Gases and Specialty Products for Beverage: MATHESON offers gases - in a variety of package configurations - for beverage carbonation and also for beverage nitrogenation.
Carbon Dioxide for Beverage Carbonation and Dispensing.
Carbon dioxide is essential in delivering the "fizz" to water, carbonated soft drinks (sodas), and beer. Carbon dioxide is also used for product blanketing, pressure transfer, and bottle purging (during filling of beer, for example).
Beverage gases used for product dispensing are offered in a range of mixes ranging from 25% CO2 (in nitrogen) to 100% CO2. The exact mix you choose will depend on the product you are pushing, the distance you are pushing it, and the desired carbonation level at the dispenser.
Some carbon dioxide users are being supplied liquid carbon dioxide, which is stored not in high pressure gas cylinders, but in a low pressure insulated liquid vessel (liquid CO2 is very cold) and then used as a gas. Beverage gas mixtures can be mixed on site from a supply of nitrogen (from cylinders or by a nitrogen generator).
Nitrogen for Craft Beer Production and Nitro Coffee.
Nitrogen is essentially inert, and is used as the balance gas when combined with CO2 (CO2 being the active component), but many "heavy" beers - and also "Nitro" Coffee - require higher concentrations of nitrogen.
Nitro taps are used for ales and stouts. Nitro taps are also used for iced coffee. The nitrogen imparts a creamier taste to both ales and coffees.

Nitrogen is also used (and generally preferred over CO2) for product blanketing, pressure transfer, and bottle purging (during filling of beer, for example).
Oxygen for Beverage Applications.
Beverage gas containing oxygen is used for yeast activation. Also see the section of this website specifically dealing with Craft Brewing.
