Bigi was founded by Luigi Bigi in 1880. Today it is the leading winery in Orvieto. Located just beneath the lofty walls of ancient Orvieto, Bigi is one of Italy's busiest cellars. The winery and cellars, redesigned and modernized by renowned oenologist Giacomo Tachis, draw thousands of visitors each year. Bigi is the leading brand of Orvieto with a thirty percent share of the total output of the zone. Equally important is the outstanding vineyard work done by Bigi. They own or manage almost 200 hectares (nearly 500 acres), notably Torricella, Orzalume, Viavalle and Il Poggio. Bigi thus controls the quality of its wines from vine to bottle under the direction of dynamic enologist Francesco Bardi, who is considered one of Umbria's most innovative winemakers.

Bigi Est Est Est Although best known for Orvieto, Bigi has always produced small quantities of “Est! Est!! Est!!!” from nearby Montefiascone. This historic wine has a remarkable story. Around 1100 A.D., Bishop Fugger was traveling from Germany to Rome for the coronation of Henry V. The Bishop sent his quartermaster ahead to scout out inns that had good food and wine. He would write “Est!” (Latin for "This is it!") on the walls of the best inns. He was so impressed with Montefiascone that he wrote Est!Est!!Est!!! on the wall of an inn there. Needless to say, the Bishop agreed and never made it to the coronation. He spent the rest of his life in Montefiascone. Local inhabitants, on the anniversary of the Bishop's death, pour a cask of Est! Est!! Est!!! on his grave in celebration of the notoriety he brought to their wine. Bigi produces a flinty, delicious white wine, which is as good as the story!!
