The Pure Art of Whisky: Why Callington Mill Distillery Neither Chill Filters Nor Flocks

When it comes to the crafting of a fine single malt whisky, every step matters. From the quality of the barley to the whispering influence of oak barrels, every detail plays a role in giving life to the spirit that enthralls connoisseurs worldwide. At Callington Mill Distillery, we have always upheld the principles of purity and authenticity. That's why we have chosen not to chill filter or use flocculation techniques on our whiskies. Let’s delve into the reasons behind these decisions.

The Essence of Chill Filtration 

Chill filtration is a process often used in the whisky industry to remove certain compounds from the spirit, mainly fatty acids, esters, and proteins. The goal? To prevent the whisky from becoming cloudy when cooled or when water is added. Here's how it works: The whisky is cooled down, often to around 0°C (32°F), which causes these compounds to solidify or "flock." These solid particles are then easily removed through filtration. While this process does produce a clear spirit, it's essential to understand that these compounds – the very ones removed during chill filtration – play a significant role in the flavour and mouthfeel of the whisky.





The Case Against Chill Filtration


By opting not to chill filter, we preserve the richness and full-bodied character of our whisky. The compounds that might be removed in the process are responsible for enhancing the texture and depth of the spirit. They add to the overall experience, making each sip a journey of complex tastes and aromas. Yes, our whisky may turn slightly hazy under cold conditions or when water is added. But this is a natural testament to its authenticity, a sign that you are enjoying the whisky in its most genuine form.




Saying No to Flocculation 

Flocculation is another method to clear up the spirit - by removing fats and esters that solidify or ‘flock’ under cold temperatures on bottom of a vessel - the very fats and esters that add flavour, richness and mouth feel to the whisky. While effective in making the whisky ‘look’ clear, it's another step away from the purity that defines Callington Mill Distillery. Our approach has always been to let nature and craftsmanship dictate the course of our whisky. By avoiding artificial means to clear the spirit, we ensure that our patrons experience the whisky as it was meant to be: pure, unaltered, and full of character.







At Callington Mill Distillery, we believe in transparency and dedication to the art of whisky-making. Our decision to eschew chill filtration and flocculation is a testament to our commitment to delivering a product that is as close to its natural state as possible. Each bottle from our distillery is a celebration of tradition, craftsmanship, and the raw beauty of nature. By enjoying our whisky, you're not just savoring a drink; you're experiencing a legacy. 



Cheers to the authentic spirit!
