In Nova Scotia, when one thinks of beer, one thinks of Alexander Keith's line of beers.  This brewer has become the de facto beer for the province over the years and can be found at basically any bar in the region. 

At the original site of the brewery, you can take a tour giving a glimpse into the history of both the brewery, as well as Halifax.  Actors and actresses dressed up in 19th century clothing provide the tour trying to make you feel as if it was still the 1800s.  They even put on a singing and dancing performance for you while you get to sample Alexander Keith's beers.  During the tour, you get to have two full beers to try, including the famous India Pale Ale.  For those underage, there are lemonade and iced tea options as well.
