Vincente Alarte (1711) knew a Castellão variety and referred to the variety's susceptibility to coulure.

Ageing Potential: Good, if the wines come from the right area (Setúbal). Ages well in barrels.

Blending recommendation: Aragonez, Trincadeira, Moreto (young wine), Alicante Bouschet.

Wine Descriptors: The wines of this variety have a garnet colour and pronounced fruity aroma of blackcurrant and fruits of the forests. With ageing, it acquires hints of compote, and even of the meatiness of wild game. In the mouth, the wine is smooth, balanced with fresh acid, and has a lasting finish. It should normally be drunk early, when it is at its best (Paulo Laureano).

Wine quality: Very pleasant, varies with climate and soil. Under ideal conditions this could become a wine of some importance.

Variety Characteristics: Rate of multiple bud bursts, susceptibility to coulure and millerandage. Cultivation in unsuitable regions can lead to excessive yield, or significant loss of quality.
