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 43% equals about 1.08 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.

Old Grand Dad Background

Old Grand Dad is the database spelling for Old Grand-Dad Bourbon, a legacy bourbon brand listed in the Suntory Global Spirits corporate portfolio. The manufacturer metadata intentionally stops at parent-company level because the source used did not state a current legal producer. DUI Professional uses the row as a 1.5 fl oz bourbon profile at 43% ABV, and those stored values remain the BAC simulation inputs.

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 43% ABV contains 0.65 oz ethanol, equal to 1.08 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.
