Beyond for modern lager brews: Exploring non- hybrids with heterotic maltotriose consumption and novel aroma profile.

Non-domesticated, wild yeasts have promising characteristics for beer diversification, particularly when used in the generation of interspecific hybrids. A major motivation for the current work was the question whether attractive novel interspecific hybrids can be created for the production of exotic lager beers without using the genomic resources of the ale yeast . Importantly, maltotriose utilization is an essential characteristic typically associated with domesticated ale/lager brewing strains.
