Ola Vasco,
I'm buying a small terraced vinyard and house just outside Mesao Frio (Santa Cristina), so about an hour and a half from your place.
I'm planning to learn how to do
water retention engineering, diversify the plants, and transition the house to
solar energy. I'm just learning Portuguese and would love any contacts and local advice for these kinds of projects. Thanks! Sarah
