A small fraction of the reds are bottled without any added sulfur and go to specific customers, but it's not a commercial wine. I tasted one of those bottles: the 2021 Els Escurçons. It is pretty, pale, perfumed, ethereal, vibrant and clean, with no fault or deviations. The regular bottling is more Priorat in style, even darker, a little wilder (à la Jura), with a touch of cider that is a bit disconcerting, characterful, with perfume and a faint earthiness, going toward a similar profile as the non-sulfured cuvée. The palate is serious and velvety, with some dusty tannins and a moderate 13.5% alcohol, lighter than the more-traditional Priorats, fine-boned and very tasty. A very unusual Priorat.
