Producers of some of the most popular Nova Scotia wines, Jost Winery uses a variety of grapes that has been cross-bred over a century ago to withstand the unpredictable Maritime climate, and thus is resistant to disease, requiring less spray and preservative. To fertilize the vines. Hans Christian Jost uses cow manure from a local beef farmer. A few years ago he took 600 tonnes of crab, lobster and oyster waste from a local fish processing plant to help fill his fields with nutrients, the benefits of which will last for decades. You can still find the odd oyster shell out in the rows.
