The first link of a beer maker's supply chain is the soil.
"Guinness is going green. The Irish brewery is launching an agricultural program to make its stouts more sustainable.
"It’s already tapped 40 Irish farms to join its pilot regenerative agriculture project, which involves working with the natural environment to put back more than it takes out. Soil management and crop production experts and suppliers are also on board.
"The initiative intends to reduce the carbon emissions of its barley production—a key ingredient in each black and white pint.
"The regenerative agriculture project has key goals, including improving soil health and its carbon sequestration potential; aka having the soil itself store carbon before it becomes carbon dioxide gas, and enhancing biodiversity—or the natural soil fertilization, nutrient recycling, erosion control, and crop/tree pollination that keeps the ecosystem healthy."
