Our Story

We make small batch tonic waters in Walter Gregor’s former parish of Pitsligo in Peathill, Aberdeenshire. We are based on our remote and rural farm which stretches across rolling countryside to the shores of the Moray Firth.

Here, we have built a modern bottling facility to make and bottle our hand crafted tonic waters and mixers where we also make Summerhouse Drinks craft sodas and lemonades.

We started making our soft drinks in 2014 when our founder, Claire Rennie, decided to stop complaining about the lack of great tasting, naturally made soft drinks and do something about it.

In 2015, we launched Walter Gregor’s Original Tonic Water to pair with the increasing number of craft Scottish gins that were being distilled. Since then we have been exploring and experimenting with a range of spirits and our mixers to develop new, exciting and inspirational serves.

Our Process

All our recipes are unique and developed and made in house by our dedicated team. We pasteurise in the bottle so that we don’t use any artificial preservatives and use fresh ingredients to infuse our tonic waters and mixers with natural flavours.

Because of our all natural pasterusing process and the shape of our CO₂ bubble, our tonic waters are not agressively fizzy. We find this allows the taste of the spirit to shine through and not overpower it.


Walter Gregor

Our tonic water is named after Walter Gregor, a 19th century minister who served our historic parish of Pitsligo by order of Queen Victoria.

As a renowned academic & plantsman, he was often found tending to the walled garden at his manse in Peathill, a stones throw away from our factory where we make all our drinks.

His love for botanicals and for this part of Aberdeenshire inspired us to make our tonic waters from all natural ingredients, right here in his former parish.
