Lots of stores here in Winnipeg, Canada. It seems that many have banded together to become a small franchise. I think that wine shops here are under promoted. Basically you have to want to make wine on your own and then visit the store. The stores don't seem to do anything to draw in new customers, ie wine tastings, classes, etc.
In my opinion the franchise type stores that are clean and convenient are the stores I avoid. They all offer the same limited supply with very little new and exciting. The proprietors also seem more like hired hands than knowledgeable wine makers.
The smaller "mom and pop" type places are crowded, harder to get to and generally disorganized. I like em. These are the places that have a few kit wines to sample and have a varied and constantly changing selection of goods. I visited one yesterday That had a huge selections of wine kits plus more additives than I'd know what to do with. Plus they had some fine looking beer kits including what looked like a selection of locally made microbrew style kits. Also they had barrels or hops and grains for you to brew up your own beer. And just for kicks, at the back of the store, was a sizeable game shop selling everything from ping pong tables to dungeons and dragons type goods. It sure beats a wall full of one brand of wine kit.
Finally. I try to shop at stores that offer a service too. Rental equipment is a must and some offer bottle cleaning, CO2 tank rentals, etc. Good advice is also very important to me.
