Physical-chemical parameters of the three craft durum wheat beers at t0, one brewed with commercial yeast (S33) and two with autochthonous yeasts isolated from sourdough (S42, S38), used here for the first time, were reported in Table 2. As can be seen the fermentation occurred to a greater extent in the beer fermented with the autochthonous yeast S38 that showed the lowest value for apparent extract.
