Creating the Wort
In order to be classified as Scotch Whisky it must be made in batches.
The first step of the process is creating the mash. This is achieved by putting the grist, liquid yeast and water in a mash tun tank. They are soaked three times, each with a slightly higher temperature than the last. Part of that third soaking is used in the next batch. This process takes around eight hours. Anything left in the tanks is repurposed for cattle feed, ensuring that nothing is wasted in the process.
The resulting liquid is called wort. From the mash tun it gets placed in one of the washback tanks made from Canadian Douglas Fir (pictured), where it ferments for 48-56 hours. The fermented wort (which is approximately 8% alcohol) is then ready to be distilled to create the new make spirit.
