Let's say you're sitting the Court of Master Sommeliers exam and you come across a wine that's made from a particularly indistinguishable non-noble grape variety. Your mind filters through all the possible sensory descriptors but you keep coming back around to "grapey".
"Grapey"? All you've got is "grapey"?
You whisper this word to the examiner. She says "Is that all you've got, 'grapey'"?
"Yes" you reply. "Grapey is what it is".
"You don't get the bright ruby color, tart plums and a hint of sous bois on the palate?" she asks.
"Yeah, but it's still grapey. Overwhelmingly grapey. It's smooth, soft, and easy to drink. It's not about acidity, it's about its Cesanesity. At the end of the day, it's grapey."
At this point, your examiner slaps you across the cheek with her velvet glove, forcibly rips the Level III lapel pin from your jacket and summarily exiles you to the perdition of a job at the local Shakey's Pizza outlet where you stand behind the counter in a tuxedo, draped in multiple tastevins as you dole out carafes of Chablis, Burgundy, and Rosé from 18-liter boxes.
The 2008 Corte Dei Papi Cesanese del Piglio was the first red wine coming from Lazio to receive the DOCG designation. It's made from a grape called Cesanese di Affile (Piglio is one of the villages within the region) which is related to Cesanese Comune (and people wonder why Italian wines confuse consumers so often!) but the Affile clone is generally of higher quality so one must assume that in a wine such as this (imported into the USA by Vias) that the preponderance of grapes would be from Cesanese di Affile. This is an excellent example of what happens when a few producers in a region decide to put quality over quantity. For a long time, the region was known only for Frascati - adding well-made red wines to the options increases the region's marketing potential significantly and serves to inspire other growers and winemakers to increase the quality of their efforts. Everybody wins.
On day two, the wine loses a bit of its exuberance but picks up more noticeable complexity. More structure is evident, and the acidity becomes more apparent amid the fruit. It still fits the "grapey" descriptor but it shows more elegance and structure, and works better with food (leftover turkey and Latini Trenette, in this situation). There are no overt signs of oak, and at about $15 it's one heck of a deal. Would I want a cellar full of it? Not really...it might evolve for a little while in the cellar but it doesn't strike me as the most complex wine I've tasted recently. Quite good stuff, but not totally inspiring.
Some excellent information on this wine and its DOCG can be found at Rob Tebeau's Fringe Wine blog (or @FringeWine) and some very thorough tasting notes of other wines from the DOCG were written up earlier this year by Arnt Egil Nordlien at Vinduet.
