DOC area for white wine in the Italian region of Latium. The vineyards of the zone cover over 400 hectares of vineyards, which extend over the seven municipalities of Bolsena, Capodimonte, Gradoli, Grotte di Castro, Marta, Montefiascone and San Lorenzo Nuovo in the province of Viterbo. The historical Classico area includes parts of the municipalities of Montefiascone and Bolsena. If the grapes come from classified vineyards, Vigna followed by the name of the vineyard can be indicated on the label.
The unusual name is based on a legend. The Bishop of Augsburg, Johannes Fugger, or Joannes de Fuk in Italian (a reference to the famous merchant family is uncertain) was in 1111 in the retinue of Emperor Henry V (1086-1125). A servant of the clergyman tested the quarters and wines of the area for his high lord by moving from village to village and from inn to inn one day before the retinue. The wines of the localities were evaluated by him at the entrance door with chalk. With an "Est!" - meaning "It is (here)!" - the good ones were awarded with a double "Est! Est!!" the especially good ones. In an inn in Montefiascone he was so enthusiastic about the wine that he marked it with a triple "Est! Est!! Est!!!!". It is said that the bishop drank himself to death on the wine. On his tombstone it says: EST! EST !! EST !!! PPROPTER NIMIUM EST EST HIC JOANNES DE FUK DOMINUS MEUS MORTUS EST. He is buried in the church of San Flaviano in Montefiascone. In his honour, every year in August the wine festival "Fiera del Vino" is celebrated and a bottle of Est! Est!! Est!!! poured on his grave.
