Showcasing Redbreast 12 Year Old's elegant, aromatic profile, the Tree Top Sour is a light and vibrant take – layered with a citrus combination of fresh lemon juice, sugar syrup and orange bitters. An Irish legacy, Redbreast’s signature 12 Year Old bottling boasts the complexity and distinctive qualities of pot still whiskey, matured in a combination of bourbon and sherry casks. The Tree Top Sour cocktail, in partnership with Redbreast Irish Whiskey, is exclusively available from 1 – 31 March, in celebration of St Patrick’s Day at Harvey Nichols Knightsbridge, Leeds, OXO, Edinburgh and Bristol, plus Beauty Bazaar, Harvey Nichols, Liverpool, as part of our cocktail of the month series.
