Lots happening at the Brewery again with our latest investment into sustainable technologies…
Temperature control is one of the most crucial elements in brewing. It needs to be regulated and stable throughout the whole fermentation process to ensure the yeast ferments correctly to get the intended flavour profile and alcohol volume of the beer. A chiller facilitates this temperature control by pumping glycol coolant around insulation jackets which surround all our fermenting vessels.
However, this chiller is VERY thirsty when it comes to energy consumption. In fact, it’s the biggest energy consumer on site… And we were in need of an upgrade.
So as well as a new glycol chiller, we’ve invested in a ‘Dry Air Cooler’, also known as a ‘Free Cooler’. This utilises the cool ambient temperatures we’re all too familiar with in the British Isles by sucking in cold air to bring the glycol down to the required temperature.
So when the outside temperature drops to 4 degrees or below, our glycol chiller switches off and the temperature of our fermenting vessels is regulated by using the air around us… Pretty ‘cool’, heh?
