Redesigning the pot still

VITRIOL 1 and 2

It's best to let Eric, who designed the original geodesic still take over the explanation of the naming of the stills..

“Visita Interiora Terrae Rectificando Invenies Occultum Lapidem" is the meaning of the alchemical acronym V.I.T.R.I.O.L.

Translated from Latin: “Visit the interior of the earth and by rectifying (purifying) you will find the hidden (philosopher's) stone.” 

The motto was first published by the 15th Century alchemist Basilius Valentinus, appearing in L’Azoth des Philosophes, and is the search for the philosopher stone, turning base products into gold, which is what we are doing....basically.

why geodesic?

copper contact

The purpose of the copper in the still is to allow interactions at the molecular level between suphur containing products of the fermentation and the metal. This reaction removes these bitter, sulphurous compunds by ultimately converting them to copper sulphate that stays in the still and is discarded. The more copper contact, the more sulphur is removed and this lets the undelying notes of the fermentation through. The geodesic also allows for reflux, with vertical sides and flat panels.

fireside plans

scratch built

Designing the pot stills from scratch in Autocad. The brief was maximum copper contact, with high internal reflux. The flat panels of the geodesic allow just that, creating a refined spirit.

spirit still

Eric assembling the base of the spirit still. We cut the panels on a water jet then hand bent the tabs before rivting them and welding the seams.

halves awaiting assembly

joining the halves

would prove the hardest part. The inital idea to allow easy cleaning the still was make in 2 sections. Heat deformity and gasket material would prove tricky....

from surgery to welding

a steep learning curve

Mark welding the spirit still stand. The project was a proof of concept, but VITRIOL 1 is still in use today.

PID controlled heating elements are swappable for easy cleaning and replacement.

New Stills

We turned to the experts for our new stills, working with Speyside copper works to bring our old designs to life


The team decided on a tadpole shaped still for the wash, predominantly for our peated character. Less reflux and a faster run with the lyne arm is pointed downwards allows more of the peaty flavour to run into the low wines.


The spirit still retains the geodesic shoulders and is designed for more reflux, with a hourglass neck and horizontal lyne arm.


electric fired steam

The wash still has 2 sets of steam coils, alowing for rapid heating of the wash. These are supplied by 3x electric steam fired boilers, powered by 100% renewable energy

Prime energy

100% Carbon Zero Power

We are committed to our carbon zero goal and have partnered with Prime Energy to supply our power for the stills and the brewhouse.

speyside copper works

hand built the traditional way

Our beautiful new stills were made in Speyside. 6mm thick base and 4mm neck and shoulders, They are beautiful as well as functional.

V.I.T.R.Io.l MK2

Here are the shoulders of the spirit still talking shape. After consutation with Garry and Derek we have incorporated the design in to the spirit still.

tadpole wash still

Here the shoulders of the wash are nearly complete. Its 2m diameter at the base and when complete stands 5m high. It is designed for minimal reflux for a peaty low wine.

the future of steam

electric steam boilers

 The use of fossil fuels in the distillery industry is a dirty secret. Oil, gas and diesel still make up the vast majority of energy sources for heating water and the stills. We chose electricity, 100% renewable, sourced from hydro and geothermal as our power source. Our first stills, VITRIOL1&2 were direct electric fired, using heating coils. 

Our New Stills, VITRIOL 3&4 use electric fired steam, again 100% renewable energy. The electric fired boilers, generate 570kgs of steam and hour at nearly 95% efficiency.
