Viña Maria Teresa is a small section of Quinta do Crasto planted with a centenary vine. This is the oldest vineyard in the domain Quinta do Crasto. Despite its low productivity, old vines produce highly concentrated fruits, which makes it possible to obtain wine of great complexity. This wine is produced only in good years and is regularly recognized as one of the best wines in the world. In 2015, only 5,385 bottles were produced, they are stored quietly for 30 years, and maybe longer.
