Monteith's Brewery Company was originally a family-owned brewing company until it was bought by DB Breweries. Additionally, DB Breweries is owned by Heineken Asia Pacific, since 2012, so Monteith's is actually a product of Heineken.
It continued to brew its beers on the West Coast of New Zealand until DB decided that the cost of keeping production there was no longer viable. The Greymouth brewery was closed on 22 March 2001, but reopened four days later following a public outcry.
The beers are now produced in Auckland, and Timaru as well as Greymouth. On 25 July 2012, the newly transformed Greymouth brewery was officially reopened after 18 months of refurbishment.
DB Breweries attracted controversy during a legal battle over the exclusive use of the name Radler. Radler is a style of beer, in the same way that Pilsner or Stout are. However, DB has trademarked the term "Radler" since 2001.
The Society of Beer Advocates asked the Intellectual Property Office of New Zealand (IPoNZ) for the brewery's Radler trademark to be revoked. The issues of this trademark were brought to public attention when a small independent brewery (Green Man) in Dunedin, Otago released its own Radler (since renamed to Cyclist).
IPoNZ handed down its decision on 14 July 2011. The trademark has been upheld, citing the fact that the term "Radler" was not well known in New Zealand at the time the trademark was taken out.
