Images of giant colonies of different yeasts visualized by Paul Lindner. Lindner developed a method to distinguish strains and species of brewing and wild yeasts by cultivating giant colonies on thick wort-agar. The different morphology is evident. Colonies 1 (Saaz) and 2 (Frohberg) show the two modern S. pastorianus groups; colony 3 is an S. cerevisiae Berlin wheat-beer yeast; colony 4 is Saccharomyces farinosus from Danziger Jopenbier (current name Millerozyma farinosa); colonies 5 and 6 are wild yeasts (Lindner 1909, 1910, Hutzler 2021).
