Rittenhouse Rye is produced in the tradition of the classic Pennsylvania or "Monongahela" rye whiskeys, which are believed to have had a spicier and fruitier flavor profile. This style is said to be a high rye mashbill consisting of 80-100% rye grain. Ironically Rittenhouse is a low rye (50%) which is typical of the modern Kentucky rye mashbill.
This is a Bottled in Bond (BiB) rye. To be labelled BiB, the whiskey must be the product of one distillation season and one distiller at a single distillery, aged in a federally bonded warehouse under U.S. government supervision for at least four years, and it must be bottled at exactly 100 proof. Additionally, the BiB label must clearly identify the distillery where it was distilled and where it was bottled, if different.
