Sparkling Wine Bottega Gold Prosecco. Bottega Gold is a Prosecco DOC, obtained by the vinification of Glera grapes. The elegance, freshness and liveliness of its bubbles stem from the beauty and tradition of its territory, where unmistakable panoramas are shaped by vineyards. The cultivation area of Glera grapes is located in the hilly area of the province of Treviso up to the slopes of Valdobbiadene, which is close to the Venetian Prealps. This area is characterised by long but not excessively cold winters and by hot but not sultry summers. The vines in this region grow on different types of land, each characterised by a variety of soils, exposures and slopes that make this Prosecco a wine with many nuances. The hilly terrain is subject to high temperature ranges between day and night. This variation in temperature enables the development of finer, more elegant and at the same time more intense aromas.
