Personally I wouldn't recommend Craft Beer Market, their service is appalling, the beer list is totally unimpressive and the place is packed with bros. Big Rock wont blow you away but are an important figure in the scene. Wild Rose does good things for our city, and Village Brewery is starting to produce tasty stuff too (try their Wit). Your best bets for good beer downtown are:
- Hop n Brew (the best)
- Beer Revolution (good pizza, good beer list)
- National Beer Hall (kinda meh but maybe worthwhile)
- Wurst (lots of German stuff on tap, good German food)
Best beer stores:
- Kensington wine market
- Willow Park Liquor
- Bin 905
Calgary is one of the few cities in north america where you can buy Cantillon off the shelf, so I'd recommend that! I live in the downtown core, drop me a line and we can meet up for some homebrews/beers. Cheers!
