Many of us at Bourbon Fest 2005 tasted a 21-year-old rye at Heaven Hill. That whiskey is now being prepared for market release as Rittenhouse Very Rare 21 Year Old Single Barrel Straight Rye Whiskey. Although it will be reduced to 100 proof (50% abv), it will not be chill-filtered.
The first release will consist of just 3,000 bottles (750 ml size) that will retail for between $125 and $150. It will be released in the United States (exact market list TBD), the UK and France.
It's important to note that this is not a one-time-only thing. Apparently they have a pipeline that will allow them to come out with new releases of the product annually.
This straight rye whiskey was made by Heaven Hill at their distillery in Bardstown that burned down in 1996. Heaven Hill continued to make rye at a time when there wasn't much demand for it, one of only a handful of distilleries that did.
