In addition to offering gin tastings at the Pro-Am drinks receptions, their staff will be on-hand in the spectator village with a fully-stocked bar.
The St Andrews-based producers are best known for their 'Core Gin' range, which includes Original Gin, Golf Gin, Oak Gin, Hop Gin and their famous, pink Love Gin.
Paul Miller, founder of Eden Mill, said: "Coming from The Home of Golf, it is great for Eden Mill to be involved in supporting the Willow Senior Golf Classic."
The Willow Senior Golf Classic helps raise funds for the Willow Foundation, a charity which which delivers Special Days for seriously ill young adults between the ages of 16-40. Established in 1999, the Foundation has fulfilled more than 15,000 Special Days.
The charity was founded by former Arsenal goalkeeper and TV presenter Bob Wilson and his wife Megs as a lasting memorial to their daughter Anna, who died of cancer aged 31. Anna created the idea of ‘Special Days’ which became a focus for quality of time and quality of life for her family and friends.
Entry to the Willow Senior Golf Classic is free with a £5 charge for car parking - all proceeds go to the Willow Foundation.
