added yeast bay METSCHNIKOWIA REUKAUFII
| [[Mainiacal Yeast]] || Hardened Spaniard || Zygosaccharomyces parabailii || 76-100%
|| || || This species is generally found in Sherry wines. It's most commonly referred to as a "Flor" yeast. Is is a oxidative yeast that also forms a heavy pellicle with access to O2. It's best used in secondary environments but can be used in primary. It lends notes of fresh cut apples and earthy/hazelnut like flavors.

| [[The Yeast Bay]] || Metschnikowia reukaufii || ''Metschnikowia reukaufii'' || 20-25% (cannot utilize maltose) || Med-High || || ''M. reukaufii'' is a nectar specialist that was isolated from flowers in the Berkeley Hills of California. Evolutionarily, these yeast likely evolved to produce a more odorous and attractive nectar for pollinators by enzymatically altering otherwise inodorous nectar compounds like glycosides.
While only attenuating to 20-25% in brewer’s wort and not utilizing maltose or maltose polymers, in co-fermentations it has been shown to drop gravity and pH of the fermentation faster, accentuate and modulate the flavor and aroma profile and soften the perceived bitterness of the finished product. This accentuation of the aroma profile is likely due to not only the complex though rather subdued fruit cocktail ester profile of M. reukaufii, but also to the production of glucosidases (exhibited by others in the genus) that utilize hop glycosides as substrate to free flavor active molecules from the sugars to which they are bound. This strain MUST be used in conjunction with other yeast that can ferment brewer’s wort (capable of fermenting maltose).
