PERSEPHONE BREWING CO.

If you pick up bottles and cans of Persephone's famous Dry Irish Stout at the liquor store but have never visited the Gibsons brewery, you might not know that it runs an 11-acre farm and grows its own hops and barley, plus apples for cider.

Most breweries use an average of about four litres of water for every litre of beer they create. Persephone has cut that number in half, and treats its wastewater so it can contribute to the health of the local watershed. •
