DUI Professional Drink Profile
Knob Creek 9 Year Bourbon

BAC Simulation Context
DUI Professional uses drink profiles as structured inputs for alcohol dose, absorption timing, and elimination modeling. This profile describes the concentration and reference serving volume used when a full drink is added to a simulation.
1.50 oz at 50% equals about 1.25 U.S. standard drinks because one U.S. standard drink contains 0.6 fl oz ethanol. Review how these values are used in BAC simulation software or compare it against the full drink database.

Knob Creek 9 Year Bourbon Background
Knob Creek 9 Year Bourbon is a 100 proof Kentucky straight bourbon in the Suntory Global Spirits portfolio. Official Knob Creek product information lists nine years of aging in white oak barrels and 100 proof, while Suntory identifies Knob Creek as one of its bourbon brands. DUI Professional stores a 1.5 fl oz, 50% ABV profile to model the product-specific ethanol dose.
Professional Use
- Compare drink assumptions during DUI and criminal-defense case review.
- Document beverage concentration and volume used in BAC simulation reports.
- Review drinking-pattern inputs with forensic toxicology and expert-witness workflows.
- Support training examples for alcohol absorption, elimination, and retrograde extrapolation.
Standard Drink Math
A U.S. standard drink uses 0.6 fl oz of pure ethanol. This profile's 1.50 oz reference serving at 50% ABV contains 0.75 oz ethanol, equal to 1.25 standard drinks.
That ethanol dose is the starting point for BAC simulation software; consumed fraction, timing, absorption, elimination, and body-composition assumptions are modeled separately. Compare other entries in the drink database or use the related profiles below.
