Principia Mathematica is an exquisite white wine created by Alemany i Corrió in the D.O. Penedès, aiming to provide a complex and elegant expression of Xarel·lo. This wine is made exclusively from Xarel·lo grapes from vineyards on limestone and clay-limestone soils. Fermentation occurs using indigenous yeasts in French oak barrels, and the wine is aged for around 9 months. It then rests briefly in stainless steel tanks and is bottled unfiltered and unclarified. Principia Mathematica stands out for its freshness, with aromas of ripe fruit like pear and peach, alongside citrus and herbal notes. On the palate, it is broad, with good acidity, a saline character, and a light bitterness that contributes to its freshness and persistence.
