At 1 000 metres above sea level, Reto Raselli grows organic herbs for Pro Montagna organic mountain herbal teas. He and his family have been farming in the Val Poschiavo region of Graubünden for generations. Of the hundred or so valleys in Graubünden, Val Poschiavo is the southernmost, and its microclimate is perfect for growing mountain herbs. Intense exposure to the sun’s rays gives the herbs a particularly intense aroma. Reto Raselli and his team plant, nurture and harvest the herbs from the fields, which requires a great deal of manual labour.
