Bottled in honor of Dona Antónia Adelaide Ferreira, this is a unique wine, made from a vineyard in Rio Torto mostly planted in the 1940s, traditionally planted as a field blend of more than 30 grape varieties. A very rare wine, only bottled in exceptional years, and in very small quantities (4.358 bottles).
Aroma
Very concentrated, with balsamic oak notes, fig, black plum aromas and tobacco.
Taste
Full bodied, firm, mature and silky tannins. Mineral notes with a very elegant, persistent and complex finish.
Vinification
The grapes, after a careful manual selection on the sorting belt, were de-stemmed and fermented in stainless steel tanks at a controlled temperature of 24ºC with mechanical remontage for 9 days.
Varieties
Adelaide comes from a parcel of very old vineyards (some more than one hundred years old) where a blend of more than 30 different indigenous grape varieties are planted, with predominance of the following: Touriga Franca, Rufete, Tinta Roriz, Tinta Amarela, Tinta Barrroca, Tinta Nascida, Malvasia Preta, Mourisco, Bastardo, Touriga Nacional, Tinta Bairrada, Tinta da Barca, Tinta Francisca, Tinta Carvalha, Moscatel de Hamburgo, Tinta Pomar, Piriquita, Moreto, Sultanina, S. Saúl, Casculho e Preto Martinho.
The soil is predominantly schist (black slate). These vines, planted in a density of 7,000 vines per hectare, yield on average 400g per plant, equivalent to 2,8 tons per hectare. This puts these vines amongst the lowest yielding per hectare in the world.
Ageing
Ageing and malolactic fermentation take place in 225 litre new French Oak barrels for 20 months.
