Skinners Brewery has expanded its operations, after buying 10,000 square feet of storage and distribution space next to its headquarters in Truro.
The company spent £50,000 adapting the former Truro Farm Machinery buildings in the Newham area of the city, and has closed its Chacewater and Devoran 'satellite' sites as a result of the investment.
"We were bursting at the seams at Newham, and the development has not only streamlined our operation but also doubled our storage capacity here," said brewery chief executive Steve Skinner.
"It will be particularly useful in helping us handle our increased bottle sales, which have been boosted by the big success of our national sales through Waitrose."
Skinners Brewery was founded in 1997 and employs 30 staff. The partnership with Waitrose started in 2009 and sees three Cornish ales sold at supermarket outlets nationwide.
"Our success with Waitrose has been very encouraging, but the lion's share of our sales remains right here in Cornwall," said Mr Skinner.
"We regard ourselves as very much a Cornish company in all aspects and the main focus will continue to be on our home territory."
