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

Alcohol concentration
43%
percent alcohol by volume
Reference volume

fluid ounces per full profile serving
Ethanol 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.
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.

Roku Japanese Gin Background
Roku Japanese Gin is a House of Suntory gin built around six Japanese botanicals layered onto a traditional gin botanical base. Official Suntory materials describe Roku as a Japanese craft gin, and the producer lineup distinguishes the 43% ABV export profile from the higher-strength domestic version. DUI Professional stores this row as a 1.5 fl oz serving at 43% ABV for product-specific BAC modeling.
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.
