List of ITU-T V-series recommendations

The ITU-T V-Series Recommendations on Data communication over the telephone network specify the protocols that govern approved modem communication standards and interfaces.

Note: the bis and ter suffixes are ITU-T standard designators of successive iterations of a standard (bis and ter are derived from the Latin for "twice" and "thrice").

  • V44 (vodka)

    V44 is a brand of pure super premium wheat-vodka produced by the Bratislava-based company European Spirits and Liquor. Its name comes from numbers of sample variations. The basic vodka recipe is from a 1405 Baltic document, and is claimed to be the world’s oldest officially registered surviving vodka recipe. V44 is 100% unflavoured. Its taste and consistency is mainly achieved by using a special type of bio wheat, a proprietary fermentation process and by the cold gravity filtration processes. The production volume each year is limited to the available specified wheat. V44 Vodka is 44% alcohol and kosher certified.
