Single-person pilot. Native blend proof calculates to 107.68 using Maker’s Mark Cask Strength at 112 proof. Prepare and evaluate separate native-proof and normalized-to-107-proof samples. Repeat both sessions from a fresh, independently measured preparation without consulting the first-session notes until the repeat results are recorded. Initial pilot rest condition: 7 days. This is a controlled test variable, not a universal marriage rule. For each normalized 15 mL evaluation sample, add 0.10 mL water to serve at approximately 107 proof. Physical preparation was confirmed by the user on 2026-09-01. The exact preparation clock time, actual vessel details, and Maker’s Mark batch or lot were not reported and remain open metadata.
User-prepared; actual vessel details not reported. Planned control: clean glass, at least 75 mL, tight inert-lined cap, minimal headspace.
Operational pilot. The confirmed four-bottle recipe and 60 mL volumes are loaded. Maker’s Mark Cask Strength is recorded at 112 proof, producing a calculated native blend proof of 107.68. Preparation Check should now read Ready.
Objective
This 107-proof custom blend introduces a mature, rustic complexity to a rich and velvety wheated foundation. Cloaked in an elegant aroma of dusty leather, seasoned oak, and cinnamon coffee cake, the palate seamlessly balances deeply layered dessert notes of buttery maple syrup and warm Amburana spice with a grounding mid-palate of charred oak, roasted pecans, and leathery tobacco. The result is a highly structured, elite-tier daily drinker that mirrors the body and sophisticated wood profile of a vintage, decades-old expression while retaining a unique, honeyed finish that punches far above its price tag.
Working Hypothesis
- Maker’s Mark Cask Strength — 34% / 20.4 mL: rich, velvety wheated foundation and bakery sweetness.
- Knob Creek Small Batch 9 Year — 30% / 18 mL: mature oak, roasted pecan, leather, and depth.
- Penelope Cooper Series Rio — 20% / 12 mL: honey, maple-dessert character, and Amburana spice.
- Benchmark Full Proof — 16% / 9.6 mL: proof, cinnamon, charred oak, tobacco, and structure.
Before Blending
Resting Checkpoint
Evaluation Protocol
- One person performs preparation, service, evaluation, and recordkeeping.
- Evaluate a native-proof sample and a separately normalized 107-proof sample.
- Conduct an independently prepared repeat of both proof treatments in a later session.
- For the repeat, remake the samples from the authoritative recipe and do not consult the initial sensory notes or rankings until the repeat records are complete.
- Stock may be consumed as necessary to complete the protocol.
Advancement Standard
A candidate advances only if it passes the minimum quality requirements, scores at least 4 of 5 for target fit, and remains in the leading group during an independently prepared repeat session.
Evaluation Sessions
Use the linked session records below. Check Evaluation Complete only after preparation details, sensory notes, quality decision, target-fit score, and leading-group status are locked.
Component Name | Order | Whiskey | Role | Volume (mL) | Percentage | Proof Used | Profile Proof | Proof Check | Batch / Lot | Rationale |
|---|---|---|---|---|---|---|---|---|---|---|
1 | Foundation | 20.4 | 112 | 112 | Provides the rich, velvety wheated foundation, bakery sweetness, and rounded body. Bottle proof recorded as 112. | |||||
2 | Oak / Depth | 18 | 100 | Supplies mature seasoned oak, roasted pecan, leather, caramel, and structural depth. | ||||||
3 | Modifier | 12 | 98 | 98 | Provides the honeyed dessert layer, cinnamon coffee-cake character, and warm Amburana spice. | |||||
4 | Spice / Structure | 9.6 | 125 | Adds proof, charred oak, cinnamon, tobacco, and a firmer structural backbone. |
