A large, thin-skinned grape similar to Poulsard or Schiava, Trepat produces light-bodied, aromatic wines reminiscent of Jura reds. Albert and Mariona write: "When we started as a company, our calendar was strict, so adapting to these timetables was an obligation for us. One night, we went to pick up samples of grapes from one of the properties which provide us with the grapes for this wine, and we saw a firefly, which inspired the name of the wine."
