PURE YEAST CULTURE. 239 



It may also be stated here that breweries which will have 

 nothing to do with my reform, do, nevertheless, in many cases 

 derive benefit from it in that they obtain at least a nearly 

 pure yeast from other breweries where pure cultivation has 

 been adopted. 



The position of my system in Bohemia is curious. As is 

 known, the brewing 'industry has attained to a prominent 

 position in that country ; yet it was late before pure yeast 

 culture was introduced, and long after it had gained recogni- 

 tion in several other countries. Professor Belohoubek was, 

 indeed, an early advocate of the reform, and at the same time 

 he proposed the founding of a brewing station in Prague ; but 

 it was only after this plan had been realised that the reform 

 made progress, especially owing to the efforts of Director 

 Kukla. In his report of 1891 (' Oesterreich. Brauer- und 

 Hopfenzeitung ') on the work of the station, he states that 

 of the breweries supplied with pure cultures of yeast, there 

 were twenty in which pure yeast exclusively was employed. 

 Some of these were foreign breweries, but I assume that the 

 majority were in Bohemia. It is a curious fact that all the 

 Bohemian breweries in which my system has been adopted 

 are small ones. The propagating apparatus has nowhere 

 been introduced, and, as far as I have been able to learn, 

 none of the large breweries have adopted pure yeast. The 

 position in Bohemia thus differs from that in other countries. 

 To attempt to trace the cause of this anomaly would lead us 

 too far from our subject. 



Before concluding this chapter, it will be of interest to 

 turn to North America. Here the pure yeast system has 

 made the greatest advance in recent years, and a glance at 

 the list will show that it has been adopted in the largest and 

 most famous breweries. Drs. Wahl and Henius state that 

 pure yeast has now been introduced with great success in 

 more than sixty North American breweries. In February 

 1894 they wrote as follows in the American 'Brewers'
