The grapes used for making Prado Enea, along with those for Torre Muga, are always the last ones to be brought into the winery. This late picking ensures ideal ripening. The grapes are then fermented naturally in 10,000-kilo oak vats with no temperature control or added yeasts. The maceration time can vary and may go on for up to twenty days. This wine is aged in 16,000-litre capacity oak vats for twelve months and then (minimum) thirty-six months in oak casks and (minimum) thirty-six months in the bottle. After cask-ageing the wine is gently fined using fresh egg whites.
