Walter Gregor's, Scotland's first tonic water, was founded by Claire Rennie. The brand is named after a 19th century minister who served the historic parish of Pitsligo on the Aberdeenshire coast by order of Queen Victoria. Gregor was a keen plantsman and spent a lot of time tending to the walled garden in his former manse in Peathill. The Rennie family purchased the manse and garden in the 1960s and Claire decided to make tonics using the walled garden to grow the botanicals as a testimony to Walter and his love for botanicals. The range now includes a classic tonic and a variety of flavoured tonics which can pair with a number of different spirits.
