Petra is a new winery, and has made great strides over the past 3-4 years. The vineyards are still a little young -- they were mostly planted in the 90s -- but the wines (especially this one) are already impressive in a fairly international key, and will improve considerably as the vineyards mature over then next 5-10 years. In short, if you like the style Petra is going to be a place to keep in mind. It's also pretty to visit; Petra's website has lots more information should you be in the area, and they will be able to help you find the wine near where you live too.
Returning to the wine, Ebo is a blend of 40% Sangiovese, 30% Merlot, and 30% Cabernet Sauvignon, and the wine I tasted was poured from a magnum (1.5 liter, or twice standard size) bottle; it's almandine ruby with black reflections and almandine rim. The bouquet is muted at first swish, though cherry plum fruit and some cedar do emerge with further swishing, as do greenish herbal notes, and the cherry gains in intensity with time. Quite polished. On the palate it's full, with powerful cherry fruit that gains direction from some citric acidity, and is supported by smooth sweet tannins that lead into a long clean citric cherry finish. Pleasant, and will do justice to a steak or roast beef, cooked rare. Considerable justice.
