Abbuoto

[1] Some ampelographers suspect that the Lazio grape variety San Giuseppe nero may be related to (or possibly a clone) of Abbuoto but so far DNA analysis has not yet confirmed such suspicions.

[1] Caecuban wine (Latin: Caecubum, Greek: Kaikoubos, Italian: Cècubo) was produced on a small vineyard in the low lying marshy region, south of Terracina (today's southern Lazio and northern Campania).

[2] An Italian wine expert and connoisseur Mimmo Albano tells a story that in some of the marshy areas around Lake Fondi about 50 miles south of Rome, there were some old, neglected vines of a type that was thought to be the ancient Abbuoto.

The grape tends to ripens in the middle of the harvest season (early to mid October depending on the vintage year) but can be prone to producing irregular and inconsistent yields.

[1] Abbuoto is found primarily in the Lazio region of central Italy where it associated with the villages of Fiuggi, Fondi, Formia, Monte San Biagio and Terracina.

Here on the southern slopes of Monti Prenestini south of Rome, the grapes are harvested up to a maximum yield of 14 tonnes/ha with the finished wine attaining a minimum alcohol level of at least 11%.
