In this case study, a US-based bioethanol company engaged CPL Business Consultants to provide information on the market for Grain Distiller’s Dried Yeast (GDDY) and recommendations for its growth strategy. 


This market study assisted a client in understanding the market for brewer‘s dried yeast and also grain distillers’ dried yeast.

The client produced dried yeast as a by-product from its ethanol business and consequently required information about the market. This included the global market size (but with a focus on the US), value, prices, and how these yeasts are used.  Additionally, it required information on the products it competes against (can customers switch away from yeast if the price rises). Finally, it wanted information on value-adding IP  (e.g. as pre-mixes or similar to add flavour and allow salt reduction).

The project provided an overview of dried yeast market dynamics, in order to inform the client’s product growth strategy.


CPL identified 297 fuel ethanol plants either presently producing or about to come on-stream. Of these, 208 were in the United States and Canada, 84 were in Europe; 5 Chinese plants were also included

During the course of this study, CPL made ~70 direct contacts with individuals in companies participating in the yeast business, including producers, traders and users. In addition, through extensive use of professional networking groups, we made around 30 additional contacts with producers of products related or similar to Grain Distillers Dried Yeast (GDDY), end-users including animal nutrition specialists and North American traders.

We contacted yeast traders and producers of other by-product yeast from outside the US bioethanol co-products industry either directly or through networking groups. We prioritized the major bioethanol-producing countries, for example, Brazil, India, Germany and the UK.
