One of Canada's oldest microbreweries (established in 1984), GIB offers short tours on which smiling guides walk you through the tiny brewing nook. The brewery has grown exponentially since opening and most of its beers are now made off-site, although some excellent small-batch brews are still made here on the island. The tour concludes with samples in the Taproom.
You can also buy some takeout in the adjoining store; aim for the single bottles of small-batch brews since they're not easily available elsewhere. Need a souvenir for a beer fan back home? This is also a good spot for branded T-shirts and bottle openers. The island is also home to another brewery, a distillery and even a sake maker so it is a good destination for a compact booze crawl.
