Since launching in March this year, the gin has gone viral and proved popular with both gin and beauty fans.
Now as part of the #InternationalGinandTonicDay celebrations, the entrepreneurial pair behind the unique gin have launched what they are dubbing the 'CollaGin mini'.
Each 5cl serving of the gin is described as "flawlessly smooth and impeccably fragrant", and consists of eleven delicate botanicals creating "warm, earthy licorice and floral notes of orris root" that are balanced by the "clean taste of juniper and the gentle tang of fresh oranges".
The creation of Camilla Brown and Liz Beswick, two Oxfordshire entrepreneurs, the gin is distilled and bottled in England and is available in 50cl, and now 5cl, bottles from www.collagin.co.uk and selected online retailers.
The pair say the gin is best served with tonic, a touch of vanilla bitters, and a slice of chilled pink grapefruit for garnish.
