(NYTimes) - By 10 a.m., the temperature has climbed to 33 degrees Celsius. A limestone bluff shimmers in the heat.

In Mediterranean landscapes like this, people slow down for the summer and time sometimes seems to stand still. Yet if there is wine-making region of France that has its sights fixed on the future, while keeping its links to the past, it is Roussillon.
