he sensory profile between storage temperatures. Only a significant
difference for foam persistence was perceived with higher
values at higher temperature. Differences between yeasts at t0
were found only for fullness, being more intense in the autochthonous
yeasts S38 compared with the commercial one.
In conclusion, the three beers, two of which brewed with
sourdough yeasts, showed similar physical-chemical, volatile and
sensory characteristics during aging. This suggests the possible use
of autochthonous sourdough yeasts in brewing, providing an
additional element of authenticity to existing production in order
to create a stronger regional link, with positive economic returns.
As far as we know, here it is presented for the first time, the
aging behavior of craft durum wheat beers. Further studies could
focus on shelf life of beers over a longer period in order to improve
product stability and thus enhance the potential for expanding the
craft beer market outside of the local region. Finally more research
is necessary to enhance the knowledge about the sourdough yeasts
behavior in brewing technology to confer originality to the product
beer.
