Choosing the best gas to tap your beverages
THIELMANN’s vast expertise of stainless steel beer kegging is now finding new areas of application for foodstuffs such as wine, juice, coffee, tea, and edible oils. Draft systems used with kegs require gas to propel the foodstuff from the keg to the faucet, but also to maintain the correct gas concentration in the foodstuff. Selecting the optimal gas (or gas blend) is therefore vital and must be done carefully. The specificities of carbon dioxide (CO2), nitrogen (N2) and the so-called “beer gas” (CO2/N2blend) affect the storage and dispensing of foodstuffs stored inside the keg and must therefore be clearly understood. Carbonation, which affects the taste of beverages, must be monitored closely to ensure that the organoleptic properties of the foodstuffs remain unaltered or are altered only as desired by the producer.
