Visit Erbslöh Geisenheim at the Unified Wine and Grape Symposium and learn more about how fantastic yeasts with exceptional characteristics. Dr. Jürgen Fröhlich, Head of the Yeast Development Department, Erbslöh Geisenheim AG, explains:
A wine yeast can reproduce in several natural ways. It is even possible that two related strains cross breed. The first generation of the breeding is called a hybrid. Generally it is tried to transfer the positive characteristics of the parents to the hybrid. In this process a huge number of different offspring are produced. Those hybrids, which have beneficial characteristics for winemaking, are selected. In addition to this cross breeding procedure, a hybrid can be obtained by merging the parental cells together.
This technique is called protoplast fusion. It is a way to create a new microorganism GMO-free and to combine the beneficial characteristics, as for example extreme fermenting power and aromatic versatility, of two different yeasts. In opposite to classic cross breeding, two cells are merged to a so called “cybrid” after their cell walls have been enzymatically hydrolysed. Then the two nuclei fuse together and a new hybrid is created (figure 1). The advantages of this technique make it possible to use even cells which lack the ability for sporulation and to combine strains just remotely related to each other (e.g. Saccharomyces and Torulaspora).
To produce ErboFerm X-Series this method was used. The technique allows to create “fantastic” yeasts with exceptional characteristics.

Erbslöh Geisenheim AG has been in existence for more than 100 years. Today our company specialises in processing and refining of fruit-based drinks and is a leader in research and development and the manufacture of treatment agents. Even Erbslöh’s move into beverage technology more than 50 years ago was the result of an exceptionally innovative idea. This pioneering spirit is still what drives our family business. The challenge we face is to consistently think of the “future”, both nationally and internationally. From when we were founded until today, we have been governed by the progressive opportunities which innovative products and processes open up for our customers.
