3822-PC Belgian Dark Ale

Species: Saccharomyces cerevisiae var. diastaticus

This unique Belgian ale yeast is a high acid producer with balanced ester and phenol production allowing a good expression of malt profile, especially the strong flavors of darker malts and sugars. High alcohol tolerance. Spicy, tart, and dry on the palate with a very complex finish.

 

This Wyeast yeast strain has been classified as Saccharomyces cerevisiae var. diastaticus using rapid PCR analysis. This strain carries the STA1 gene, which is the “signature” gene of Saccharomyces cerevisiae var. diastaticus and will be found in all diastaticus strains.

3538-PC Leuven Pale Ale

Species: Saccharomyces cerevisiae

A complex alternative to the standard German wheat strain profile of 3068 Weihenstephan Weizen. This strain produces apple, pear, and plum esters in addition to the dominant banana character. The esters are complemented nicely by clove and subtle vanilla phenolics. The balance can be manipulated towards ester production through increasing fermentation temperature, increasing the wort density, and decreasing the pitch rate. Over pitching can result in a near complete loss of banana character. Decreasing the ester level will allow a higher clove character to be perceived. Sulfur is commonly produced, but will dissipate with conditioning. This strain is very powdery and will remain in suspension for an extended amount of time following attenuation. This is true top-cropping yeast and requires fermenter headspace of 33%.

3463-PC Forbidden Fruit

Species: Saccharomyces cerevisiae 

A widely-used strain in the production of Witbier and Grand Cru. This yeast will produce spicy phenolics which are balanced nicely by a complex ester profile. The subtle fruit character and dry tart finish will complement wheat malt, orange peel and spice additions typical of Wits.
