Slingsby Navy Strength Gin uses locally sourced botanicals from Harrogate including Primrose, sweet cicely, nettle, rhubarb, milk thistle, rosehip and Taylors of Harrogate green and jasmine tea. It's stronger and richer with an ABV of 57% which creates a great body and intensity whilst still retaining the classic smooth citrus base of Slingsby's mutli award-winning London Dry Gin. This gin continues the tradition of the Royal Navy's `proof test', whereby gunpowder can still ignite if gin is accidentally spilled upon it.
