Oysters and whisky? Why the pairing could have huge benefits for wildlife in Scotland

Scientists find that using oysters as water filters helps the bivalve and other species thrive – and could treble the amount of carbon going into the seabed

Good whisky needs pure clean water, which partly explains why distilleries in Scotland always seem to have such scenic, loch-side backdrops. And one of the best ways to filter that water is oysters.
