Beer Science

The debate continues The leading brewer’s chemists in both England and Scotland may have been convinced that pure yeast was a dead letter in their countries, but the subject refused to lie down. In a paper given in Manchester in December 1900 to the North of England Institute of Brewing, entitled ‘The Development of Scientific Ideas, as Applied to Fermentation Industries’two academic scientists, Drs William A. Bore and H.C. Harold Carpenter, in applauding Hansen’s work and the transformation it...

Problems in Burton Murphy’s diversion was not followed up and instead Hansen himself returned to the fray in support of the views expressed by Jorgensen. In a letter to the Journal of the Federated Institutes of Brewing published in January 1900, characteristically peppered with references to ‘my pure cultivation system’- Hansen was very possessive of his achievements - he rehearsed the arguments and evidence in favor of pure yeast from both continental and British sources.

The instigator of this radical departure from custom and practice was Emil Christian Hansen, head of the Physiological Department at the Carlsberg Laboratory. Hansen’s original conception of the idea of pure yeast was that such cultures should be free from ‘disease yeast species’. It soon became...

While many women do drink beer, the association between men and beer is a strong one throughout the United States and Canada.

Some people become craft beer enthusiasts as soon as they reach the legal drinking age of their region and some craft beer people remain passionate about craft beer after retirement. Yet the stereotypical image of the middle-aged craft beer person might relate to yet another dimension of cultural identity. While it is undergoing important changes in this respect, craft beer is usually not seen as a typically “cool” drink by younger people in most parts of the United States and Canada...
