Stevens Point Brewery, the US craft beer producer, plans to invest US$1.5m in boosting its production facilities after seeing double-digit volume growth in 2014. 

The Wisconsin-based firm, the country's 35th biggest craft brewer by volume, will install a new can filler, new brewing and control equipment – including a 300-barrel bright beer tank - and renovate its gift shop. 

The can filler will boost the brewery's capacity for producing 16-ounce cans, which the company said is “one of the hottest packaging trends in the (US) craft beer market”. 

Two extra salespeople and another quality control technician will also be recruited, the firm said this week. 

Joe Martino, an operating partner at Stevens Point Brewery, said it saw “particularly strong sales” for its Ciderboys hard ciders in 2014, while total group production volumes were up "double digits". 

“Investing in our people and infrastructure to ensure our production capacity keeps up with consumer demand is a key ingredient in our recipe for continued growth,” he added.  

The privately-owned company, founded in 1857, said this year is the sixth consecutive year of major expansions and between 2010 and 2014 around $7m has been invested in the brewery.
