These are interesting times in Tuscany. There is no doubt the region is in the midst of a profound stylistic evolution. A growing number of estates are moving in the direction of more natural viticulture. In the cellar, new oak is down and the use of neutral vessels is up. Cement, once virtually forgotten, is making a huge comeback. As it turns out, the makers of cement tanks and vats are now taking as long as six months to fill orders, something that was unheard of up until very recently.
