Genetic engineering or recombinant DNA technology is now routinely applied to the construction and development of new strains of brewing yeast. This is a direct consequence of the power of the technology which facilitates the modification, introduction and stable maintenance of specific genes in brewing yeast, without compromising the intrinsic brewing properties of the yeast itself. The way in which gene technology has been applied to the development of new strains of Bass yeast is briefly illustrated by the provision of plasmid‐based systems for ensuring the stable maintenance of recombinant genes, the construction of amylolytic and β‐glucanolytic yeast and the design and development of genetic systems for enhancing the value of waste brewers yeast. Commercial and regulatory issues are discussed.
