DUI Professional Drink Profile
Harp
A public drink database profile for BAC simulation, drinking-pattern analysis, and litigation-support workflow review.

Reference volume

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.
12.00 oz at 4.55% equals about 0.91 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.

Harp Background
Harp is a verified beer profile associated with Guinness and Diageo's beer portfolio. The Guinness family includes stout, draught, and export-strength references, while related Irish beer brands such as Harp and Smithwick's have their own identity inside the same corporate portfolio. DUI Professional records that verified manufacturer context while the stored ABV and serving size drive BAC calculations.
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 12.00 oz reference serving at 4.55% ABV contains 0.55 oz ethanol, equal to 0.91 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.
