The loot would have netted them about €1,000 had they not been caught by vigilant vineyard guards, Bari Today reported.
The three – reportedly known to police – are 59-year old Gaetano Tatulle, 49-year-old Francesco Mongielli and another 61-year-old.
They are now under house arrest, while the grapes have been returned to their rightful owner.
