Vegetable scents, volcanic vineyards and a harvest festival

As the leaves start to turn gold and red, we take stock of the new season. We head to a harvest festival in the Åland islands, learn about sustainable farming for a London florist and an Italian skincare brand, and sample some vegetable-based scents with perfume expert Lizzie Ostrom. Plus: we speak to a winemaker on Mount Etna to learn about the unique qualities of wine produced on a volcano.
