Alberta's new beer markup is set to take effect on August 5, but a University of Regina professor said Saskatchewan criticism, "doesn't have a leg to stand on."

Saskatchewan-based Great Western Brewing company is expecting a "substantial" hit to its beer sales after recent changes announced by Alberta that will see a standardized beer markup rate for all beers.

As the government of Alberta moves toward changing its beer tax system, the Saskatchewan government is voicing its concern.

The government of Alberta is changing the way it marks up beer, moving away from a graduated mark-up structure announced in the October budget to a flat price for all brewers no matter how much beer they produce.
