Craig Pinhey, a Maritime writer on beer and other beverages, laments the restrictions on the interprovincial beer trade in Canada.

At one point beer could only be sold in provinces where it was brewed. Although not true anymore, we've not come very far. In New Brunswick, the rules give huge advantages to Atlantic breweries, thanks to pricing agreements. Out-of-province brews are tagged with a premium, so they sacrifice profit to hit the same shelf price. The exception is that local guys, including Moosehead and Labatt Halifax, sell to the liquor boards in each other's province at the preferred price.

Craig continues with a litany of trade restrictions that are in place in this country, and calls for a common, national approach to beer, wine and spirits laws. Sounds good to me. Would American readers care to comment on inter-state trade ~ is it pretty much unrestricted? Are there any similar pricing differences/increases for out-of-state beer? Do any other countries have internal beer trade barriers?
