Bottle sales predominate among microbreweries, including the large Growler (jug). Increasingly, craft brewers are packaging at least some of their products in aluminum cans. For example, Ottawa's Beyond The Pale Brewing Co. once used only bottles, including one- and two-litre growlers, but the company added a canning system in 2015. "If you are trying to put out a premium product, it's better for the beer to be in cans. It's more convenient, it's better for the environment, it makes a lot of sense," said co-owner Rob McIsaac. Most of their beer is now sold in cans. Cameron's Brewing Company in Mississauga, Ontario, also sell the majority of their beer in cans. Craft brewer Black Bridge in Saskatchewan is strongly in favour of cans, due to the lower weight ("we can transport more beer while reducing our carbon footprint") and much greater resistance to light and oxygen that can reduce shelf life in addition to lower packaging and shipping costs.
