Canada's Big Rock Brewery Income Trust has seen first-half earnings leap thanks to reduced costs and a one-off tax rebate.

Big Rock, based in the Canadian province of Alberta, yesterday (10 August) posted a 41% jump in net income to C$3.8m (US$3.4m).

Revenues inched up 1% to C$18.9m as sales of Big Rock's private-label beers rose. The company said profits were boosted by raising prices and reducing selling costs surrounding its stable of discount brews.

Big Rock said it was using a series of sampling programmes to promote its premium portfolio, which includes Black Amber Ale and Grasshöpper.

The company said the scheme would build loyalty around its brands "in the medium to long term".
