Guilherme Müller Filho, who shared this dream with his partner, responsible for the executive and financial department, sold cachaça in the region and transported the drink from the mills to the headquarters in wooden tanks. Everything was made on the four wheels of his Ford F-8.

The company that bottled 51 in 600 mL beer bottles started bottling it in 1-L transparent containers. At the end of the decade, the name became Müller Franco Ltda., and Cachaça 51 became more attractive, with a new label and aluminum dropper.

In 1974, the company took another critical step. To meet the demand of a market in expansion, Mr. Guilherme imported the cutting-edge bottling line of the time. Recurrent investments in technology and a pioneering quality management policy resulted in growth and generated outstanding production records.

At the end of the decade, the concept “51 - A Good Idea” emerged, becoming a motto and quickly gaining a trademark. With this, 51 marked the advertising market as the first cachaça with professional and integrated communication.

The company underwent significant restructuring, with investments in the training of cachaça specialists, such as managers, sellers, and marketing promoters, responsible for operating an expanding market. To optimize contact with customers, the company implemented new organizational structures and commercial offices in all regions of Brazil.

In 1983, a new name emerged. Caninha 51 Indústria e Comércio de Bebidas Ltd. advanced with investments in market research to understand consumers and their expectations regarding the product.

In this decade, the company acquired the Taboão farm in Pirassununga/SP, where it is currently located.

A remarkable moment in the company's history. Cachaça 51 became the leader and started being exported. Japan was the first country to purchase it. Acknowledgement for the effort and dedication came through significant certifications: ISO 9001:2008 (Quality Management Systems) and ISO 14001:2004 (Environmental Management Systems).

The decade was marked by remarkable commercial results and another important name change: Indústrias Müller de Bebidas Ltda. During this period, Cia. Müller de Bebidas – NE was established in Cabo de Santo Agostinho/PE, a promising manufacturing facility capable of meeting the demand in the Northeast. At that time, Conhaque Domus, the first cognac in a transparent glass container, was launched in the market. Another great launch was the Caipirinha Mix 51, which revolutionized preparing the most Brazilian of drinks, the renowned caipirinha, using an advanced freeze-drying technique, which combines lemon and sugar. At that time, Terra Brazilis also reached the market, a cachaça with an exclusive flavor and aroma, being the result of the aging part of its production in oak barrels.

The company consolidates itself as Companhia Müller de Bebidas and moves with the launch of 51 Ice, the soft drink that is the perfect blend of Cachaça 51 with fruit. An innovative product - the first Cachaça-based Ice category. In this stage, the company reinforces the Quality Programs to optimize processes and offer an ideal structure to employees.

Over the years, the company has proven that diversification, innovation, and quality are the main cornerstones for growth, consolidating the export of Cachaça 51 in more than 50 countries.

In 2013, cachaça was recognized by the Alcohol and Tobacco Tax and Trade Bureau, a US government agency, as a legitimately Brazilian product, giving visibility to the country for its original production.

Cia. Müller became one of the leading centers for generating jobs in the sector, with more than 1,300 positions, being an international reference in sustainable development and economic growth, thanks to the permanent implementation of quality, health, and environmental management programs, in addition to cutting-edge technology centers established in all operational areas of the company

Companhia Müller de Bebidas is a living organism that does not stop. The search for improvements in practices and processes is constant and has resulted in significant national and international certifications, such as ISO 9001:2015, ISO 14001:2015, in addition to Kosher, Etanol Verde, and OHSAS 18001:2007.
