The single-vineyard 2007 Chianti Colli Fiorentini Riserva Vigna La Quercia is open and expressive in its vibrant dark fruit, grilled herbs and spices, all of which come together nicely on a soft, accessible frame. This shows less structure than the 2006 tasted alongside it, while still maintaining quite a bit of freshness, much of which likely comes from the addition of Cabernet Sauvignon to the Sangiovese. Anticipated maturity: 2010-2017. This is a lovely set of new releases from Castelvecchio. Consulting oenologist Luca D’Attoma has worked here since 2003. A 100% Sangiovese is also on the horizon, and should be a fascinating wine given the progress the estate has made in recent years.
