We just visited The Dominio de Valdepusa Winery in Toledo Province and were really impressed! The vineyards is where the focus is…these are some of the most high tech vineyards I ever seen! They have sensors that detect every miniscule movement and change in the vine….years of analysing this data allows them to know with precision the exact water needs of their vines. They believed that it is very difficult to get good phenolic ripeness without over-ripe fruit and too low acid levels in hot viticultural areas. Their careful use of technology actually allows them to get a perfectly ripe grapes with good acid levels…this gives top quality, intense, yet fresh wines that age well.
