Cornelius Brand Guidelines: The 1931 Anoka Soda-Fountain Maker Behind the Corny Keg

A Minnesota fountain maker since 1931.

Cornelius dates itself to 1931. The company’s own timeline says it was founded that year in Anoka, Minnesota, as a manufacturer of soda fountain equipment — the dispensing gear behind the counters where carbonated drinks were mixed and served.

The company tells the rest of its story decade by decade. It says it pioneered post-mix dispensing in the 1950s, mixing syrup and water at the point of service rather than shipping drinks ready-made; expanded into frozen beverage and ice machines in the 1970s; introduced electronic dispensing controls and widened its international operations in the 1990s; launched its DMS platform for remote monitoring and diagnostics in the 2000s; released the IDC Pro touchscreen dispenser, with IoT connectivity and a modular service design, in the 2010s; and in the 2020s introduced what it calls next-generation intelligent beverage systems that work with third-party platforms. Those dates and the claim to have pioneered post-mix are the company’s own.

Today Cornelius says it has more than 90 years of experience, serves more than 100 countries and works in four product categories: fountain, frozen, juice and ice. Its mission line is “Pour the world the perfect beverage — every time, everywhere, for everyone,” and its about page sets out the plan to turn “the beverage station into the beverage system,” with connected dispensers that report their own status.

The keg that took the name.

The Cornelius name travelled far beyond restaurant counters through a stainless-steel canister. English Wikipedia, citing Charlie Papazian’s The Complete Joy of Homebrewing, describes the Cornelius keg — also called the “Corny keg” or “soda keg” — as a container originally used by the soft-drink industry, first made by Cornelius, Inc. Ready-mixed, or “premix,” soda was held in it under pressure and pushed out by gas.

The design is simple. Wikipedia describes a steel cylinder with a large central lid for filling and cleaning, and two ports, one for gas in and one for liquid out. There are two quick-connect styles that do not fit each other: pin lock, historically used mainly by Coca-Cola, and ball lock, used mainly by Pepsi. Kegs were also made under licence by other manufacturers, including Firestone and John Wood, often with different threads on the posts.

As bag-in-box syrup packs and post-mix systems took over, the kegs became largely obsolete in the soda business, Wikipedia says, and surplus ones were taken up by homebrewers. The most common size holds five US gallons, about 19 litres, which matches a typical home-brew batch, so one keg can stand in for about fifty bottles. The article adds that the kegs suit carbonated or nitrogenated drinks, and are now used for home-made soda and nitro cold brew coffee as well as beer.

The current catalogue is a long way from that steel can. Its fountain line includes the IDC Pro, which Cornelius calls its most advanced ice and beverage dispenser, the Enduro ice and drink dispensers and CB drop-in units; frozen carbonated drinks come from the Viper, in two-, three- and four-flavour versions; juice comes from the Quest Elite; and ice from the Nordic Elite cube machines, which the company announced in November 2025, and the Chunklet. Its 2025 newsroom also announced refrigerant options for the Viper and the juice dispensers, and an IDC Pro software update with customisable branding templates for the touchscreen.

Fountains, fonts and keg cellars.

Beverage dispensing makers sell to two very different counters. In a pub or bar, the visible parts are the font on the bar top and the tap handles fixed to it, which usually carry the brewer’s branding while the equipment maker’s name sits on the hardware underneath. In a quick-service restaurant, the visible part is the post-mix tower or self-serve dispenser, where drink brands and, more and more, touchscreens take over the front panel.

Most of the machinery is out of sight, so the makers explain it on paper. Catalogues and spec sheets lean on cutaway diagrams of coolers, carbonators and insulated beer lines, on line drawings and wiring diagrams, and on photographs of keg cellars and cold rooms where kegs, gas cylinders and couplers are connected. The literature is written for installers, service technicians and distributors as much as for the owner of the bar.

The trade meets at shows. The National Restaurant Association Show in Chicago gathers foodservice equipment, including fountain dispensers and ice machines; BrauBeviale in Nuremberg covers brewing and the wider beverage supply chain; and the Craft Brewers Conference in the United States brings draught-system suppliers face to face with brewers. Makers also name certifications, audits and sustainability ratings in their own newsrooms, as Lancer does with its ISO certificates.

Ownership often runs through larger groups. Lancer has been part of the Japanese refrigeration maker Hoshizaki since 2006, according to Hoshizaki’s corporate history, and Cornelius went to Berkshire Hathaway when the British engineering group IMI agreed to sell it in 2013, according to English Wikipedia; its website now says it is powered by Marmon Foodservice Technologies. This guide sets out what can be checked about each maker and marks what rests on the company’s own word.

From IMI to Marmon and Berkshire Hathaway.

By 2013 Cornelius belonged to a British engineering group. English Wikipedia’s article on IMI plc, formerly Imperial Metal Industries, says IMI announced in October 2013 the disposal of two non-core subsidiaries to Berkshire Hathaway, one of them the Cornelius Group, a beverage-dispensing machine business, so that IMI could concentrate on control valves; it cites The Telegraph of 16 and 17 October 2013.

Inside Berkshire, Cornelius sits with the Marmon Group, the Chicago holding company that Jay and Robert Pritzker founded in 1953 as Colson Corporation. English Wikipedia says Berkshire took a controlling interest in 2007–08 and became sole owner in 2013, and lists Cornelius under Marmon Foodservice Technologies. The Cornelius website carries the line “Powered by Marmon Foodservice Technologies” and says the brand is “backed by Marmon Holdings and Berkshire Hathaway.” Around the equipment, the site says, Marmon Foodservice Technologies offers Marmon Link for managing equipment over its life and Marmon Renew for certified refurbishment.

The website frames the brand’s next chapter around software and service: Cornelius DMS, which it describes as a cloud platform for real-time diagnostics, performance tracking and maintenance alerts, together with over-the-air updates and what it calls an open architecture that works with third-party platforms. Those are the company’s descriptions of its own products.

For a design guide, Cornelius shows how a fountain-equipment name can travel far beyond its own catalogue, from a 1931 soda-fountain maker to a keg that homebrewers still call by its name. Compare Lancer, the San Antonio dispenser maker owned by Hoshizaki, and Hamilton Beach. For this guide we use a fountain red, a stainless grey and a cream with a sans, an unofficial interpretation; no product or logo is reproduced.
