When selecting their whiskey of choice for this fourth release, Leighton and Blender Dave McCabe combined innovation, tradition, and time-honoured craftsmanship by vatting together four special whiskeys, aged for a minimum of 29 years in ex-bourbon, sherry, and ruby port seasoned casks. The whiskeys were then married in a single outstanding Oloroso sherry butt from Jerez de la Frontera in Spain’s Andalusia region and left to mature for a further 15 months to bring an evolution of its characteristic flavours to the Redbreast experience. Having launched on world whiskey day only 914 bottles were made available.
