(Sustainablebusinessforum) - Because of strict alcohol regulations in Canada, the Liquor Control Board of Ontario is the single largest buyer of wine in the world. Last year, they announced that by 2013, all bottles of wine that retail for less than $15 would have to weigh less than 420 grams when empty, which is 15-20 percent lighter than the standard bottle of wine. “It's one of those cases where the industry led the regulators,” says Ann Thrupp, Manager of Sustainability and Organic Development at Fetzer Vineyards. “We were one of the early innovators to adopt lighter weight bottling on a very large scale.”
