7, in a 750mL bottle, hand-selected by Master Distiller Donnis Todd. It is available to order online at Del Mesa Liquor.

The Savory Side of the Ranch Reserve
Where Pedro Ximénez casks push Garrison Brothers bourbon toward dark sweetness, Oloroso — aged oxidatively, dry and nutty by tradition — sharpens and defines it. When Master Distiller Donnis Todd blended the Ranch Reserve releases, 13 Oloroso barrels stood apart with the depth and structure he looks for in a true standout, and they were bottled exactly as they came out of the barrel for the October 2026 single barrel release. Explore the rest of the bourbon whiskey range and the broader American whiskey shelf at Del Mesa to compare the two sherry traditions side by side.
Tasting Notes
Bold and structured: roasted pecan, walnut and baking spice over charred oak and the leathery depth Texas heat pulls from new barrels. The palate layers tobacco, dried fig and dark cocoa with a dry, elegant sherry character that lifts the oak rather than sweetening it. The finish is long, nutty and contemplative, carrying barrel-proof intensity and a savory spice that keeps evolving in the glass.
How to Enjoy
Built for slow sipping: pour neat and let the cask strength settle for a few minutes before the first taste. A splash of water opens the walnut and baking spice and takes the edge off the proof. It pairs naturally with aged cheeses, roasted nuts or a medium-bodied cigar. For more cask-finished one-offs, browse our whisky collection and gift sets.
Frequently Asked Questions
Why does the proof vary?
Each bottle is drawn from one barrel at its natural cask strength, never proofed down. The 13 Oloroso single barrels ranged from 124.6 to 136.7 proof; the exact proof of your barrel is printed on its label.
What is an Oloroso sherry cask finish?
Oloroso is a dry, oxidatively aged sherry from Jerez, Spain, known for walnut, tobacco and savory depth. Four years in first-fill Oloroso casks gives this bourbon a nutty, structured finish rather than a sweet one.
How does this differ from the regular Ranch Reserve Oloroso release?
The standard Ranch Reserve Oloroso bottling blends many barrels at 110 proof. These are the 13 standout barrels from the same production lot, bottled individually at cask strength.
