The 2016 Conegliano Valdobbiadene Prosecco Superiore Rive di Ogliano Millesimato Extra Dry (100% Glera grapes) offers a touch of sweetness that adds to the creamy layering of the wine. Lemon blossom, sweet peach and Golden Delicious apple rise slowly from the bouquet. There is just enough acidity to keep the wine in easy-drinking harmony. Vineyards are planted on limestone alluvial soils at 150 meters above sea level.

The 2015 Conegliano Valdobbiadene Prosecco Superiore Rive di Ogliano Millesimato Extra Dry is a cooling and steely Italian sparkling wine. There is a touch of sweetness here (that is characteristic of Extra Dry Prosecco Superiore), but the residual sugar appears reduced compared to the wine's many competitors. The effect is linear and bright with citrus, jasmine, white rose and crushed flint. The effect is simple but very satisfying.

The 2013 Conegliano Valdobbiadene Prosecco Superiore Rive di Ogliano Millesimato Extra Dry is fresh and perky from the start with steely effervescence and sharp aromas of white peach, lemon curd and crushed mineral. Attractive crispness and balanced acidity makes a great counter point to the subtle levels of sweetness you get at the back. There's even a touch of spice or milled peppercorn at the end.

The 2011 Conegliano Valdobbiadene Prosecco Superiore Rive di Ogliano Millesimato Extra Dry makes a good argument for the longevity of Prosecco Superiore (a wine that is normally consumed within a year of release). From the Ogliano Rive at the far eastern part of the appellation, this cheerful sparkling wine shows a greater sense of width and depth in the mouth followed by candied lemon and peach. The perlage is fresh and steady, just like a newborn Prosecco Superiore. I'm betting this wine will last another two or three years.
