Casa Coste Piane is a small estate (a piffling 5ha and only 30,000 bottles) in Santo Stefano, heart of the Valdobbiadene area. For generations their wine had been sold in bulk but since 1983 they decided to bottle the production themselves. The vineyards lie on slopes close to the cellar. The vines are on average 60 years old (some are pre-phylloxera!!) and their roots can grow up to 30-40 metres long. This Prosecco is a gem, it is one of the few made in the champenoise method wherein the second fermentation takes place in the bottle. Harvest is usually between the last week of September and the first week of October. In April the wine is bottled without the addition of yeast and sugar, subsequently the indigenous yeast contained in the wine starts a second spontaneous fermentation that lasts for approximately four weeks. After this the wine spends a further four weeks sur lie. The process of ―disgorgement‖ is not practised, therefore the yeasts are still present in the bottle… any haziness is entirely natural. This fine Prosecco is clean, pure and elegant, mineral with crackling citrus notes, easy-drinking and at the same time complex.
