As an expert sommelier and brewer, I have firsthand experience with the process of capturing CO2 in breweries. One innovative method that has gained popularity is the use of a machine called CiCi, which stands for “carbon capture.” This machine plays a crucial role in capturing and reusing the CO2 emitted during the fermentation process.
CiCi is designed to intercept the CO2 that flows from the fermenters through a network of pipes that snake around the brewery. This allows for efficient collection of the emitted gas throughout the brewing facility. The captured CO2 is then filtered to achieve a purity level of more than 99 percent, ensuring a high-quality end product.
Once the CO2 is filtered, the machine condenses it into a liquid form, making it easier to handle and store. This condensed gas is then stored in tanks or containers for future use. One of the common uses of the captured CO2 is to carbonate the beer itself, adding the desired level of effervescence to the final product.
The advantages of capturing CO2 in breweries are two-fold. Firstly, it helps in reducing the carbon footprint of the brewing process. By reusing the emitted CO2, breweries can significantly decrease their greenhouse gas emissions, contributing to a more sustainable operation. Secondly, the captured CO2 can be used for various purposes within the brewery, reducing the need to rely on external sources for carbonation or other applications.
In my personal experience, implementing a CO2 capture system in the brewery has been a game-changer. Not only does it align with our commitment to sustainability, but it also enhances the overall quality of our beers. The ability to control the carbonation process using the captured CO2 allows us to achieve consistent results, ensuring that every pint poured from the tap has the perfect level of carbonation.
To summarize, breweries capture CO2 through the use of machines like CiCi, which intercept and filter the emitted gas from the fermenters. The captured CO2 is then condensed into a liquid form and stored for future use, including carbonation of beer. This process not only contributes to a more sustainable brewing operation but also enhances the quality and consistency of the final product.
