The Saskatchewan government says it will vigorously defend Canadian interests in an appeal involving a beer tax in Alberta.

An internal trade panel ruled earlier this month that Alberta providing what amounts to beer tax rebates to its small breweries discriminates against out-of-province beers.

The panel gave Alberta six months to change the program, but the province is appealing the decision.

Dustin Duncan, Saskatchewan's acting minister responsible for trade, says the government is disappointed that Alberta has decided to appeal.

Duncan says the panel decision supports a level playing field for beer, which is good for consumers and the Canadian craft beer industry.

He says the Alberta government "needs to do the right thing and comply with the ruling."
