Made using a crop of rhubarb originally grown in the kitchen garden of Buckingham Palace during the reign of Queen Victoria. The Warner's workplace is built on equality and diversity, while they make sure to look after the land and everything that sustains it; that includes how and where they source things, what resources they consume, and how they produce and package their gin. They even dedicate 1% of their total business revenue to environmental projects that make a real difference. The rhubarb juice is extracted using a traditional fruit press and blended with their Harrington Dry Gin to produce an alluring pink gin that is voluptuous on the palate with a sweet and tangy royal rhubarb explosion.
