06 Mar 2015 --- VTT Technical Research Centre of Finland Ltd has been the first to publish a scientific study on the successful generation of hybrid lager yeasts. For centuries the same few yeast strains have been used in the production of lager beer, in contrast to ale, whisky, wine and cider, for which there is a wide range of yeast strains available to produce different nuances of flavour. VTT has been developing hybrid lager yeasts so as to impart new flavour to the beer and accelerate the production process.
