Hefe is obviously yeast, and Trum is a scholar of brewing history, so I assume when he cites Hef(e)ner, he's referring to actual brewing jobs in medieval Germany.

"bottom fermenting" is just one of many characteristics a yeast can have, like attenuation or flocculation. All lager yeasts (to my knowledge) are bottom fermenters. Older ale yeasts were absolutely top fermenters, and you still see it in a few heirloom strains (the fullers strain, hefeweizen strains, and so on are pretty notorious topDaniel Warnernoreply@blogger.comtag:blogger.com,1999:blog-21271644.post-13971185397097113182013-01-17T07:19:18.626-08:002013-01-17T07:19:18.626-08:00In White and Zainasheff's "Yeast," t...In White and Zainasheff's "Yeast," they make a more qualified claim about Pasteur's role as "discoverer." Their assertion is that he proved that the obvious byproducts of alcohol and carbon dioxide were definitely biologically derived, and that yeast was definitely a a living organism which metabolized sugars and primarily produced these byproducts.

It was because of Pasteur's work to fight spoilage that gave him a bit more noteriety.
