Today, Redbreast 27 Year Old Single Pot Still Irish Whiskey continues to pay homage to the legacy of Gilbey and its Irish origins. The whiskey is crafted from a marriage of malted and unmalted barley, which are milled and mashed before being triple-distilled through traditional copper-pot stills. The inclusions of unmalted barley in the whiskey's mashbill, along with the tradition of triple distillation, are uniquely Irish approaches to producing whiskey.

Following distillation, the whiskey is matured in a combination of American ex-bourbon oak and European oak casks that were previously used to mature Spanish Oloroso sherry. This expression then takes things to another level of complexity with the inclusion of Ruby Port Casks. After a 27-year slumber, the whiskey is bottled at cask strength without the use of chill filtration, resulting in an incredibly rich and complex dram.
