Have a look at our PowerPoint Introduction and Brochure describing deliverables, differentiators and case studies. Eight case studies can also be reviewed.


The purpose of this market study was to assist our client to better understand the market for brewer‘s dried yeast and grain distillers dried yeast.

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

The objective was to understand the market dynamics of the dried yeast business, so that our client could better plan the development and further exploitation of its in-house dried yeast product.


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 and 5 were in China.

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