''Toluraspora Delbrueckii'' is species of yeast, that is round to ovoid in shape and has been traditionally used in some wine fermentations to increase the complexity. Most of the commercial Torulaspora species and strains were isolated from soil, fermenting grapes (wine), berries, agave juice, tea-beer, apple juice, leaf of mangrove a tree, moss, lemonade and tree barks. Although it was said that most ''T Delbrueckii'' strains would not fully attenuate or tolerate higher alcohol contents it has been shown that is strain dependent.  ====General Information==== Analysis was done on 10 different ''T Delbruckii'' strains on various types of resistances as well as the ability to metabolize different carbon sources.  =====Hop Resistance===== The resistance to alpha acids were also measured among these 10 strains using 0 PPM, 50 PPM, and 90 PPM. All strains were found to be resistant to these levels of alpha acids not affecting their growth.
