We were in Edinburgh this month and visited the Pickering's Gin Distillery. Can thoroughly recommend this lovely Scottish Gin. They also let us try it with a slice of grapefruit. I now, ever since our visit, have grapefruit in my gin as it is so nice.
I would suggest G.&.T. drinkers to give the grapefruit a try.
If you are in Edinburgh, go and visit this Distiller and try the gin.
