The Winter Bloom bar has been created in partnership with Hepple Gin and is furnished with Soho House's Home products.
Over the 12 days to Christmas customers who shop at a Mulberry store in London will be given a voucher for a complimentary mince pie and gin cocktail.
Valentine Warner, co-founder of Hepple Gin, said: "On the simplest level both companies have been inspired by nature – the Mulberry tree and Juniper. Both trees are distinctive for their very individual, intriguing and pleasurable offerings."
